Hey Scott..thanks for the reminder..

I also have the M-Audio Sono 88..it has some extra features like audio interface, and mic input...but when used as a midi controller with the G70..it is no where as easy to use as the A-33..

I also tried to use the A-33 with the Prelude...not a set up for me...The A-33 can use only the 16 channels and not the extra 3 keyboard parts (realtime)...so it suffers by using the same channel that a sequence would use.(For the most part ..channel 16 stays out of the way of the song playback when selecting a sound you want to play from the A-33)..

Playing a style or MP3 ..with the A-33 playing a sound other than the style channels ..works fine..

There is not the same relation ship between the A-33 and the Prelude....as between the A-33 and the G70.

Prelude is not a GS instrument..
