Irregardless, the ability to easily save a given MusicFinder record setting to REG (1-8) makes for quick set up of custom song regs, supporting whatever custom settings you desire (transpose, split point, voice selections, etc). All and all, I remain very satisifed with my Tyros 4 and appreciate the many improvements (both sound & features) over Tyros 2 and 3. 
Yamaha needs to listen more to their customers needs ....or take a page out of KORG's songbook feature, Dual Mp3 player and Liontrac's larger display size, Ketrons ability to play independent simultaneous Play MODES with sliders. Ahhhhhh whats the use.
