Hello,
Thank you for using Eventide! It sounds like you are really making use of the TimeFactor's MIDI features.
The knobs can be set to transmit MIDI CC values, perhaps assigning an aux switch to control a knob would achieve what you are looking for. There is a System menu called "KnobLock" which prevents the onboard knobs from changing the sound but still keeps them transmitting MIDI.
We will look into the issues you described. It may be possible to address these things in a future software update.
Best,
Alan
