One guess I知 thinking is depending on major or minor chord the muted channels are still playing in the background. When I play the same style (style itself) on the genos 2 the Brass sounded full blown all the way. Most of the time. This is interesting to me how well voices sound痴 during style playback and song(midi) playback. Another guess is I知 thinking maybe the way the firmware is programmed the style voices will sound its best when recorded/played back as a song/midi file. I知 still curious is the style file using more note polyphony or is it software related.
