Roland were idiots for not completing this step. A Guitar Mode that you can ONLY play realtime is of no use whatsoever to an arranger player!

Weird thing is, Roland finally introduced the ONE essential feature that would have made it work (multiple non-transposing 'drum' Parts, so strum and picking patterns did not get transposed as you played) but only on Prelude/GW-8 and later, by which time they had already dropped the feature.

You could make a REVOLUTIONARY new arranger from all the great Roland arranger features they have dropped!
