You’re now approved to DJ with your iPhone. Or at least the app is. I’m not sure if I can take credit for getting Apple’s attention, but Apple has approved the TouchDJ application from Amidio. That’s big news, partly because developer Amidio has consistently been at the forefront of musical development on the platform, including their Noise.io synth and wild hexagonal JR Hexatone Pro.

This also is a big blog to the theory that Apple is intentionally blocking DJ apps — and a big boon to the theory that the App Store is just plain clogged, even if it may be disproportionately affecting more sophisticated applications.

Features in the release:

• “Visual mixing,” with a clever interface that uses overlays atop side-by-side waveform views
• Pre-listening using a special left/right adapter
• Faux vinyl and spin effects
• Real-time scratching, looping, positioning, EQ, effects, re-pitching
• Onboard sampler with 3 WAV sample slots, recording from the mic
• Uses a separate MP3 library with companion apps, since it isn’t possible to DJ from the library you sync from iTunes

Now, to me, that last point is a fairly significant one. You have to load tracks you wish to DJ separately, in MP3/M4A format. And I’m sure that this will start various debates about whether you’d want to DJ on your iPhone in the first place. But don’t look at me — I just work here. I’d be remiss if I started out the week talking about apps stuck in iPhone limbo, only to ignore them immediately becoming available. And I will say, Amidio is one of the smartest mobile music developers out there, so it’s worth checking out the range of what they’re doing.

Whether petitions and news stories did help this app to get to the top of the queue or not, I have no idea. I think maybe I’ll start running screaming headlines with things I want in them, if only for good luck.

Tomorrow on CDM: “You Know What Annoys Me? The Fact That We Don’t Have Unicorns. Magic Unicorns. Who Speak OSC.”

A powerful DJ application for your iPhone or iPod touch may be a tantalizing prospect. But several would-be candidates aren’t available to you yet. Why? They’re languishing in Apple’s approval process, with no sign of whether they’ll be released or not.

For all the success of Apple’s App Store, some developers and users continue to express frustration at what they believe is a sluggish, unpredictable approval process, restrictive Apple policies, and Apple’s complete control over distribution and categorization. That now leads to two complaints from music developers. A number of music developers want more delineation from Apple’s categories, so that the flood of general music apps don’t drown out powerful, creative tools. Meanwhile, developers of DJ applications claim that Apple is discriminating against DJ apps, which they say has led to delays without explanation.

“Open” development is relative, without question. Game system makers require developers to prove to them why they should be “allowed” to create titles, leading to a tightly-controlled stream of approved titles. But the success of Apple’s relatively open development model has prompted many software creators to hunger for greater freedom. I’ve increasingly heard people enthusiastic about the more flexible distribution model on Google’s Android (and other Linux) platforms, which allow users to install apps they want. I even moderated a mobile music platform panel at the CMJ music conference at which a Verizon representative, no less, talked about wanting to be more open to applications. The benchmark was Apple, for being perceived as overly restrictive.

iPhone/iPod touch developers, however, aren’t simply ranting against Apple. They’re complaining because they’re enthusiastic about the App Store. They want changes from Apple and believe there’s potential to get what they want. That said, I think they also illustrate potential for rivals like Google to outdo Apple – assuming those rivals invest more time and effort into courting these kind of applications.

Is Apple Blocking DJ Apps?

First, some developers believe that Apple is intentionally blocking DJ applications from being approved. Whether intentional or not, a number of potentially ground-breaking applications are unavailable after a significant delay. Kasabian Kasabianmeister writes:

Apple is deliberately not allowing DJ apps to the App Store

Something really strange is going on with the Apple review team. They now seem to approve all kinds of applications, even the ones that have been previously considered "unacceptable", but there is one kind of applications that are simply kept "in review" stage for months without any explanation.
http://www.youtube.com/watch?v=tVv4PY6st6Y

These are the DJ applications that have been developed with the idea to give the user the ability to mix his own MP3 tracks on the iPhone. Currently, there is no application in the AppStore that has such functionality. Of course, this wasn’t left unnoticed by the developers, but…

At least 3 applications: Touch DJ (www.amidio.com), Sonorasaurus (www.sonorasaurus.com), DJ Player (www.djplayer.fm) are not being approved since the beginning of September, hitting the 2-month "in review" mark. One of the developers even made a video voicing the frustration over the absolutely unacceptable behaviour of Apple:
http://www.youtube.com/watch?v=jDUS_2rcAjw

What is really weird and unprofessional, Apple doesn’t give any reasons whatsoever what is the reason of such delays. The developers are just told to "wait" without any explanations.
Meanwhile, the demand for the DJ apps is so high that people even started an online petition entitled "Apple, Allow DJ apps on the iPhone!":
http://www.petitionspot.com/petitions/iphonedj

One of the reasons for such attitude could be that Apple is working on its own DJ app, or is waiting for a DJ app from a "senior" player and keeping the possible "competitors" aside. In any case, it is quite possible that we will know the real reason soon.

It’s worth noting that, in the past, Apple’s application process has simply proved to be inconsistent and slow, which can cause people to see intention where there is none. But that doesn’t necessarily excuse Apple’s App Store approval process. The iPhone and iPod touch are popular largely because of Apple’s success at making media playback devices. Apple needs to document what it views as acceptable use of these devices. In the absence of information, developers are jumping to their own conclusions, possibly accurately, possibly not.

Obviously, aside from interest in Apple’s policies, I’m sure many iPhone and iPod touch owners are eager to see these applications, so we’ll certainly be following them to see if any are released.

In other rejection news… The App Store is currently just letting these DJ apps languish in limbo rather than providing a rejection. But another significant set of rejections is game titles built with the Unity game engine. There, the issue appears to be the presence of support in the engine for a private API call from Apple, whether or not the title itself uses the API, and …uh, yeah, that one’s complicated. Updated TUAW tells us via Twitter that Unity developers say they’ve fixed that issue, so… move along, nothing to see here.

Do Music Apps Need Better Categorization?

One potential danger of having a centralized store like iTunes and the App Store is giving control of approval to a single company (Apple), as seen in the DJ apps. The other is that such a storefront will simply not be categorized in a way that allows people to discover apps successfully.

Apple has been roundly praised for creating a store that encourages people to consume apps. Now, some developers want Apple to tweak their categorization to allow some of the most creative applications to stay in the forefront. Over the summer, Jokton Strealy, maker of the excellent songvoo music collection management tool, issued a call to fellow developers to try to get better categorization from Cupertino.

Side note: songvoo is just the sort of app that critics of the App Store might assume would be impossible. It replaces the existing playback functionality of the iPod and iPhone, the sort of replacement app that has sometimes earned rejection from Apple. Evidently, if an application is differentiated enough, it can clear Apple’s approval hurdles. (On the other hand, inconsistent policy and overzealous restrictions are at the center of some of those criticisms.)

But Strealy has no complaints about the App Store itself or the approval process. He just wants a more intelligently-organized store. Here’s his open letter from the summer, which has since earned a lot of support from fellow developers:

Recently, the Music section of the App store has gotten very busy with a new type of app — let’s call them Artist Apps or Fan Apps. Some of these Apps are great resources for fans and artists reaching out to their fans and potential fans, and some don’t live up to their potential.

However, they are joining a category that previously moved a lot slower, as the apps that had been populating this category were apps with a lot of development put into them and therefore sold at a higher tier usually- but were released at a slower pace. A look at the top 100 paid music apps illustrates this nicely.

Customers perusing the music section to catch that next great sound generating tool (for example), could check in on the new releases section perhaps once a week or even once a month and have the opportunity to check out all the great new apps that had been released, without worrying that one was missed.

Now however, these newer Artist apps have flooded this category, and great apps are getting lost in the shuffle. On one day last week, there were 21 pages of Artist or Fan apps, with a few "other" apps strewn in the mix here and there, very hard to pick out of the jumble.

I understand that this may be happening in other categories for other reasons, but I only concentrate on the Music section since I am a music producer and music App writer.

I propose that we all get together to come up with some suggested sub-category names for the music category. I will start the list off and hopefully some of you will chime in and give suggestions for other categories or add more definition to a sub-category that is already here.

Once enough input is received, I will compile it into one bug report for Apple. i will then post the bug# for everyone to include with any correspondence with Apple on this issue.

New sub-categories for the Music section of the App store.

Music Creation:
Synthesizers, drum machines, sound generators, scoring and notation, sequencers, DJ apps, recorders (multi track)

Music Utilities:
Lyrics apps, iPod interfaces, visualizers, iPod controllers, song recognizers, concert finders

Learning:
Metronomes, guitar and voice tuners, music slow downers, guitar tutors, chord apps,

Artist Apps/Fan Apps:
iLike apps, Deadmau5 app, PVD App, Underworld App, NIN, etc.

Radio Tuners:
AOL Radio, Pandora, Last.fm, individual radio stations

If nothing else, the explosion of development for iPhone and iPod touch is prompting some lively discussions about just what development should look like. A lot of what you hear is praise for the Apple model, but I expect some of the criticism of it – even down to minor details – could be productive, as well. I’ll certainly be watching the development of both of these issues, and we’ll see if Apple responds or not.

Updated: Jokton notes an additional change to the way apps are listed.

As for my original issue with categories and release dates, there has been a new development. Apple recently stopped listing “updates” in the “release date” listing of each category. Now the only way to get a listing there (which generates sales) is release a new app (1.0). Before that, devs were releasing constant updates to an app to keep it “on the radar” on the app store, even if the update were a simple as correcting a spelling error or perhaps even faking issues to correct. That in itself created a lot of “update spam”. Many developers are up in arms about these new changes because previously this was the only way to get your app seen by the masses. There has been no official word from Apple on the issue, so it is still unclear if this is a permanent change or some kind of error in the system. If this change is indeed permanent, then the argument for more subcategories is even more important now.

As computer music practice – part composition, part instrumental play – spreads, the idea of software interface as performance tool is becoming second nature. Putting those opposable thumbs and sensitive fingertips to work, multitouch controllers are growing in number, variety, and sophistication. Berlin-based artist Marco Kuhn shows off his beautiful creation, the PlayBox multitouch hardware, and its first app, PlayLive. That first software focuses on Ableton Live performance, but Live could be just the beginning – Marco has worked with Pd in the past and promises other apps to come. He’s interested in selling this device in the future, and he shares with us the tools he used to create this work for those of you doing development along similar lines.

The Project:

“Play Box” is is a User Interface for Natural User Interaction.
? allows multi-touch and object recognition (TUIO marker)
? hovering is also possible
? 22 ” TFT display , 1680 x 1050 pixel
? robust
? plug`n play

“Play Live” is a dedicated multitouch controller surface for Ableton Live.

- GUI Elements support multi-touch interaction
- easy to setup , just load the “Play” Control Surface
- you need no controller assignment
- you can control 32 tracks and 127 scenes, that are 4064 clips
- track controls are mute, solo, record, send1, send2, pan, level
- scene feedback name and state
- clip feedback color, name and state
- Transport control
- 2 Returns
- Master
- support bidirectional communication
- display track level meter, name

The whole app is coded in python.
- use Python Ableton Live API
- and libavg www.libavg.de for the GUI and Trackingengine
- PyPortMidi receive/send Midi Messages

“Play Live” Future plans:
- FX View per Track
- subpage for abstract clip controlling

I tested it with my mac book pro, “Play Live” and “Ableton Live” is running at the same machine. It should work on all platforms (Windows, Linux, Mac OS X). That Project started with my Diploma Thesis in Applied Computer Science 1 year ago.

Everything is coded and built by myself. The GUI – elements has been designed by Gösta Wellmer.

In this work, I created a GUI-Controller Library which allow me to Develop very rapidly Multitouch Interfaces for other Audio Environments.
More Apps coming soon ;-)

I [plan] to sell the” Play Box” and Apps like “Play Live” if anyone is interested.
The price is yet not specified.

That`s not my first multitouch Interface. 2 Years ago I created forfour – http://forfour.hi-pi.de/
- used PD, Processing, Reactivision and OGRE.
But the “Play Box” is another level;-)

I hope to have video to share soon – and yeah, it’s time to plan another visit to Berlin.

Imagine drawing an interface on paper, then being able to use it as a musical interface. Or, heck, don’t imagine it – do it. Unfortunately, the kinds of intelligence necessary to make the music video in yesterday’s post just aren’t practical yet. (That is, you could draw a picture of a keyboard, and even use the picture as a music controller, but while you or I could recognize a keyboard from a drum pad and know that line is a fader, a computer would need some sort of advance structure for any recognition to work.) But you can do some really clever things, as folks have shared in comments.

And using some basic paper interfaces, you can make entire instruments for just a few dollars.

Of course, the awesomest way to do anything is with LAZORS. Greg Kellum and Alain Crevoisier presented a paper at last year’s NIME (a conference for new interface designs for music) proposing a system for making any surface a control surface. Like the music video yesterday, you can configure your surface to function however you like – even dividing it up into pads and faders.

By now, you’e likely seen plenty of multi-touch interfaces or means of tracking hands. But, to paraphrase the NIME paper, these either require a special surface (or transparent surface), or they can’t actually detect when you’re touching. You can even use multiple cameras or an IR beam, but there are limitations to accuracy and the size of the usable surface that would result. Kellum and Crevoisier use an infrared camera and two illuminators, each built by pointing a laser at a mirrors.

Yawn, you say, been there, done that, seen Jeff Han’s video… The advantage of this system is that you can use any surface, like your dining room table. And you can configure that surface however you like. There’s even a freely-downloadable Surface Editor you can extend in Java and Processing. The creators claim they can even get input latency down to a reasonable 10 ms using high-speed cameras.

Thanks, Randy Jones!

db3ll has created a keyboard out of paper, and of course it works better than those flimsy rubber “roll-up” pianos you see for sale. “Conductive ink is what I used,” he says, “painted on as traces on the non-printed side of the paper.” That’s the twist – I had assumed you’d use the top of the paper, but the trick is to use the reverse side to provide the “wiring.” He also offers advice for making a fader:

You can make a paper thin fader in much the same way, but it requires a magnet. Cut a slot in a piece of paper, color around the slot with conductive ink (I use the “trace repair” pens sold at electronics supply places… it has a very fine tip), and glue some SVHS tape (resistive side up) under it. Put a thin piece of metal beneath the SHVS tape & use a magnet to conduct between the SVHS tape & the conductive ink. The magnet will stay in position due to the metal (I use package banding) under it, and aside from the magnet, it is roughly the thickness of a couple sheets of paper.

Simon Lacelle is also working on a project I’m eager to see:

In a pad controller I’m making using a HUGE Staples calculator, I’m using strips of aluminium foil separated by a sheet of paper with holes at each button as switches merely a milimeter thick, and these are quite responsive.

A YouTube uploader by the name of DJ Mocap appeared briefly online with a project that seems to show him controlling Traktor with a drawing. There’s a camera and some sort of analog input being fed into a circuit board, but I’m not entirely sure what’s going on – though I can think of a couple of ways to make this work. It stumped DJ Tech Tools’ readers, but I have a feeling it can’t stump CDM readers, so have at it.

UPDATED – FAKE (but possible) Okay, so this turns out to be a Stanton touch controller hiding underneath a piece of paper. Of course, that’s itself not such a terrible idea – by having a drawn overlay, you have visual feedback for specific positions on the controller. But furthermore, while this is fake, the idea remains possible – and more cheaply than buying a piece of Stanton gear to toss under your piece of paper. So I call this “fake but potentially inspiring.”

Thanks to Gizmo from Scratchworx. Now, show Gizmo and Mocap by making a real version of this!

Just to consider moving in the opposite direction, I have to point to Amit Pitaru’s Sonic Wire Sculptor, an interface for drawing virtually and digitally. Because it’s digital, you can draw in 3D, do something you can’t with real-world markers. Here it is in a Tokyo gallery installation version; see more information (or try it yourself online) at Amit’s site.

And back to the realm of the imaginary – could MPCs of the future be made out of cardboard? (Oh, how I love reading YouTube comments. “Doesn’t look too sturdy.” “Why do you have your MPC in a box?” Apparently some people thought this was somehow insulting hip-hop. YouTube comments – pushing the very frontier of stupidity.)

Thanks to dyscode on comments — brilliant.

The cardboard MPC comes from theycontrol.us and our friend Elijah Torn, as seen previously on CDM.

Doing it Yourself

If you’re interested in entering the world of paper, drawing, and controllers, there are two directions I’d suggest.

One way to go is to simply start thinking about drawing as an interface. The creator of Tablet 2 MIDI, a MIDI-graphics tablet interface, suggests that using the pen you can draw any interface you like, then map it to tablet input. That concept could certainly be applied more broadly.

As far as using paper and a conductive pen to doodle your own musical creations, it turns out this is one of the easiest ways to learn about resistance in electronics.

Learn Musical Electronics, No Soldering: Free PAiA Ribbon Controller Kit for CDM Readers

This project, which we covered at the end of 2007 and featured at our Handmade Music event, is ideal for giving young people (or the solder-phobic) their first step into electronics. The whole kit fits on a business card; you just need speakers to which you can connect.

The Drawdio project uses the same basic circuit and principle, but attaches it to a pen, making the rig a little more portable and allowing other fascinating experiments. It’s also available for purchase.

http://web.media.mit.edu/~silver/drawdio/

You’ll find countless variations of the basic circuit, because it’s so simple, and it’d be a great way to get into the more sophisticated (or at least more complex) ideas here.

Other ideas? Questions? Stuff I’ve left out? Let me know, and I’ll update the story.

It’s still anyone’s guess exactly what fruit parent technology maker Stantum may soon ship, but the JazzMutant Lemur touchscreen is getting a component update soon. Nat Lecaude points to a quiet MySpace post from JazzMutant with the details of a coming manufacturing change.

“…the next batch of Lemur will feature the latest generation of our multi-touch technology: better optical performances, higher precision, greater accuracy and responsiveness. It will be clearer and have brighter colors. We plan on launching the new Lemur in early October, and of course we will keep you updated as we get closer to launch date. We once again thank you for your patience, and look forward to sharing the excitement early October!”

It’s actually quite remarkable to me that JazzMutant remains alone in this market – and with Stantum focused on the mass market, that could be the case in the future, too. The issue is that doing multi-touch well still costs some money. There are basic implementations on computers that are cheaper, but that restricts you to a few computer models, because slapping multitouch overlays on displays remains pricey. So HP can get a few computers to the mass market, but not without cutting some corners and not even on that company’s full range. The iPhone has brilliant multi-touch control, but a mobile form factor makes this much easier.

I’ve got some videos demonstrating what’s possible with the Lemur coming soon, as well as some notes on how the software has evolved since I first saw it in its initial release. Even if you don’t want or can’t afford a Lemur, it’s a fascinating demonstration of interaction design and OSC, with lessons (inspiring and tough alike) for other interfaces.

There’s plenty of rightful skepticism about the use of mainstream displays for multitouch in general purpose computing. And why not? As a full-time replacement for other input, multitouch probably doesn’t make sense. But for music, the equation is changing. Multitouch capabilities are showing up on commodity-priced PC computers like the multi-touch enabled HP laptop models – the tx2z seen here starts, incredibly, at US$850. And because computer musicians are looking for more control, having a touch-enabled display (even single-touch) just makes sense.

The screen for a laptop musician is a huge piece of real estate. Finally, instead of sitting dumbly in front of you glowing, it can become an X/Y controller or give you shortcuts for controls or provide additional parameters. Yes, using a touchscreen exclusively can result in the dreaded “gorilla arm.” The ergonomics of using a vertically-oriented screen are extremely poor – if you use it exclusively for an extended period of time. But if you look at the way people are using these touchscreens, for incidental control in combination with other things – and the ability of convertible laptops to transform into a horizontal orientation – I think this is no longer the deal killer it once was.

At top, an HP laptop ($850) plus the free version of Sensomusic’s Usine is all you need to create a multitouch interface for Ableton Live. Correction: right now this is limited to single touch only, but multitouch is supported in the hardware, in drivers, soon in Windows 7, and support is promised for a future version of Usine. The point still stands — as does the ability to optimize controls for your fingers. Being able to use more than one at once will, of course, be that much better.

Fractal (see Myspace) uses the combination to play Ableton Live with some simple controls. If you get hooked on Usine, you can get the full “Pro” version for EUR70 with additional patches and objects.

The one major remaining obstacle to multitouch, at least, is cost. If you don’t especially fancy buying a new HP laptop, add-on kits still run in the range of US$800-900 (meaning, ironically, you might as well just buy the HP instead). Laptop vendors are still slow to adopt the technology, though that could change when Windows 7 ships later this year. (On the other hand, tablet PCs, even when they were shipping in relative quantity, often were constrained in available configurations and either skimped on specs or demanded a significant premium.)

But let’s not complain too much. The simple reality is you can add an HP laptop now to a live rig as a performance instrument for under a grand.

To see something else with Ableton Live, here’s a video by Andrew Coenen from earlier this year of Pance Party’s Bartelby playing Live with the open source Max Multitouch Framework. This is a more sophisticated setup – it requires a table-style setup using the Frustrated Total Internal Reflection tracking method. But the idea is basically the same. (By the way, Max 5 is an optimal choice because of its excellent widgets, and it’s great having this choice, but it’s a little odd having an “open source” framework in proprietary software. If you want a fully open source solution, there are options like PyMT, which we recently saw on Create Digital Motion. And that said, there’s no reason you can’t try out both.)

And yes, someone has done Reason, too (poor-quality video, but gives you an idea).

Updated: As I’m posting this, I see that Oliver Chesler is writing about how effective touch interfaces can be for synthesizers – just using iPhone as the example (but the idea still holds). And, in fact, you don’t necessarily even need multitouch to make this work; single touch would be effective.

The example: an upcoming iPhone/iPod touch synth from the folks who gave us the Curtis granular synth, The Strange Agency.

Sound Scope Space for the iPhone [Wire to the Ear]

Sound Scope Space demo from strange agency on Vimeo.

Of course, I have to point out at this point, this is another reason that OSC (OpenSoundControl) support becomes essential. Whether or not conventional gear vendors adopt OSC, it’s a logical way to deal with the growing number of touch-enabled devices, from your own display to your iPhone.

I expect this could all accelerate as we near Windows 7’s release. (You don’t need Windows 7 – HP is doing just fine without it – but the presence of in-box APIs for paging through photo galleries and the like is almost certain to encourage Microsoft’s hardware partners.) Stay tuned.

Sensomusic Usine + Ableton Live = Modular Touchscreen Interface

First up, here’s a demo of the new app FingerPlay MIDI, which turns Android into a simple touch controller. True, we’ve seen similar things on iPhone, and Apple’s platform has precise multitouch which Android lacks, but it’s nice to see the concept extended across platforms. Big thanks to postromantic on Twitter for the tip! (Follow cdmblogs for more.)

FingerPlay MIDI

I can’t tell yet if this will be open source – that would actually be nice, I think, as it’d allow the community of developers to have a shared set of tools. (In fact, it seems a logical model would be to cash in on general-market apps and open source the more music-specific, niche stuff.)

In other Android mobile news, Christopher Souvey continues to work on his Musical application and the Musical Pro desktop app. The desktop client works with MIDI over Wifi, and thanks to the Cupcake OS update, latency is greatly reduced after a complete rewrite and the creation of custom drawing and event handling and controls. Check out the slick new tuner and UI Christopher has been developing, too.

This play-along piano is probably not something any of you folks desperately need, but it is a good demonstration of what’s possible.

Another interesting thread to follow will be the growing power of Web apps. On Android, you’re already able to combine a Web app with the Java APIs, and going another level, mobile apps with native ARM code for the processor. Translation: while phones still have a fraction of the power of your computer, it’s getting easier for developers to work across platforms and to take advantage of what power is there. That’s leading to trends that could be of use not only to a single platform (Android, iPhone), but to mobile devices in general.

The beauty of using touch for controllers is flexibility. Sure, you give up tactile feedback – but you can also quickly make your own layouts, make touch controllers an ideal complement to your existing hardware gear (the stuff with physical knobs and faders and pads).

For that reason, we’re all eagerly anticipating an upcoming version of the awesome OSC-based iPhone/iPod touch controller, TouchOSC.

http://hexler.net/software/touchosc

The included layouts are already fantastic, with rotaries and virtual buttons and multi-faders and toggles and X/Y pads. But custom control would be even better. Creator hexler writes CDM with the latest:

The long-awaited update to TouchOSC that will allow for custom layouts has just been submitted for review to Apple,
so I hope that as soon as next week it will be available as a free update to all users on the App Store.

Together with this release (1.3) there will be a free editor application to visually design and upload layouts to the device. You can take a look at the last beta version I published if you want, there’s both Windows and OS X versions available, but I will also prepare a Linux version as soon as possible, of course without the new version of TouchOSC this is but a preview of things to come:

http://dev.hexler.net/touchosc/touchosc-editor-0.7-osx.zip
http://dev.hexler.net/touchosc/touchosc-editor-0.7-win32.zip
http://dev.hexler.net/touchosc/touchosc-default-layouts.zip

And nicely enough, the editor is built in cross-platform Java, which I think makes a whole lot of sense. (Go Java, Python, etc., rather than getting stuck in hard-to-port platform-specific stuff like Cocoa.)

Thanks, hexler! I don’t have a video of the new features yet, so instead here’s a nice novelty – the beginnings of a creation using the free SuperCollider (which runs OSC natively) in combination with TouchOSC to make a custom step sequencer. Should fuel other ideas, too:

No doubt about it: touch is coming to more screens near you. But there’s no need to disappoint your current beloved laptop. $200 kits can turn your laptop into a functioning touchscreen.

Now, as I’m working with JazzMutant’s Lemur this week, before you get excited, this is no Lemur – or even anything like your iPhone or iPod touch. Sensitivity and accuracy are workable, but not exceptional, the overlay is pretty simple (as you can see in the video) rather than integrated with the display, and this is single-touch only — not multi-touch. Lastly, on a conventional laptop that isn’t convertible, you may miss the ability to fully extend your laptop perpindicular to your body. (Having the screen be parallel can put your arms in a fatiguing position.)

But that said, there’s a lot of potential once you have the ability to reach over and make quick gestures on a laptop screen that control a set. You might make your own instruments and effects or controller dashboards in a tool like Processing or Reaktor. And at $200, this could be a brilliant way to retrofit a machine and breathe new life into it. There’s support for Mac, Windows, and Linux; you just plug in via USB.

In this case, Sensomusic Usine is perfectly suited to the job, with an interface built just for this purpose. Their Touch Screen Edition earns major kudos for being a full desktop computer music environment built around touch, as covered here previously.

Of course, all of this potential is likely to make you want more sophisticated, multi-touch solutions even more. The outlook is improving. Windows 7 will bring native support for multi-touch gestures – not so much important news in itself so much as a sign that more hardware vendors could add support, ramp up volume and lower prices. HP is already shipping computers (including laptops) with multi-touch.

Also interestingly, the creators of the JazzMutant Lemur multi-touch hardware – specifically designed for music and visuals – have now expanded their mission to targeting general-purpose devices. The new company, Stantum, is showing off fantastic, unique technologies for multi-touch, as seen recently in an Engadget preview. Beautifully designed as the iPhone is, these offer some unique features like intensive accuracy and support for input from objects (like styluses) and not just fingertips. That could mean the Lemur is just the tip of a much bigger iceberg.

Here’s a tantalizing look at the Santum SMK screen working with Max/MSP. Unlike the Lemur, that means direct controlling Max’s widgets, rather than treating the screen like an independent controller.

Of course, that doesn’t mean the simpler, single-touch, cheap solution couldn’t be a great project right now, and a chance to get a leg up on The Future. If anyone tries one, let us know what it’s like.

For that reason, you may be intrigued to see this video of Zen Piano, a demo app for the iPhone and iPod touch. The idea: respond not only to the position of your finger taps, but also to how hard you’re tapping the phone That promises “velocity-sensitive” tapping, which would make touchscreen interfaces more powerful.

Here’s the somewhat overheated description by GreatApps, who say their “patent-pending,” “cutting-edge” technology is the result of “having gone through the research and development phases.”

TapForce^TM has been developed from the ground up to provide a completely intuitive way of interaction for users. It can detect more than a hundred different levels of force, and has an accuracy that has to be seen to be believed. And all this can now be done in software, no hardware modifications are necessary. Hundreds of millions of devices currently on the market can make use of the TapForce^TM technology today.

A whole new range of games and apps has just been made possible.

Okay, so what is it doing, exactly?

Most likely, it’s simply reading data from the accelerometer. Hit the device harder, and the accelerometer will respond to more force. That’s actually a fairly clever combination of two sensors – it’s just not the sort of stuff you’d necessarily want to trademark or try to get patented, at least, not if you’re a normal person. (TapForce creators, feel free to explain to us that you’re doing something fancier and I’ll eat my words.)

In fact, part of the reason I suspect that’s how they’re doing this is I’ve been tipped off by a developer who’s already implemented just this. He even uses a piano-style keyboard to show it off.

Sadly, that developer and application is Memo and his MSA Remote application, which was inexplicably blocked from the iTunes store – I think because whoever would have understood the app was on a lunch break or something. See, previously:

Apple Rejects Free iPhone Tool For Artists Because of “Minimal User Functionality”

But as it happens, this is something any mobile device can do that has an accelerometer. I may try something like this on the Android app I’m developing. (No one can reject that, because Google allows any application package to be installed on the device should the user chose to do so. Perish the thought.) Accelerometer data alone is usually not very useful, but combined with touch, it could start to make more sense.

It’s another reason to look forward to MSA Remote, and I do still think that the snafu with Apple will get cleared up at some point. (Unfortunately, what we had on CDM were a lot of rants – perhaps even justified rants – but not necessarily the best way to make the argument to Apple’s store.)
