this was part of the AE modular patch challenge, and partly a project Ive been doing for awhile
(more details in You Tube description)
So the basic idea is quite simple.
The soundplane software is open source, so take the low level soundplane code which has a libusb implementation, port it to ARM, get it working on the BeagleBone Black with Bela.
Bela is a low latency cape designed for audio use, which also provides analog input and output, 0…5v, perfect for AE Modular.
In the end, it was a bit more work than I expected, as there were some complications and bugs which needed resolving - but in the end I got there (thought I wouldn’t at one point )
This approach is great since the CV comes directly from the hi resolution sensors on the Soundplane, not going via midi which would reduce resolution, and increase latency.
(Ive got a prototype for something similar for the Eigenharp but that’s another story )
Im also excited because this same code works on the Bela Salt module, a Eurorack module - so finally I have direct CV control from my Soundplane into my Eurorack.
(I’ll release another demo video once Ive got the code to the next more refined state )
