What if a gaping product hole for musicians were filled by a game company instead of a musical instruments company? There’s no need to imagine: pick up the new Rock Band 3 keyboard, and you’ll see what I mean.

Consider: most sub-$100 and compact keyboards have dumped 5-PIN MIDI DIN ports in favor of USB only – little comfort if you want to plug a keyboard into that DIY sound module or eBay treasure. (Alesis’ QS25 is one exception, but even a $150 M-Audio Oxygen is USB-only.)

And keytars? Fuggedaboutit. Strap-on keyboards or keytars are a great way to play keyboard lines, but they’ve tended to be freakin’ huge. They really do feel like strapping a full-sized keyboard on your shoulder, which can kill the joy of playing them. And the current “entry-level” model, Roland’s Lucina AX-09, has a street of US$600 or more. eBay bidders have made used items similarly pricey.

So, forget for a second that a game is involved. What if I told you you could get a cute, light little keyboard with MIDI DIN, intelligent MIDI mappings, and two great-feeling synth action octaves, all in a strap-on form factor with battery power, for $80?

Yeah. That’s what I thought. So whether you’re a hardened gamer or just looking for a nice, mobile keyboard controller, here’s an in-depth look at how MIDI works on the new Rock Band 3 Wireless Keyboard Controller – forever to be known to everyone outside Harmonix and Mad Catz as “the Rock Band keytar.”

The Hardware, Impressions

Hardware specs:

• 25 velocity-sensitive keys. (Velocity already gives a leg up over some stuff you can get on eBay. No aftertouch, though.)
• TRS port for stomp or expression pedals. (Right now, that means the bass drum pedal, until we figure out a DIY solution. It uses a little 3.5mm jack; working on finding out voltage specs.)
• 1-axis touch strip which maps to modulation and pitch.
• 5-pin MIDI DIN port.
• Xbox 360 (or PS3) game pad, wireless Xbox operation. (For wireless MIDI, you’re on your own.)
• Three AA batteries. (No external power.)
• Optional stand accessory. (This looks cute; I didn’t pick it up yesterday but may yet.)
• 4.6 lbs.

US$80 street, and also available bundled with the Rock Band 3 game.

I’ve handled a lot of “shoulder-mount keyboards,” and the simple reality is, a lot of them have pretty awful ergonomics. The Rock Band keyboard is about the best I’ve handled. It’s light enough that you can hold it in one hand, and compact enough that it’s about the width of a typical adult waist. That means it actually feels like a keytar sized to be played as a keytar.

The keyboard action is just a basic, unweighted synth action, but feels solid enough, and velocity response is consistent. I have to admit: I was very surprised by the quality of the keyboard. You could easily put this alongside so-called “pro” unweighted keyboards in the sub-$200 range and, blindfolded, no one would ever guess this was a game keyboard. I have no idea who built the action (it’s labeled “made in China”), but there would be no shame whatsoever in using it.

One oddity: F3, C4, and F4 each have raised ridges on the left-hand side of the keys, in order to delineate the keyboard’s five zones for gameplay. With proper keyboard technique, though, you won’t even feel them, since the pads of your fingers will hit the middle of the keys. (That is, unless you have larger fingers.)

You also get a standard set of game controllers, and everything either sends a MIDI message or is used to toggle features on the keyboard. Not a button goes to waste.

The touchpad on the neck is probably the weak spot of the design. It’s usable, and conveniently located, but its response is pretty hard to control exactly. It’s also hard to hold down the overdrive button while using it, which is the only way to get to pitch. Then again, your left hand is likely busy holding the keyboard, anyway, just as on all keytars, so a pedal seems the better solution for anything really expressive. I’ll see how I adjust to it over time, though.

MIDI Mapping

As with the guitar, operation is simple: plug in a MIDI cable.

Yeah, okay. There is something to be said for old-fashioned MIDI, huh?

Once you’ve plugged in, you get some surprisingly robust MIDI implementation:

Keyboard: 25 keys transmit normally, with velocity. (No aftertouch. I’m glad we get velocity.)

In drum mode, the keyboard transmits General MIDI drum parts, which is, of course, handy for playing drum patches. (It’s also handy for confusing the hell out of you if you didn’t know that’s what it did.)

Touch controller: 1-axis modulation. Hold down the “Overdrive” button, and while that button is held, it sends pitch bend – which makes pitch bend nearly unusable. (Too bad they didn’t just make the Overdrive button a straight toggle.) Works well enough for Modulation, though.

Octave: Octave up and down shift uses the X and B keys (on Xbox, or the left and right action keys), just as on the guitar – and just as on the guitar, you get four up, four down. Octave feedback is available on the LEDs.

Program change: Top and bottom action keys increment or decrement, respectively, program change. (Y and A on Xbox.)

D-pad buttons: As on the guitar, these toggle functions, though for the keyboard all four are mapped instead of three. Up turns on and off drum mapping, right changes the pedal to foot controller, down changes pedal to channel volume, and left changes the pedal to expression.

Transport controls: The Back, Guide, and Start buttons on the Xbox gamepad correspond to Stop, Continue, and Start MIDI messages, respectively – so if you’re tracking your next Rock Band Network song in Reaper, you can control your takes right from the keyboard.

Pedals: There’s one pedal port on the side. More on how to use this soon; I haven’t yet tried it. It’s a 3.5mm jack, but I have to find out the voltage. Stomp should work fine with a standard Rock Band drum pedal, and in the default mode, you can use that for a damper pedal. For expression, you need something that sends analog voltage.

Panic: Press the Back, Guide, and Start buttons simultaneously to switch all notes off. (Curiously, this appears not to be the same as on the guitar, but I can only test the keyboard to know for sure.)

MIDI channel: 1. Always. It’s always MIDI channel 1.

Note that there is no accelerometer output from the keyboard. Too bad; that would have been fun (and likely more useful than the two-fingered salute you have to do to get pitch bend from the touch strip). In fact, this sounds like a ripe opportunity for a little hack – maybe a strap-on board that transmits accelerometer and MIDI via Bluetooth.

Applications

Bottom line is, this thing is a joy for controlling computer synths or hardware, and may have just become my portable keyboard of choice, just because it’s fun to strap on. Of course, if you don’t care about the “keytar” form factor, any number of inexpensive keyboards will give you real pitch and mod wheels and some knobs. But if you want to play a keytar, this game controller has become, bizarrely, a must-buy.

As we find out more about the pedals, I’ll share that. In the meantime, enjoy.

Since the very first Guitar Hero game, musicians have found ways of converting game music controllers into genuine music controllers, through various hacks and tricks. But now, no hackery is needed: Rock Band 3′s new “Pro” controllers ship with actual MIDI DIN ports on the back. With the help of Harmonix, we get to look inside how that MIDI implementation works.

The Rock Band 3 Fender Mustang Pro-Guitar, designed as a collaboration between Harmonix and Mad Catz and manufactured by the latter, isn’t exactly a full-blown MIDI guitar. It has strings, but in place of fretting those strings, you instead use 102 fret buttons. (Stay tuned for details of the Squier Strat for RB3, which will be both – actual strings over the frets.)

Non-guitarists won’t mind the buttons: there’s no need to build up callouses. And the frets are located in the right place, so if you do know how to fret a guitar, you’ll find it usable. The other big upshot is price: with a street price of US$150, the Mustang is on the high end of game controller, but very much the low end of things that can simulate a guitar with MIDI.

I don’t yet have a Mustang on-hand — I’m hoping I can find a real guitarists to give one a full play test when it ships late in November. But I can describe how MIDI works on the device.

The hardware:

• Six actual strings sense velocity. (As you can see in the picture, they stop before they get to the fretboard, covering only the distance needed to allow you to strum them.)
• 102 buttons stand in for frets (17 frets, 6 buttons per fret)
• Power from three AA batteries
• 6.3 lbs
• Tilt sensor
• Xbox 360 game pad
• TRS port for stomp, expression pedal input. (Stomp pedals from the game will work; for expression pedals, we’ll need to do a hack or DIY solution.)

Here’s the pleasant surprise: just about everything onboard is mapped to MIDI, including even the game pad and tilt sensor. And there are even two play modes for additional flexibility when you’re working with MIDI.

Thanks to that 5-pin MIDI DIN port, you can connect the guitar to any computer or synth – even a post-MIDI vintage synth found on eBay. (No USB MIDI is provided, but a lot of audio interfaces and keyboards give you a MIDI in port “for free.”)

Configuration instructions: step one, turn it on. (The PS3 and Wii version will have an actual power switch; on Xbox 360, you have to hold down the Guide button, just as on other Xbox controllers.) Step two, plug in a MIDI cable (the one with 5 pins that we’ve been using for over a quarter century). Step three — there is no step three. Turn it on, plug, and go.

MIDI implementation

Octave: Increment and decrement octave are the left and right action buttons (X and B on Xbox).

Program change: Increment and decrement are the top and bottom action buttons (that’s Y and A on Xbox). Transmits on channels 1-6. No, really. There’s a program change message implemented on this thing. The default is 28, the patch for a clean electric guitar in General MIDI.

D-pad buttons switch functions for the pedal, from foot controller to channel volume to expression.

Pedals: Connect an analog pedal, and you can use continuous expression or volume. Connect a digital stomp (that is, one that’s either on or off, like the bass drum pedal), and you send a damper pedal / sustain message.

Panic: Mercifully, there’s an all notes off command issued if you press the Xbox Back, Start, and D-Pad right at the same time. (Hmmm – feels like ctrl-alt-del.)

MIDI channel: By default, the guitar transmits on channels 1-6 — that’s in order to transmit strings separately. Each of the six strings is a different channel.

Accelerometer transmits Modulation on the X axis, Expression on the Y axis, and Pitch Bend on the Z axis, and each can be toggled independently with shift (the Start key) + B, A, and X, respectively. (That’s a good thing, as controlling all three at once would be a little messy.)

Frets and strings: Here’s the tricky part, because you’re strumming something rather than playing a MIDI keyboard. There are two modes:

• “Strum mode.” Hold a fret, then strum the string. The note is sent when – and only when – you strum. The pitch is set by whichever fret is closest. That note is held until you change a fret.
• “Synth mode.” Strumming a string or changing frets will generate a note – meaning, if you like, you can use that fretboard as a 102-key keyboard. (Microtonal fans, go nuts.) Here’s the odd part, though – you need the strum to set velocity, so whichever strum you’ve last strummed is your current velocity. While it’s called “synth” mode, this is the only mode that allows hammer-ons and pull-offs.

We’re going to need to get the actual guitar and shoot some video before that really makes sense. But you get the idea.

You can adjust pitch up and down 4 octaves in either direction.

LED feedback gives you information on what’s toggled and what isn’t, though my guess is you’ll just listen rather than try to squint at the LEDs.

Want Real Strings?

If those buttons look unappealing to you, Rock Band 3 will have an alternative with real strings, the Squier Stratocaster.

In many ways, the Squier is more interesting – especially to actual guitarists, and not just people looking for a new way to fiddle with soft synths. With real strings, it ceases to be a toy, and while pricing and availability haven’t yet been announced, it’s likely to be the cheapest MIDI guitar solution out there.

I’ve confirmed that the MIDI implementation on the Squier will be similar to the Fender Mustang Pro – same channels and messages. It lacks the pedal inputs.

Engadget did a nice hands-on preview of the Strat, with photos and video.

Likely applications

With both “Synth” and “Strum” modes possible, I think Harmonix and Mad Catz may have a hit here. For someone who isn’t quite ready to commit to a MIDI guitar yet but just wants an alternative way to track some MIDI lines, it’s hard to beat basic input for $150, with frets in the right place instead of a piano keyboard. For other applications, I can imagine having some real fun – with the accelerometer and “Synth Mode,” the guitar becomes a very viable, absurdly cheap, velocity-sensitive controller for strange new synths and other creations.

It’s probably some of those oddball applications that will appeal most, as I suspect real guitarists will hold out for the stringed-fret Squier, leaving the buttons to the rest of us.

Beyond MIDI: These are wireless Xbox 360 controllers, too, so if you have any tool that can talk to Xbox controllers on PC, you should theoretically be able to rig up something wireless that doesn’t involve MIDI cabling. But I like the ability to plug into hardware synths with MIDI, no computer necessary, too – and as I say, those MIDI ports are often “free” on gear you already have plugged into your computer.

Stay tuned for when this ships.

Hopefully that gives you an idea whether you want to pre-order this sucker. Knock yourself out.

Games really are reshaping music. Despite their relatively simple gameplay, the Guitar Hero and Rock Band franchises originated by developer Harmonix are stimulating interest in real music making. It’s no accident that you can walk into a Best Buy and, next to aisles of video games, find a growing selection of serious musical instruments and technology.

These titles are also stimulating interest in music and artists and producing a new distribution outlet, at a time when the distribution picture for music can seem bleak. But until now, that outlet has been limited to big acts, big tracks, and big deals with big labels. It has only promoted music you already know, not the discovery of new music. Rock Band Network could change all that.

We took a detailed look in August at how Rock Band Network worked technically, and how authoring a song for RBN could give you the same level of gameplay and choreographed graphics that the official Rock Band tracks get. But now here’s the big news: at long last, RBN is opening to the general public, starting with an open beta for artists and play-testers.

What it is: Rock Band Network is a new set of authoring tools (built around Reaper), a submission process (built around Microsoft’s Xbox 360 XNA Ceators Club), and an upcoming store to host indie tracks called the Rock Band Network Music Store.

What it costs: Rock Band Network membership is free, but you’ll need a $99/year XNA Creators’ Club Premium account to submit or test music.

What you’ll need: To author titles, you need an Xbox 360, a copy of the Reaper software, a set of free plug-ins for Reaper for RBN, the XNA account, and either a Windows PC or Mac. (You’ll need Windows, either virtualized or on another machine, in order to actually load the tracks for testing, but you can author on either; see below for more.)

What it gets you (as an artist): If you make it through the peer-reviewed submission process, you stand to set your own pricing and receive 30% royalties (retail, excluding tax) on everything you sell.

What it gets you (as a peer reviewer): With the XNA Creators’ Club membership, you can play as many tracks as you want without any additional charge, in exchange for your feedback. Tired: squeezing into sweaty, overcrowded bars at CMJ and South by Southwest to hear new acts. Wired: Scouting for new acts on your cough with your Xbox 360. And that could make a nice community of music, depending on how this evolves.

Where the tracks will be distributed: Anyone with a copy of Rock Band 2 (and presumably future versions of Rock Band) can play your tracks. Releases will initially debut on the Xbox 360 store for 30 days. A “selection” of tracks will also appear on the PS3 and Wii stores after that. (The approved songs will stay on the RBN Store on Xbox 360, regardless.)

When does all of this happen? The open beta launches today for peer reviewers and artists. The store is due, um, “real soon now.” (No specific date yet.) The game itself is ready to go, at least on Xbox 360: a patch introduced way back in September added the ability to play RBN tracks.

CDM Talks to Harmonix

John Drake, Program Manager for Rock Band Network, took some time out to answer my questions on the eve of launch.

CDM: What will the Rock Band Network Store look like? Where will you get access to it? Will it be a similar store on the PS3 and Wii?

John: The RBN store will run in parallel to the existing Harmonix DLC store, and will be in the same menu location within Rock Band 2. The RBN store has more info about each song than our existing DLC store does, and it has more ways to discover new music: you can search by subgenre, album, country of origin, record label, even the author of the song.

The PS3 store will be very similar to the Xbox 360 store. Details of the Wii RBN presence are still being worked out.

Ed. note: It’s especially nice to see the RBN store on equal footing. I had high hopes for the XNA-produced games on Xbox Live, but those titles aren’t displayed or listed in exactly the same way, which I think has hurt the initiative a bit.

CDM: In addition to the XNA Premium subscription, you still need Windows to support testing your own tracks, yes? Do you need a Windows PC to be a playtester?

John: You need to run Windows in order to transfer song files to the Xbox 360, because we use Games for Windows Live to manage the transfer. We have informally tested running Windows on a Mac on a number of virtual machines, as well as BootCamp, and most of them work perfectly for transferring files.

Ed.: I can add, a number of the Harmonix guys are Mac fans, so you can believe they tried the virtualization approach!

CDM: Since we last talked, there has been a private beta. Were there any additional improvements / changes since our August conversation? What kind of feedback have you gotten?

John: The closed beta has been absolutely invaluable to help us shape the experience for the new members just now joining the program. We’ve cleaned up and organized the documents section of the website, added a great deal of new information, clarified policies for submitting songs, and generally made sure that the pipeline is running smoothly. None of the major processes are any different than initially designed, but we have changed a million small details to make it better.

It’s important to note that the members that have been in the beta have been absolutely extraordinary: patient, intelligent, hard working, thoughtful, and helpful to each other as they worked through the inevitable issues that cropped up as we readied the site for launch.

CDM: Have any currently-available tracks come through the private beta process? (Jonathan Coulton’s?)

John: We currently have nearly 40 approved tracks, including tracks by the inimitable JoCo, and a bunch more up for playtesting and peer review. We’re expecting even more great content to go up for testing in the next few days, and we’re excited for people to join our playtesting ranks to get even more songs through the pipeline!

CDM: I see TuneCore is offering track preparation services. Have you seen similar offerings begin to appear? (For some of us, doing the authoring may actually be satisfying – we’re weird that way!)

John: There’s a great variety of services cropping up from authoring houses offering with different programs to create songs for bands. These range from straight, up-front fee structures to a $0 down, pay us out of your royalties deal. It’s really exciting to see how different groups are responding!

*PS, I’m with you on the satisfaction of authoring. I’ve been working with my band to put our whole last and current record (17 songs in total) up for RBN. It’s a lot of work, but it’s super rewarding to get involved in the process! And it’s really doable if you’re used to making music as a passion!

CDM: Outside RBN, are these tools beginning to be used on Harmonix’s own tracks? (I believe that was in the works when we last spoke.)

John: It was always the intention that the tools we developed for the Rock Band Network would be integrated internally at Harmonix and that has begun to happen. With the industry leading amount of content we produce (over 1000 songs and counting) anything that makes the job of our unparalleled Audio Team easier is welcome, and in most cases the Rock Band specific tools were built by members of the Audio Team themselves!

CDM: Okay, enough of the nit-picky details… what’s it mean for you that you finally get to take this to public beta? Now with a few months more perspective on it, what do you think this will mean for musicians to get on this platform, revenue aside?

John: As our Senior Producer Matthew Nordhaus said about Rock Band Network, “It completes me.” We’re already thrilled with the community working within RBN and we’re hopeful to see a lot more great content and enthusiastic playtesters signing up at Creators.RockBand.com now that we’re open!

Additionally, we’re really proud of our teams here at Harmonix and MTV Games, who have designed a really smart way of getting great music into the hands of fans. Empowering musical groups of all sizes and genres to be able to post their own content for sale is really a dream come true at Harmonix. Adding the great variety of music for our passionate fanbase only makes it that much sweeter. We’ll be even more excited when the store turns on and those first tracks sell!

Go Check it Out

I hope to help document both how artists are using RBN and the technical process for doing this yourself over the coming weeks. In the meantime, you can hop on the beta yourself if you’re interested:

GamePad Companion (US$15 shareware)

Of course, the nice thing here is that the basic steps apply to other controllers, just in case Rock Band doesn’t float your boat (or rock your socks, or whatever).

I ended up choosing kick, snare, two toms and one cymbal, since the other cymbal I wanted was in a inactive area of the keyboard. I re-mapped the keys in GPC, switched back to GB and gave it a try. Success! Samples were triggered correctly, the fast key repeat rate didn’t cause any problems, and latency was basically nil.

More good news: Bill has updated the post with information on Xbox 360 controller possibilities. Generic Xbox controllers work just find via the Wireless Gaming Receiver. No word yet on the Rock Band controllers, though, and I think they do a little more than the standard controllers. Anyone got an Xbox 360 and a Mac who can tell us if it works?
