For this type of situation I have recently created the MIDI Universal Controller tool, or also called MUC.
With MUC you can do much more than with this tool. MUC allows you to dramatically increase the control of your MIDI controller via MIDI routing, and also it allows you to use fewer physical knobs/faders/buttons for everything. It is intended for any physical MIDI controller!
I released it last week, so it’s not very well known yet. You can download and try the demo version…
MUC is probably the best MIDI control tool out there for Renoise today and there probably won’t be anything better than this in the future!
