Could be useful in the case like in the video below for example.
What I m trying to do is :
After recording and when the sequencer is running, play override on a multislice to modify its end point and its envelope before applying the change with A+pad.
So for a visual feedback I have to switch back and forth multislice waveform editor and multi envelope.
Multi envelope no problem the B button stays lit and it goes directly to the envelope editor.
Multislice wave editor is not very handy because the window is closed and zoom settings are lost so each time I switch back and forth I have to press B and zoom in again.
