Regarding Lee's question of whether the newer voices are used from older regs,I have so many from the PSR S970 I want to use,but don't want to miss out on the new sounds. I know many of the styles are the same,but would I be getting the reworked effects by importing the 970 reg? A different question is always whether the SX has a better style,but I guess auditioning is the only way to answer that.
