H9 – Is it possible to [activate] a midi-loaded preset [Q-wah algo] with a midi-expression pedal?
1. From a midi controller, a program change is sent to a H9 which loads a Q-WAH preset, but inactive (bypass) – that I can do already;
2. Pressing the expression pedal – connected to the midi controller – from zero towards max value should: a) activate the wah preset, b) variate the assigned parameters
3. Reverting the expression pedal to 0-10 range would return parameters to zero and deactivate de Q-WAH preset (bypass).
Basically, simulating a Dunlop 95Q wah? This wah has a spring that puts back the pedal in zero position when stepping off and disengages the wah effect with a microswitch.
