Hi Ken,
the same problem sometimes occurs with me on Genos. I don't think it has to do with the keyboard, I mean that MIDI designer does not send proper / complete control. However, when this happens and if I double-tap the iPad screen, the Bank is activated. I have noticed that this problem occurs more often if two Banks are in the same folder. If the Banks are in different folders, then this is not happening. It seems so to me but I can’t claim it because I don’t use the iPad and this connection often. In a live performance, I choose everything directly on the keyboard.
regards, casper
