Do Roland expansion boards have a device ID ?
The reason I bring this up is that EDIROL GSAE editor requires a device ID change to work with the SC-880 module I am told (by edirol).
I don't have an SC-880, but have the VE-GSpro equivalent card and GSAE does not see it properly.
My A70 controller can be changed from 17 up to 32, but that is of no help.
