An example of using expression to control different values from one switch.
Source Audio C4, connected to MC via Neuro Hub (which is just a dumb box providing Host for me, all the work is done on the MC).
My filter sound on the C4 is preset 10, which is recalled from MC using a CC 9 (coz of the usual MIDI 0/1 start numbering thingy!) I want to use my expression pedal to control Filter Frequency, but sometimes Filter Q instead. When I stop using exp pedal I want the Freq and Q to return to their starting values as defined in the C4 preset.
On the C4, I mapped Filter 1 Frequency to CC 2. With my Filter sound loaded on the C4, I noted that the Neuro Desktop editor shows Filter 1 Frequency on screen as a value of 103 and (by sending CC until I found it) I determined that equates to a CC value of 52 - I noted this as my ‘starting value’. I also mapped Filter 1 Q to CC 3, and found that equates to a CC value of 80.
I then set up Exp 2 in my MC bank like this:
So Msg 1 sweeps Filter Freq between my starting value and maximum, and Msg 2 sets it back to my starting value when I stop moving the pedal (regardless of what physical position I left the exp pedal in).
Same for Msg 3&4, but for my Filter Q.
I then setup Preset A like this:
So when I Press to engage Preset A, the sound is engaged, “Filter” starts flashing on the MC6 and exp pedal sweeps Filter Freq. When I stop moving exp pedal, Filter Freq is reset to my starting value. When I press again, the C4 is bypassed, and “Filter” stops flashing on the MC6.
But if I Long Press Preset A, then the sound is engaged, “Filter” starts flashing on the MC6 and exp pedal now sweeps Filter Q. When I stop moving exp pedal, Filter Q is reset to my starting value. When I press again, the C4 is bypassed, and “Filter” stops flashing on the MC6.
Quite pleased with that one
