Hi Cluso,
No there's not such shortcut.
The more difficult part for that kind of feature is the UI part.
What key to use ? to copy ? to past ?
Any info on the screen showing an operator is currently copied in the buffer ?
Also midi out must be sent for the 11 parameters that are modiffied.
I have to think a little about that.
But that would be usefull i agree.
Specially if it works per page : oscillator, enveloppe, LFO, Matrix.
