Wonder why the SX 900 won’t hold edited changes to a “Quick” midi recording, when changes are made to the tempo, volume levels, and panning? Done that a zillion times on the S975 with no problems. On the SX 900, when you go to resave the song after editing, the prompt reads that to do so will overwrite what’s there. I say “Yes” which is what I want to do. Then, on playback, the song reverts back to all settings in the original recording. Checked Chapter 5 in the reference manual, which only covers multichannel recording and step recording, not the quick recording. I can’t believe the SX 900 can’t do what previous PSR models could do.
