  • How to change I/O gain on BELA CTAG BEAST?

Any idea how I can control the gain for all 8/16 channels? What's the command in SupperCollider language?

We don't support adjusting the input gain for the CTAG capes, as the AD1938 codec doesn't allow to set that, but you can set the output gain from 0 to -95 dB.

In Supercollider, this option is not exposed so you can only adjust it globally by creating a file /root/.bela/belaconfig and putting this line in it:

CL=-Dx

replacing x wit the desired gain, e.g.:
CL=-D-10 gives you a gain of -10dB.
