I've just dug out my "SRX-04 Symphonique Strings" manual and found on page 6, Patch List (1), at the top left of the list: "Bank Select MSB: 93; LSB: 3". There's also some relevant stuff on p.21 of the XV manual. (MSB is CC00, LSB is CC32, in case you didn't know.) So, you'll need to check out the manuals for your SRX expansion cards. As also mentioned by Linda, the manuals are available at http://www.rolandus.com/mojo/manuals.aspx > I've never messed around with custom messages before > and haven't got a clue where to start. You kind > assistance would be much appreciated. It's pretty easy - like creating a list of controllers in an Event List editor. Full details are on page 218 of the Logic Reference manual. BTW, it seems that Logic can have up to 63 Custom Bank messages per multi-instrument. The 14-bank limit applies only to names of patches. > Ps Which country are you based???!! Australia. About as far away from you as I could possibly get without leaving the planet. Not deliberately, of course! :-) Cheers, Bill
