[Uses & Ideas] Select Exp Message

Morningstar Gear Planning Strategies

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 :slight_smile:

I love this. Is there any way to toggle back to Filter Freq after selecting Filter Q? Maybe the new shift feature could be useful.

Not needed - in my example if you long press then you’re controlling Q, and when the preset is next engaged with a Press it’s selecting the exp messages controlling Freq (which is how I want it).

Will be interested to see what can be done with shift in this example though for sure!
