Could someone kindly let me know how to access the hidden banks in the Ketron SD2? The additional sounds are in other banks requiring control change messages (Control Change 00, Value = 1 for Voice bank B, Control Change 00, Value = 10 for Voice Bank B, etc.) and I'm wondering if the cc can be sent from within a sequencer or only from a midi controller keyboard. I have an old Novation midi keyboard controller but I've never used it to send Voice bank messages. It can send Program change messages but it's so old I don't even have the manual anymore and am unsure if that would control voice banks. Perhaps I need to get a new one so a tip re a good midi controller keyboard would also be greatly appreciated.
