I have the latest version of GP, a quad midi expression usb adapter and a sustain pedal and the bass library harmonic sound I am attempting to enable when I press the sustain pedal is the harmonic sound from amplesound.net Jaco Bass plugin.
What I would like is create some kind of a configuration to have C0 pressed anytime the sustain pedal is not being used and when pressed momentarily let go of C0 and press C1 and when the sustain pedal is released return to the original setting.
I was initially able to make this work with an organ preset bar on my DMC-122 controller but this is unwieldy and it prevented me from using those bars for controlling Hammond type sounds which is why I wanted to control this feature from the floor instead.
Can anyone advise a configuration that will allow me to do this with my existing hardware?
The MIDI expression pedal does not seem to have an option in its own programming to do this with a sustained pedal which is why I’m hoping there might be some way of coming up with a work around through GP.
