Actually there's no need for them to contract out for better drums. Yamaha already makes better kits.... They're on the Motif XS series. Again..., it's yet another repeat of Yamaha's refusal to go the other way with their sounds. The many very impressive signature voices that make the Yamaha arranger line so popular were good enough to add to the Motif line (but Yamaha changed some of the names so the synths wouldn't have the PSR association--gotta protect their sales I guess), but again.., Yamaha will not go the other way. Given the Tyros is their top (very expensive arranger-costing more than their top 88 key workstation), the least Yamaha could do is give the Tyros some of the kits from the XS line... I'll tell ya what.., those styles would freaking jump out of the keyboard if they were being driven by Motif XS drum kits.
