in that case, if you have the original midi files it would be far easier to play them from the pc or laptop and use the 1000 and 1010 as sound modules, choosing whichever voices you prefer from each.

To play from the 1000 I'm pretty sure the 1010 would need to have a programmable drum map feature, and the midi setup would be relatively more complex.

Besides the 1000 sequencer is only 8 track, so you are merging tracks , or throwing away tracks beyond 8 since you will not be able to play 16 tracks - you really need a gm compatible keyboard.
