Since it seems complicated to be able to assign one actuator to multiple function, I was thinking of the following :
what about a plugin that would setup its own independent midi jack_client and would then be able to
Appear as a midi-controller able to actuate other plugins controls
Receive control input from a physical midi-controller and translate that as multiple CC events to be forwarded to the other plugins
Also translate regular plugin midi input (either note or CC) and forward that to other plugins
This way, one would simply add this plugin to their pedalboard and that would instantly create a fully configurable and chainable virtual midi controller. A single press of the foot on any physical actuator (either on an external midi controler or on the mod itself) could trigger as many CC events as needed and control many other plugins. The same could be obtained using events coming from any instrument or even from the PC (via netjack2).
@falkTX, do you think such a thing could work ?
