axoloti

I was just at a 31C3 presentation about 'Axoloti', looks very cool:

http://axoloti.be/

It basically seems like a PureData-like programming environment, but compiles the patch to a firmware to be uploaded to a custom board, the 'Axoloti Core' (http://axoloti.be/axoloti-core/).

The author just put online an IndiGoGo campaign for having the board mass-produced. Looks pretty neat!

The talk is now also online at: https://www.youtube.com/watch?v=UDzzAJWWSFk

I wonder how this custom hardware compares to higher-quality sound cards.

The Axoloti Core uses the ADAU1361 converter from Analog Devices, its ADC and DAC converters are 24 bit and >98 dB SNR. Studio soundcards have better specs, but this is really not a toy in terms of sound quality.

Hi Johannes, welcome to the forum! Very cool stuff - and I certainly didn't mean to imply the custom hardware to be toy-like ;).

I fetched the Axoloti Patcher from github and it seems to compile and run fine - though without the hardware it's kind of hard to really play with of course ;).

Would it make any sense to have a sort of 'emulated mode' in Axoloti Patcher that runs the patch on the 'host' without access to the Axoloti hardware? That'd make a nice 'try before you buy' and may open up some additional possibilities.

Are you also opening up the hardware designs? I see there's some stuff up on https://github.com/JohannesTaelman/axol ... master/pcb but 'note.txt' mentions this is not the final design.

Hi raboof,

Running the generated code natively is certainly on the roadmap, targeting standalone or LV2 plugins. I started the project with developing the embedded part, it 'd be hard to stand out with "another softsynth". Even though I believe it'd be much more than another softsynth since the boundary between the patcher and underlying dsp code is extremely thin without hurting performance. Developing a proof-of-concept quality software backend 'd only take me a few days, but making it cross-platform and testing takes time too.

Final design will be open too, sure.
