The “space bassoon” Eigenharp seems to have landed from another planet. Today, I’ve got good news: it’s bringing alien gifts with it. By next year, both the software and the high-performance protocol the instrument uses will be open source. Taken together with other advancements in the open source community and with protocols like OSC, that could mean we’re at the vanguard of a golden age for more open, more intelligent, more expressive digital instruments.

Genuinely new music controllers made available commercially don’t come along very often. So this week’s news of a strange but wonderful-looking instrument shaped like a bassoon with customizable key controls turned many heads. With high-resolution, high-frequency data and reliance on the computer for everything from sound generation to mapping the keys to different tunings, the computer connection matters. Eigenharp’s chairman, John Lambert, sets the record straight for CDM on the software, the way it talks to your computer and other gear, and how open the tools and protocol will be.

I’ll be talking more with John next week, but I want to bring you this news now. Part of blogging means that you don’t hold back – you share that first reaction and then learn more. I’m pleased to say I was dead wrong on the Eigenharp. What looked on the spec sheet like MIDI-only communication and proprietary software turns out to be just the opposite. Sometimes, being wrong is great. Here are all the details:

What protocol do the instruments use?

The instruments talk to their base station by a dedicated, high speed, differential, transformer-coupled, error-correcting digital protocol designed (and tested) for use in noisy stage environments by ourselves. The wire used is a 4 core, standard star quad mic cable and can be up to 40M long. The base station then talks to the control software running on the host PC (Mac at the moment) via a dedicated protocol over USB2. In the host system, the native protocol used between agents (our software components) is a network protocol called Eigentalk. This can run over Ethernet wires (with slightly increased latencies due to some smart jitter buffering we do). We will be making this public and freely available (when we open-source our main software) in Febuary next year. There is an open API, to be published at the same time, for our equivalent of AU’s or VST’s, hosted in our software, EigenD. This is rather richer than the AU and VST API’s, for reasons connected with the expressiveness and configure-ability (is that a word?) of our system. A couple of interesting AU vendors are looking at producing native EigenD instruments at the moment, and I think there will be many more in time. We try to avoid MIDI wherever possible as it has so many serious performance limitations.

Had you considered OSC?

We did have a look at OSC but there are a bunch of things that our protocol does that OSC didn’t (not least of which, for example, is clock syncronisation for jitter removal, utterly vital over ethernet for live performance) so we decided to grow our own and release it. Absolutely no reason whatsoever that we can’t interoperate fuly with it though, I suspect that an OSC EigenD Agent will probably come quite soon after the open source release.

Ed.: Actually, with OSC (OpenSoundControl) moving increasingly toward broader input and assimilating other standards, I can easily imagine that a future implementation of OSC could begin to implement these features. More on both protocols in the coming months. -PK

Is it possible to use this as a controller for MIDI hardware? MIDI software?

Yes, EigenD has in and out MIDI gateway programs. The incoming [MIDI] is mainly used for pedalboards at the moment (to control scale, key, tempo, etc.), although there is no reason you couldn’t use a midi keyboard to play notes. We’re using the MIDI out to do a wide variety of things, including playing MIDI sound modules, and controlling video DJ software and lighting systems. There is a huge reduction in effective bandwidth when ‘downsampling’ to MIDI, but for a lot of things it still works very well. And of course, the AU and VST standards (which we fully support) are a kind of MIDI interface.

Is it possible to access its native protocol for custom software / Max-Pd patches and the like?

Well, we’re open sourcing the whole thing early next year, and I think there’ll be a lot of work done to glue all sorts of external stuff in then. Max/MSP has attracted a lot of interest in this area. The whole of EigenD is kind of built for this really. We’re an Open Source company: my main personal desktop is Linux and I have a strong personal commitment to open standards. I offer a number of ‘programming bounties’ for Linux improvements on my personal website at http://johnhenrylambert.com.

Tell us more about open-sourcing the software. What tools did you use to build the software.

It’s written in a mixture of C++ and Python. It’s quite scary code, but very clean and pretty, with little ‘cruft’. I think the open source community are going to have fun with it. Its a big system too, 8 years of R&D in one huge release. I don’t think that there’s been anything quite like this open sourced before in the music world – it is a bit as if Logic or Ableton were GPL’d tomorrow.

Thanks, John! Stay tuned for more details, and let me know if you have specific questions for the creators.

I don’t know if it’s “the most revolutionary new musical instrument of the last 60 years,” but let’s be clear on one thing: the Eigenharp Alpha is utterly, beautifully insane. It combines breath and finger input in a bassoon form factor, but with quite a lot more physical control, a computer connection, and no internal sound source of its own. The breath input comes from a crooked tube as on a bassoon, with finger input in a touch strip, a fretted, light-up keyboard, and keys that have their own various forms of expression. Launched yesterday in London, the Eingenharp is getting a lot of attention. (And yes, some of you spotted signs of its launch all the way back in June, to which I say – I’m sorry I’m so late to the party.)

From BBC: Do you drum it, strum it or stroke it?

I hope to speak to the creators soon. Already, I see some indications that there are equal parts genius and madness here. The controller itself, even in the bizarre bassoon form factor, has an extraordinary amount of control, with high-resolution keys, percussion keys, elaborate control arrangements that can adjust tone or record samples, and extremely precise breath and touch. At £3,950, many computer musicians accused of “knob twiddling” by the creators probably won’t be able to afford the top-of-the-line model, but I do believe an instrument like this can easily, fairly cost this much, it’s a cost reasonable for musical instruments – and there is a £349 “Pico” edition for mortals.

There’s some madness, too, however. For the “instrument of the future,” the creators appear to have chosen MIDI, via USB, in place of a modern control protocol. Then, they plug the instrument into proprietary Mac software. (A Windows version is expected early next year.) There are software models of a Cello, a Clarinet, and a Synth, but there are also gigs of samples oddly loaded into SoundFont format. Given the futuristic ambitions and the sky-high price, closed software and antiquated I/O seem puzzling to me. I’m also skeptical of the approach here of piling on as many controllers as possible.

CORRECTION – CORRECTION! Yes, indeed – proprietary software and the limitations of MIDI wouldn’t make any sense – and apparently the creators agree. So the software will be open sourced, as will their custom-designed protocol. I’ve got all the details – required reading for anyone working on expressive instruments.

But don’t get me wrong. I think this fascinatingly bizarre instrument is worth exploring. The hardware design looks exceptionally luxurious, and there is some genuine design innovation in the controller the likes of which we’ve never seen in an instrument beyond a prototype or two.

Oh, and yes, I already want the Pico – and I think the Pico’s fewer controls may actually make more sense.

Basic specs:

Video of the key action, among others collected on YouTube:

The “Alpha,” the flagship:

• 120 keys, plus 12 percussion keys. (Wait — 120? Yes, you read that right.)
• Two strip controllers, one on each side.
• Breath pipe and mouthpiece.
• 11-bit resolution (2048 values) in the keys and strip controllers, 12-bit resolution (4098 values) for breath.
• Internal audio interface with mic pre, converters, and headphone out – so you need to carry this and a computer, but not this, a computer, and an audio interface.
• A “Base Station” with inputs for expression pedals and foot switches, which also contains the USB connection. This connects to a floor spike on which the instrument rests.

The Pico:

• 22 keys (18 for playing, four mode switches).
• Keys work via direct pressure and lateral pressure in both directions, as on the Alpha.
• Breath pipe.
• Strip controller.
• Same resolution: 11-bit keys, 12-bit breath.
• £349.

To be honest, I’m quite a lot more interested in the Pico, not because I think cheaper is better, but because I’m curious whether you can’t be just as expressive with the more limited set of controls as with the kitchen sink approach of its big brother. After all, 22 keys is roughly the number you’d find on most reed instruments, including the Bassoon. True, the piano has 88 keys, but it also doesn’t really have anything else – and it’s able to have so many because of its form factor.

In fact, I’m sorry, but I love the Pico. It looks friendly, it looks portable, it isn’t terrifying-looking like the Alpha, and it seems it’d be more at home in a variety of musical venues than the Alpha. Sometimes less is more. Let’s see if I prove to be correct.

The software, though I hope you could also customize your own software rig using the MIDI input:

• Modular, allowing the routing of control inputs, sound sources and samples, loopers, and synthesis and effects.
• SoundFont oscillator.
• Physical models of the clarinet, cello.
• AU host for adding your own plug-ins. (And yes, this is where I think you’ll have the most fun.
• A system for triggering events, takes, key, and mapping scale.
• An interactive arrangement system for step sequencing.
• Oddly, an extensive Steinway D multi-sample. On the other hand, for years we’ve all have been playing bassoon and other reed samples on the keyboard, and in organ form for centuries, so now the reed instrument gets its revenge.

The instrument’s creator, John Lambert, repeats the maxim heard at new instrument design conferences: “We’ve got pretty fed up with watching people twiddle knobs on stage.” Naturally, that means… turning to the Bassoonist, that sex icon of the orchestra? I’ll run with it.

One other tidbit from that article:

He says there is one high-profile musician who is about to take delivery of an Eigenharp, but won’t give any names.

Yeah, Herbie Hancock, we know it’s you. (Okay, they are an English company, so maybe it’s an English celeb, but really the question is whether Herbie is who they mean, or whether he’s filling out the pre-order as we speak. He’s like what we would all be like if we had a budget.)

Anyway, consider this a first look. I hope to get closer to the actual instrument soon.
