Better documentation for audio-groups to provide per channel effects.

[dschere]

I have been trying to apply audio effects to individual midi channels without much luck. I tried using the LADSPA documentation but can only apply effects to all channels setting up audio-groups etc. Nothing works.

It would be great if there was a document for hypothetical use case:

channel 0 -> guitar
channel 1 -> bass
channel 9 -> drums

I want to apply a LADSPA effect /usr/lib/ladspa/tap_echo.so applied to midi channel 0
I want a reverb applied to the bass on midi channel 1
No effects for channel 9

What would be the steps including command line setup?

Which LADSPA documentation did you use? This one?

What are the steps you've done so far?
