Another thing i would love to see is an option for the mfc controll (pedal) changes, to function as the main volume pedal on Genos.. there is much more depth in these settings, and they can be assigned to a performance memmory..
You can control the right voices with the MFC10 expression pedal:
https://www.psrtutorial.com/forum/index.php/topic,40058.msg323332.html#msg323332Instruction from a PSR Tutorial member lacobo:
"To Program the Foot pedal: (the volume pedal on the right side of the MFC-10)
1 Hit button 1 of the MFC10 in F-mode (F01 appears in the display)
2 Press the FC Edit button
3 Set the Status to bF (+ FC Edit button)
4 Set DataContrl to 007 (+ FC Edit button)
5 Set Max to 127 (+ FC Edit button)
6 Set Min to 0 or higher (+ FC Edit button)
7 Press the Write/Exit button
8 Press the Inc/Yes button to save the setting
9 Set in the Genos the receiving midi-channel A16 to Keyboard <-- On Genos, the default midi channel for this is already A16.
And voilla, you can alter the volume of the voices you play."
