Yamaha released new DGX-670; which is closer to PSR-S series, yet, still limited. You can now mute style’s parts, but it looks like you still can’t revoice them. Also, you have 4 sections for each style, but only one intro and one ending. I think that Yamaha is being protective about Genos and PSR-S series, but still wants to give the DGX at least some advantage over previous models and competitors.
