Jim, you are correct,but Roland handles polyphony a whole lot better than Yamaha,Korg and Ketron..and that is a proving fact....For example, the PSR9000 [128] couldn't compete with the G1000[64],,how to play without dropouts, and in some examples with older PSR's, shut off[no sound when polyphony is used up]...When it comes to voice allocation Roland knows what they are doing...Numbers don't tell the real story...playing does...
