I can't think of any steps I missed to keep the volume balance set in Split Mode, but when saving the patch the volume balance is not saved. This is how I do:
1. PRESET and DEC/BANK SELECT to SPL
2. PRESET and B appaear
3. VELOCITY hold, decrease the volume of split B with DEC/BANK to lets say 70
4. PRESET and A appear
Now the balance of the volume is adjusted and works as expected
5. REC and the Patch to the original of A, lets say 211
Now the volume balance is lost and back to before edited
What am I missing?
