I know this is not the exact question that was asked but I think the answer could be informative and instructive for all.

If we are using a non Yamaha arranger as the style source (korg, Roland, Gem Ketron), and we want to use the Motif as the sound source, could we have the style tracks use the sounds from the Motif?

I know some tweaking would be involved and that would have to be done for each track for each style that we would want to use the Motif sounds. Excluding the time factor, if the styles are tweak that is choosing the desired sounds from the Motif to use with the arranger, could we save the changes as a registration or a style set-up and have those changes recalled at a later date?

Would the same stay true if a new style were to be created from scratch but using the sounds from the Motif?
