RNBO MIDI?

Sindel

Hey all,
I can't seem to get MIDI Input in Bela using RNBO. Has anyone managed to do that?
I'm currently using a Bela Mini, to narrow down the problem.

There is not support for MIDI at the moment, but it shuoldn't be too hard to add. What do you need it for? To control rnbo parameters, those same that you can currently control via analog or digital in?

Sindel

Aha! I knew it!
General usecase would be to use the Bela as a MIDI synthesizer or effect unit. So having support for Note In, and Control Change would be great. In specific I'd like to plug a MIDI keyboard or controller and having it recognized (as PD does).

hmmm that may be a bit more complicated than expected then, I'll have to dig into the rnbo documentation.

Hi all !

I just discovered C74' RNBO implementation on Bela (Mini), delightfully !
Same problem / question as @Sindel : I just would like to have a MIDI control over my patches (from my Octatrack or Korg SQ 64 sequencers).
Any update since April (I don't see anything in the documentation) ?

Best,
Nicolas.

I just tried to add MIDI support, but I cannot test it. See the dev branch of the rnbo.example.bela repo and see if that works. Currently it's reading MIDI from the host computer over USB. If you want to change that to a USB MIDI device connected to Bela, you'll have to change midi.readFrom("hw:0,0,0") to something like midi.readFrom("hw:1,0,0").

Hi Giulio,

Thanks for your answer !
I spent some time on the dev branch (here : https://github.com/giuliomoro/rnbo.example.bela/tree/dev/rnbo/common ) but couldn't find the file you're talking about.
Am I supposed to add this file to the Bela IDE sources ?

I just changed what's needed and... I worked !!
Thanks Giulio !!
(I tried a simple CC modulation from a Korg NanoKontrol, I'll try from the Octatrak in a bit !)
