On the latest firmware there is the following description: Some words to the "bb" (BankButton) variant: it uses two bank buttons instead of the four bank switches on RB2, RB3. Two additional buttons on RB0 and RB1 enables you to send double note events (great for controlling programs like Cubase, Logic, Cakewalk via MIDI Remote). My question is if there is a problem if I combine in one button the RB2 and RB0 and in onother one the RB3 and RB1? I already made the connections and it seems it doesnt hurts. But if there is a possible mulfanction arising from that I would like to know. Best Regards Dimitris
