For me the most essential feature requests are:
EQ per track - must have! I do not understand this was implemented at first.
This to get a better mix of the 8 tracks!! Most wanted on the RYTM as well.
Internal Midi control, so you can control the fx with parameter locks and the use of extra LFO's
Sample editor/page with zoom
Ctrl-all filter. So you can choose which tracks are affected.
Per track you have a setting: Ctrl-all : on/off
So you can parameter lock this setting as well.
