May My "Preset" made you misunderstood...sorry.
[My connection environment]
I connect iPhone to mac midi-patch-bay to FractalAudio AxeFX2 Guitar DSP.
MIDI channel is 1.
More simple question.
My MD's [P1] button can send program change 1 to Axefx2.
How can I get [P1] button program change 11,21,31,41,,,,with [up] button?
I know max value is 128,Next option is BANK.
Thanks your supports!
