Hello,
I have made several attempts to fix this issue, I even sent it to apple directly ... No response!
It's very simple
I need to make 12 buttons each of represent the key tunings C-B .
a button should be turned on & off will values of -50/+50
that's the only way I can play world tunings LIVE !
Please help
