I would love to see a Pico setup where the breath pipe and strip controller were changing the FX send volumes up and down while playing. This would be very useful with the samplers and audio units.
For example, if I have reverb or delay as my audio FX send 1 and I want to just have one note or a chord delay for a while, I could just blow into the breath pipe until I wanted it to go back to it's programmed setting. As of right now, the breath pipe and strip controller are pretty much useless on the samplers.
One other idea with the strip controller would be to have it not revert to center when you take your finger off in the midi and audio unit modes. If you have it set to turn up or down a knob in Alchemy the knob would just stay where you leave it when you take your finger off instead of reverting back to the default .
I love my Pico and I can't wait for it to mature into it's potential.
