Sorry to interupt. I am new to BIAB and maily use it to get and practice music on clarinet.
I have been looking at the piano roll window and can understand the one for notes. Can anyone explain in simple terms what the lower panel does.
e.g what does the height of an event signify?
What is velocity?
How do you change pitch, duration, velocity etc.
Does the lower panel reflect what is done in the upper panel.
Finally I get the impression that the lower panel is for MIDI control. Is this correct?

If this is not the right part of the forum to get answers to this can you please direct me gently to the correct section of the forum.]Thanks in advance.
