>can you explain to a dummy what a midi bank change is? now, now, don't run yerself down! it's simple enough ONCE someone tells you. MIDI program changes tell a MIDI synthesizer to switch to a new sound. (*) However, there are only 128 possible MIDI program changes and a lot of synthesizers have a lot more than 128 sounds. So in these synths, the sounds are organized into Banks. In order to switch between banks, you send a MIDI Bank Change command. You can have up to 128 banks which means Each bank contains (up to) 128 programs. So that means that you can have up to 16384 different sounds. The way it works in practice is that you send a MIDI Bank Change command to select the bank, and then send a MIDI program change command to select the program. It's effortless once you get it down and I don't seem to notice any extra delay in getting the program out... /t (* - Actually some gizmos do other things with the program changes -- for example, lighting units might move to a new scene -- but the idea still holds...) <http://ax.to/fortune>.........a new fortune every minute. <http://FortNY.com>..................Forteans of New York.
