What would you want in your pocket for DJing? How about some key recognition and tracking, key mixing aid, BPM tap — and a flashlight (torch)?

For the DJ who cares about mixing songs together in key and precise tracking of BPM, automatic recognition may just not cut it. One DJ and developer, Pete Simpson, decided to solve that problem – and like a lot of software ideas, initially built that solution for himself. He turns the ever-popular iPhone into a handheld, pocketable companion for DJ sets. I asked Pete to explain not only what the software does, but what it means in his DJ workflow.

Whether you’re obsessive about mixing in key or new to some of these ideas, the answers reveal what this app might do for you, as well as how Pete DJs. (I can also imagine this being useful to remixers tracking a lot of tunes, as well as DJs.) Pete writes:

I’ve recently published an app for the iPhone called DJ Tools. It is something I wrote for myself maybe a year ago, and I use it so much, I thought it might be useful for others. I found automatic key recognition software to be too inaccurate for my needs. D JTechTools did a recent article, and their tests [found] between 20%-40% accuracy for the three products tested. I also note that Beatport and other sites supplying key information seem to use the same automatic software to do so.

Ed.: That’s en excellent DJ TechTools write-up, covering Mixed in Key 5, Rapid Evolution 3, and BeaTunes 3: Key Detection Software Showdown: 2012 Edition

I used to key my own songs with a synth to act like a tuning fork. I wrote an app that does the same, in effect: it will play a chord from any of the 24 major and minor diatonic scales so you can compare with a song you’re listening to. It has a standard tap BPM button. It also displays the other musical keys that will mix with the selected key with the least number of discordant notes (based on the circle of fifths). It gives the standard music notation and the key code notation used by some DJ software. I put a torch on it — bit random I know — but I always forget to bring one, and end up groping around plugging my kit into mixers in the dark. [That's a flashlight, for you fellow Yankees.]

Its a niche app, but I think DJs who are already manually keying their new tracks could find it useful.

So, how does he use it, in practice?

I use tool primarily when I buy music. I will get the tunes into my DJ rig, and play the first tune. I move the track to a part of the music score that has easily identifiable tonal information (a melody line, or bass line) and compare the tune playing to one of the tunes played by hitting the key buttons on the app.

Once I’ve identified the musical key I’ll tap the screen to get an accurate estimate of the song tempo which I use to warp the track.

Once done, I’ll mark the key in my tune’s metadata. Once complete, I don’t need to use the tool (I know the circle of fifths) but if I didn’t I can also use the tool to inform me of harmonic keys that will match the key I’m pressing. For example, I’m spinning a track in A Major, I know the most harmonious key would also be A Major but I would like to shift into another key (I have a lot more songs in other keys, and I’m running out of A Major). So, I press the A Major button and the display informs me that the keys E Major, F Sharp Minor, and D Major all share similar harmonic frequencies and will blend smoothly without disharmony.

That’s about all there is to it. It is a tool for DJs with a basic music training or understanding, who wish to add more depth to their sets by actively considering the keys the tracks are in and mixing coherent keys with it.

The technique sounds great, most decent DJs already do this subconsciously. There are a couple of tutorials on my website that explain the theory and how to use the tool. I’m working on writing more articles but also run a full time job and DJ when I can, so time is precious!

“So,” you say, “I’ve got a … and I want to connect it to a … to make music. How do I do that?”

One strong answer to that question, if you’ve got a Mac, is junXion. Developed by the landmark audio research laboratory STEIM – a hotspot in Amsterdam that for years has been imagining new ways of making music by connecting things to other things – it got a big update recently.

It takes lots of the inputs you might imagine (joysticks, mice, touchscreens, MIDI, OpenSoundControl, audio, Arduino-powered hardware and all of its sensors, and video sensing) and connects it to a lot of the outputs you might imagine (using MIDI or OSC). You can set up rules in between the input and output to make that connection musically meaningful.

OSC input and output wasn’t entirely optimal in past versions; a total rewrite now makes it work with useful OSC sources like the iOS TouchOSC and Lemur apps. You get nifty new Actions, like remote mouse control. You can use a Nintendo Wii “Wiimote”‘s infrared-sesnsing capabilities and vibration support. If you’re using video, you can now support multiple “blobs.” And the whole app promises to run faster and look better, with more help tags in the UI, and added stability.

75 € for the full version. You need Mac OS X 10.5 or later, including the latest 10.7 Lion. (Upgrades for version 4 are free; Lite users can upgrade for 60 €.)

http://steim.org/product/junxion/

Of course, talking about this doesn’t really make much sense; it’s better to see it in action. We have a whole bunch of videos from the folks at STEIM showing features like Wii and joystick control and video sensing from a camera – plus a couple of fascinating demo/tutorials submitted by users.

Let’s watch, shall we?

Via https://vimeo.com/steim/videos

Far from the walls of STEIM, though, intrepid users have concocted their own demos. Here’s a look at controlling Reason with a Wiimote:

Here’s a live performance, also controlled by Wiimote, in the modular live environment AudioMulch. The creator writes:

A basic soundscape in AudioMulch controlled by two Wii remotes via JunXion IV.

Buttons in Wii Remotes control: start and stop buttons, presets of the main mixer, transient parameter of the granulator, frequency of the pulsecomb_1 (processing the drum), a junxion-timer controlling the volume of the granulator.

X-Y-Z accelerators control: 10 harmonics of a frequency generator, parameters of the rissettone

And yes, a camera can be a Theremin:

Got your own solution using junXion – or another tool? We’d love to hear about it.

See also two fine Mac-only tools:
Osculator [Much like junXion, supports nearly anything as an input, adds advanced OSC routing]
ControllerMate [not music-specific, but very powerful modular game input utility]

In fact, what’s largely missing is easy solutions on Windows and Linux, though you can roll your own with a free tool like Pd, which also supports HID, Arduino, video, and the like.

If you’re a Mac user, we’ve got some cheap and free tools for you. And if you’re a Max patcher, you may be surprised with how they were built: they were all exported from Max 6.

This week, we welcome a guest writer developer Dan Nigrin. Amidst some new controversy about Apple and app distribution, here Dan looks at how Apple’s marketplace can indeed be useful to developers using Max 6, the popular graphical patching tool. (Incidentally, the libpd library could work for App Store apps, too, and for mobile on iOS and Android, along with various other tools, so developers now have lots of options for getting their ideas out there.) -PK

CDM has covered the Mac App Store and its impact (or not) on music software quite extensively in the past – see Apple’s App Store May Not Work for Audio Devs; Developers Respond, October 2010, and Six Reasons the Mac App Store Means Little for Music Creation – At Least For Now, January 2011.

But I think a new development may start to change things, at least a little bit. Cycling ‘74’s newly-released Max 6 now makes it possible for standalone apps created with it to be released on the Mac App Store. Previous versions of Max caused some standalone preference files to be written to a Preferences folder on the Mac; believe it or not, this violated an Apple Mac Store rule (an app can only write to very specific locations, not including the Preferences folder – go figure). To Cycling’s credit, they changed the preferences file location starting in Max 6, and so that obstacle has now been removed from getting Max apps in the Store.

I first asked the question about getting Max-built apps in the Mac App Store around the time Apple originally announced it in 2010 – see a thread in the Cycling ’74 forums. Soon after, Oli Larkin tested the waters, and he was the first to discover the above problem with the preference files. After Cycling addressed that, James Howard Young then tackled more minutia required to pass all the approval and validation steps Apple requires, and was the first to successfully get his app live on the store, followed soon after by Oli’s and then my two. We all shared our experience on the above thread, and with each other in private emails.

The apps have done quite well (Audio Plugin Player, below, made it up to #7 on Top Paid Apps in the Music category of the App Store within 48 hours of release), though we are all still experimenting with different price points, support models, etc. — usual App Store growing pains, I would imagine. Here are the apps currently available – note that there may be more, these are just the ones I know about:

Four Apps, Available Now

Defective Records Software (Dan Nigrin)
Audio Plugin Player
Get it on CDM Apps

A lightweight VST and AU instrument plugin host, that allows you to play these instruments using either your mouse, computer keyboard (including support for non-US keyboards), or MIDI device (both hardware and software MIDI devices supported). It has a simple, one-screen interface, without any of the complexity that a DAW takes for a newcomer to get up and running.

Defective Records Software (Dan Nigrin)
General MIDI Player
Get it on CDM Apps

An easy way to turn your Mac into an instrument, using its built-in General MIDI support. You can play these instruments using either your mouse, computer keyboard (including support for non-US keyboards), or MIDI device (both hardware and software MIDI devices supported). It has a simple, one-screen interface.

James Howard Young
TapNTempo
Get it on CDM Apps

A fully featured metronome that offers customizable sounds, real-time tempo tapping, and beat and division capabilities. TapNTempo’s easy-to-use interface includes the best of the traditional metronome, but feature bloating is avoided in favor of simplicity.

Oli Larkin
pMix
Get it on CDM Apps

pMix is a sound design, composition and performance tool that allows you to morph between VST plugin presets using an intuitive graphical interface. 

Presets are represented by coloured balls that are positioned on a 2D plane. The size of each ball and its proximity to the cursor affects the weight of the associated preset in the interpolation.

Morphing between presets often results in the discovery of interesting hybrid sounds. By constraining sound manipulations within a predesigned “interpolation space” complex transitions can be achieved that would otherwise be hard to manage.

pMix can load four VST2 audio plugins. It comes with a suite of specially designed plugins which cover a range of experimental DSP techniques (noise generators, FM synthesis, formant filtering, frequency shifting etc). These plugins can also be used in other VST host applications.

Conclusions, Looking Forward

I made a decision to “start simple” with my App Store apps, compared to for example my Klee or Cyclic. But as you can see, you’re not limited to just simple apps – Oli’s, for instance, is obviously quite complex. So I think that this is just the beginning of what I expect will be many Max apps on the App Store – it makes it possible for the many, many interesting projects developed in Max to reach a much bigger audience that possible before. Just taking a look at the Projects page on the Cycling web site gives a sample of what soon might find its way there.

Perhaps even more exciting is news from Damon Holzborn and Brad Garton of Columbia University, that they are working on a path from Max to iOS apps, and in a way that makes them totally compliant with the iTunes App Store. Really looking forward to this!

We’re looking forward to this, too, so we’ve assembled a special section that shows apps built with Max available on the Mac App Store. We may soon follow this with other tools (Pd, Csound, etc.) if there’s demand. But here are those Max options:

Made with Max, Featured on CDM Apps

Can You Play in the Sandbox?

Ed.: One issue to watch as Apple’s brave, new App Store moves forward is sandboxing requirements. For these Max apps, it shouldn’t necessarily be a problem, but before it appears that we’re endorsing the App Store for all music apps, regardless of purpose, we’re not. A number of Apple developers have raised some concerns about sandboxing and how it’s implemented. They’re worth reading if you’re a developer – and may, in turn, inspire some tweaks from Apple in terms of how this is done. All via Daring Fireball:

Sandboxing and xScope 3.0 [furbo.org]
Fix The Sandbox [Red Sweater]
Sandboxing and Clipstart [Manton Reece]

Here are Dan’s own thoughts on the subject:

No, I’m not concerned about plugin hosting with respect to sandboxing; the sandboxing rules stipulate that you’re allowed to access files on the host system if the user specifies the file in which they are interested via a file dialog. So, in my Audio Plugin Player app, for example, that’s what I do – the user is prompted to pick the plugin they want to use via file dialog (or they can drag and drop it onto the app). That way, I am not breaking any sandbox rules.

Also, one can request additional “entitlements” for one’s application, which allow it to access locations that are not currently “approved” areas within the file system for the app to access. I’d be surprised if requesting an entitlement to access the Plug-Ins folder was not allowed… Ed. That would be, of course, relevant to Apple’s own Logic Pro as a host; despite predictions to the contrary, it appears third party developers should – theoretically – have access to the same entitlements as Apple’s own apps. And if that’s not enough, you can still distribute via other means, including in Mountain Lion, and in contrast to the App Store-only iOS model. -PK

It makes sense that the App Store, with its specific sales model and technical requirements, will suit some applications well and not others. Because you can choose to install apps from other sources, that leaves both users and developer free to choose based on their needs.

Come on – you know that occasionally you want technology to respond when you slap it.

As my sister watched an episode of the television show Quantum Leap, I thoroughly enjoyed watch Dean Stockwell’s character Al give his pocket computer, looking for all the world like a 7″ tablet, little helpful smacks.

SmackTop does that for music. Yes, we hear, ad infinitum, the complaint that laptop musicians simply stare inertly at blue glowing laptops as if checking their email. Now they get to put a little skin in the game, literally. And a version 0.3 update makes this humorous novelty genuinely useful:

Imagine your laptop as a MIDI drum kit. SmackTop is an open-source application for Mac laptops which translates physical motion into MIDI messages. Through real-time analysis of the built-in accelerometer’s output, SmackTop is able to classify four different ‘smacks’. Now you can control your favorite DAW by simply tapping your computer. Slap samples, ping notes and hit record – SmackTop is the MIDI controller you already own.

Try it yourself, free:

http://code.google.com/p/smacktop/ (they miss the obvious name, “SlapTop,” but…)

Got another motion-sensing laptop that’s not a Mac and feel jealous? Maybe someone can port this.

In January, we also expect to catch up in person with developer Raymond Weitekamp and Interface LA, the awesome live performance collective in southern California. Stay tuned.

Slap that laptop, make it free!

Now, a tribute to slaps we love…

You’ve heard all the complaints about laptops onstage. But since there are many arguments for a laptop, why not put all that powerful hardware to use, and make your Mac laptop part of a musically-expressive performance?

Track Master, a Mac-only application available on the Mac App Store (and one of the few serious music offerings we’ve seen there), is a great place to start. It transforms the built-in, multitouch-capable trackpad on recent MacBooks, MacBook Pros, and MacBook Airs into a MIDI controller.

The trackpads on those are actually impressively sensitive and accurate, tracking as many as eleven fingers at once. (So, uh, you can use all of your fingers and invite a friend’s index finger. Or play it by yourself, if you’re the guy who killed Inigo Montoya’s father.)

I’ve been playing with Track Master all morning (uh, yeah, sorry about the blog posts coming late), and it works brilliantly. With mappings to X/Y or scales, you can assign it to any number of instruments and effects. There’s an added bonus, too: by taking over your trackpad for musical use, you don’t risk bumping your trackpad, which makes the QWERTY keyboard more useful as a controller live, too.

If you still want to hide away your laptop, you can also make use of the larger Magic Trackpad hardware.

Full feature list:

Notes Mode

• Play in any key
• Can play with up to 11 fingers
• Chromatic or other scales for easy input
• Key latching, simply press escape while touching the trackpad Ed.: Yeah — that’s important! Keeps it on when you need it. I turned off the option to use “click” for the same feature to avoid accidentally disabling the feature.

X-Y Mode

• Tracks X, Y and finger on off for each number of fingers
• Has assignable control for up to three fingers
• MIDI learn functionality built in to make assigning controls a snap

Interface

• Shows exactly where your fingers are on your trackpad
• Displays which notes are active based on where your presses are

Also, due kudos to Apple: this kind of functionality is exactly the sort of thing an intelligent operating system should provide. Now, can you just please stop breaking plug-in validation, so we’ll love you forever?

Here’s an easy review: if you’ve got a (supported) Mac, get this. Period. US$4.99 well spent.

Track Master at the Mac App Store

Reforge, an iPad audio editor, has gotten a major update with version 2. It’s a ground-up rewrite with a new audio engine, and adds support for Sonoma’s increasingly-popular AudioCopy/AudioPaste API, which provides clipboard functionality for sound between iOS apps.

The novelty of running an audio editor on a tablet is clear. But how would you actually use it, in practice? I asked Tib Horvath, Reforge’s developer, to answer that question. He responds to CDM with some tips. It’s a pitch for his product, of course, but then that’s true if you describe the utility of any tool, and he has some nice ideas about what makes Reforge unique and how you’d work with it in production.

Tib writes:

Let me preamble that with what I believe Reforge is good at: Reforge modifies waveforms nondestructively. So copy, cut, paste, crop. But [it's also good at] also splitting stereo files into two mono files, or a mono file into a faux stereo file.

Then there is automation for volume, stereo balance, stereo widening and low and high pass filters, [as well as] time stretch or pitch (each is independent, but not yet automated).

You get all of this with a feel for actually touching the waveform and directly working with it.

So how does it fit in a production workflow?

1) None of the multitrack [iOS] apps support automation to the extent that Reforge does. So, if you need a sweeping low pass over a drum beat, copy the beat into Reforge [using AudioCopy, if you like], do the adjustments, render the file, and copy it back to where it came from.

2) Some apps work with mono files, but [what if] you have recorded/generated this great sounding stereo loop? Import into Reforge and split it into two mono files to copy over to your multitrack of choice.

3) Some multitrack apps do not work well with loops that just don’t fit. Get the loop into Reforge and make it fit by time stretching it. Clean up pops and other problems at the same time with the automated filter features.

4) Adjust the pitch of a voice recording — for example, if it is off-pitch or if you are looking for a special effect.

5) Podcasters tend to generate long recordings. They can now (since long audio files are only supported with Reforge 2.0) split and splice them. Or import podcasts (any other audio except audiobooks, [since they have DRM applied]) from the [iTunes] Library [accessible in the iPod app], and chop it up for easier digestion or further processing.

All of this is familiar to those who use dedicated audio editors on desktop. While many tools, such as DAWs, incorporate waveform editing, having a dedicated tool can be useful in assisting everyday audio tasks, making the drudgery of dealing with audio files take up less time.

Putting this on a mobile platform has a number of potential benefits:

• Form factor and interface. It’s just easier to pick up a tablet as a representation of your audio and carry it around, show it to others, and edit by touching the interface. You could manage some waveforms over a coffee before heading back to the studio or other workspace, in a way that involves different sorts of interactions than you’d have with a laptop.
• For the all-iOS producer, a tool like Reforge means you can work between other iOS apps more easily, producing sound and music all on the tablet without having to resort to the computer.
• For the person on the go, Reforge of course means the ability to do this editing in the field, as it were, without carrying along a heavier computer.

I do wonder, however, if this kind of easy audio copy-and-paste couldn’t come to desktop environments. Computers and hardware have long borrowed ideas from one another; it seems inevitable that traditional computers and tablets will do the same. And that means, even if you don’t ever touch an iPad, you could see positive benefits in the tools you use.

So, that’s what the developer says — and my speculative take on matters. Are you using Reforge, or other related tools? Let us know how you work.

Also, if you’re an iOS user who doesn’t already use Reforge, and you can tell us something useful about your workflow, I’ve got a promo code for you. Just be sure to leave a real email address in the comment field; only CDM administrators can see it, and we will only use that address for your code.

The tracker is back. Piano rolls and fake multitrack tape turn out not to be the only way to conceptualize how music is put together in digital form. And Renoise is a terrific way to learn a ground-up approach to production, because you get the quick workflow of the tracker without having to sacrifice so many of the “comforts of home” we’re used to in modern DAWs. So we’re pleased to have our Renoise + Indamixx contest going, not only for existing users, but newcomers, too.

Renoise users have one way of evangelizing why they love their tool, which is to show off, as seen in the excellent video above. But what if you’re new to Renoise, or new to trackers in general, and want to experiment? You don’t even need to make a cash investment: you can start to experiment with a relatively full-featured demo version on Mac, Windows, and Linux. The time investment is the likely barrier. So I asked Montreal-based Dac Chartrand of Renoise, who is also the man who keeps tabs on the community, to share his tips. Here’s what he suggests:

1) XRNS files are source code. Find one you like, load it up, press the spacebar and start clicking around. Renoise will happily chug along as you explore each and every facet of the sequencer. When you get bored of clicking, try remixing. Move some notes around, press the escape key and jam on the QWERTY keyboard. Anyone familiar with trackers will tell you that this is how it’s always been done, this is how it always should be, file sharing since the days of Amiga. PRO TIP: Tutorials and Demo Songs are in the Help menu.

2) YouTube is your friend. Go there, type Renoise, watch and learn. Enthusiastic users show off their tunes, some even make "Do It Yourself" tutorials for good measure.

3) Download the "Pattern Command Quick Reference Card" PDF file. This DIY reference was created by a user in the Renoise forums. It’s a cool print out that folds up and sits pretty  on your desk. Pattern Commands are special columns to the right of notes; lets you take sample manipulation to the next level.

PDF: http://paulmerchant.com/downloads/RenoiseReferenceCard2.pdf

4) If you don’t know trackers, then forget everything you learned about other DAW workflows. You must unlearn what you know in order to be a jedi master. For example, other sequencers  have a very strong relation between track and instrument. In Renoise, instruments go anywhere,  tracks are what you make of them. Other sequencers have a timeline, Renoise has patterns that you chain together to make a song. A newbie mistake is to try to make one gigantic pattern.  Instead, make several smaller patterns and sequence them.

5) Documentation. Yup, it’s thee copout tip. But seriously, there are tons of documentation on the Renoise website. Not reading them is kind of stupid.  When all else fails, browse the forums or see if anyone in IRC chat can help.

DOCS: http://tutorials.renoise.com/
FORUMS: http://www.renoise.com/board/
IRC: http://www.renoise.com/community/chat/

Thanks, Dac! Now, I’ll also be working on some stuff for CDM soon, as well, but this should get you going in the meantime.

Must-Have Renoise Utility

Bantai at Renoise also shares (via comments) an excellent tool for sharing your work in Renoise, compressing files, and – aprospos of Dac’s suggestion – inspecting existing XRNS files.

Another tip: you can get the filesize of your song down by up to a factor 10 if you use lossy compressed samples instead of the default 32-bit stereo FLAC file format. I reckon a small filesize wins you bonus points in a tweaker’s compo.

Since Renoise songs are basically ZIP files containing song data and samples, it’s almost trivial to run the extracted contents of the song through OggDrop or a similar application and zip it up again.

It can be easier: I have written a Java tool that takes the work out of your hands and compresses your Renoise XRNS song automatically:

XRNIRipper

(Java geeks, he also writes me: “I’m using vorbis-java lib from xiph.org and a modified version of jFLAC to support Renoise’s custom 32-bit FLACs. There are also several libs included to convert sample and bit rates. Curiously enough, I couldn’t find any other Java apps that encode files to Ogg Vorbis.”)

More Videos, Tips?

It’s a couple of years old and based on an earlier version, but I especially liked this tutorial for demonstrating what the workflow is about:

And if you Renoise-using readers have tips, or if you find a YouTube video you think is especially awesome, please do share. I’ll get back to working on my basic guide.

Mac users luck out when it comes to managing audio files, with exceptional choices like Snapper from AudioEase and the all-powerful AudioFinder, not to mention – if your needs are light – features like Leopard’s QuickLook. Windows users, by contrast, have been mostly left out. But good news: we’ve got a lovely solution for you.

TaggedFrog is a free/donationware utility for Windows XP and Vista that brings some powerful file management facilities. And what’s great here is that it looks dead-simple to use.

Lunar Frog TaggedFrog [Publisher Site, Free Download]

As the name implies, the tool is built around tagging files. Drag and drop files to the iTunes-style Library, then tag them with identifying keywords. That’s it: now the files you need just show up automagically, and you can navigate them by tag. You can also tag directly from a context menu in the Windows Explorer file manager, and if there is keyword metadata in the file itself, TaggedFrog can import those keywords. (For tips on cleaning up that menu, see my previous how-to piece below.)

That’s all nice, but the one essential feature that had been missing is audio file preview. You can thank our friend Brad of Brad Sucks for nagging the developer until it got added:

TaggedFrog adds audio previewing [Brad Sucks Blog]

Important: don’t forget as I did (doh!) that you need an extension to make audio preview work. Look for Croak on the download page. Drag the Croak folder to your [install]/TaggedFrog/extensions, and you’re good to go. An extra “extended information” pane will appear with a play button, optional auto-play, and loop options.

With audio preview, this already-lovely interface is now the perfect tool for managing your audio projects.

Also, what I really like about this approach is that you add only what you need to the library, in ad-hoc fashion. The problem with even the more elegant tools on the Mac OS Finder is that they all tend to assume you want to index huge chunks of your drive, or manage everything from the file system. TaggedFrog by contrast lets you cherry-pick that handful of files you actually need and store metadata about them, while ignoring everything else. You can even move the files when you tag them, so that you actually store them in a logical place instead of … ahem … a random folder in which you happened to leave something.

Of course, if you want actual sample editing and other fancy features in your file utility, you’ll want options like the aforementioned Mac tools. But if you do your editing in other tools anyway and just need to stop losing files, this seems about perfect.

If you start using this and come up with a useful workflow, do let us know. And if you like it, do donate to keep it free.

I know I’ve literally started using this today on my Windows box.

Tips: Fix Windows Explorer, Be Happy

Sound is a wonderful, if invisible thing. To work with these tiny fluctuations in air pressure that make up what we hear, we always work with some sort of software metaphor. So why not make that metaphor pixels – and why not manipulate the visual element directly?

Translating between sound and image is not a new concept in music software. The deepest tool for these functions is unquestionably the Mac-only classic MetaSynth, which sprang from the imagination of Bryce creator and graphic designer Eric Wenger. To me, one of the most appealing features of MetaSynth has always been its filter tool, the one component that allows you to work directly with sound using imagery and painting tools. The core of the tool, however, turns images into a score for synthesis, which opens up powerful features for microtones and the like but can conversely make simply designing sounds more challenging. (Side note: Leopard users, read this re: MetaSynth.)

Photosounder looks like MetaSynth, but it more directly translates between sound and image. It also has a uniquely straightforward interface for precisely adjusting controls and mappings. Put these together, and you can really use Photosounder as an audio tool. That opens up not only experimental techniques, but even makes conventional tasks more accessible.

Photosounder is also under very active development, with recent additions like a lossless mode for better sound fidelity and loop modes. The result is a really compelling looking tool for audio manipulation.

What can you do with these pixel powers over sound? Users have been experimenting and posting some pretty impressive stuff:

• Isolating and removing individual instruments – making this an ideal remixing and sampling tool – using Photoshop
• Making entire tracks from photographs (which, again, was possible with MetaSynth as infamously employed by Aphex Twin, but sounds very different here)
• Processing using Photoshop filters
• Making beats by drawing
• Extreme time processing

Photosounder is currently Windows-only, but Linux and Mac versions are promised. (By the way, I think that’s going to become more commonplace as savvy developers take up cross-platform development tools, toolchains, and frameworks.)

It’s cheap enough to impulse-buy, too, at EUR25 non-commercial or EUR99 commercial.

Photosounder examples (with video)

I hope to get my hands on Photosounder and show off some features with this soon. Thanks to everyone who sent this in! (And yeah, after four or five people I finally get around to mentioning it!)

The best way to see what’s possible: check out the videos. Here’s a selection of my favorites:

Want to load ReCycle REX sample files onto your MPC? Or looking for a better solution for chopping up samples – that is, firing up ReCycle on your screen? Joe Lambert writes in to share his GBP11 Mac utility for the task:

Just a quick note to let you know about a little application I wrote that lets users easily convert chopped Recycle files into Akai MPC program files.

http://apps.steamshift.com/

This essentially allows a producer to chop a breakbeat (or other sample) using their Mac instead of having to use the built-in chopshop and small screen on the sampler itself. It also makes sample CD’s with pre-chopped loops a lot more useful for MPC users.

Unrelated, but he also has a nifty “virtual BCF2000″ utility so you can make use of its control mappings on the road, even when you don’t have the Behringer handy. (Editing in coach class, anyone?)

I’m curious what your REX/MPC workflows are like and if this is helpful.

I certainly have no doubts that this is relevant to some people. I actually spent a good part of yesterday and today hanging out with MPC creator Roger Linn. Among many other conversations, Roger noted his own bemusement at the ongoing popularity of the original MPCs – to say nothing of the MPC as a category in general. You can buy version 3.10 software for the MPC60 from Roger Linn Design. Tom Oberheim’s SCSI adapter for the MPC also came up. From that site:

NOTE: As of March 1, 2009, Tom Oberheim’s Marion Systems has stopped manufacturing the MPC-SCSI due to diminished demand. However, he’ll make another batch if there is enough demand. If you definitely wish to purchase one at for the former price of $300, email us to let us know and we’ll add your name to a waiting list. When the list grows long enough, Tom will make another batch and we’ll contact you.

Yes, just to be clear, we’re talking the MPC60 and the now-defunct SCSI. (While you’re at it, maybe you’d like a new dust case for your Apple III?) Of course, despite allegations that electronic music tech is easily outmoded or disposable, the MPC is doggedly neither. And while I have no personal need for an MPC60, elegant achievement that it was, I find something comforting in that. So I’ll do my own small part – with apologies to Tom and Roger – to call attention to the thing.

Of course, if you do want something new designed by Roger Linn, the LinnDrum II is planned for release later this year. The moment I can talk more about that, I will.
