Sound Canvas VA uses four different banks (maps) of sound, to make use of the SC-55 map, the SC-88 map, the SC-88Pro map, and the SC-8820 map.
 
Bank Select is done with Controller 32, but only bank 0 is available, which is whatever default map I have SCVA set to. But to access the other banks, I need banks 1, 2, 3 and 4 as well.  This is necessary, as I've used sounds from the SC-55 map AND the SC-88 map in the same song.
 
Is there a reason SONAR (and Music Creator, too) doesn't work with this?

Hi. Could you share the solution, in case someone else has the same issue?
All the best.

There really isn't a solution. :-)  I was just not paying attention to myself, entering data in the Event List incorrectly.  

Ok
