Unfortunately my midi regions do not respond to the “Transparent” or “Opaque” setting. No matter how I set it, they always remain transparent (even if “Opaque” is checked).
(The audio regions respond to these settings)
Your tip to set the recording mode to “Draw” would theoretically work, but I don’t want to lose the old regions.
I just want to ensure that only the upper region is played.
My pragmatic but not smart solution would be to mute the entire midi track until I’m happy with my recordings. Then I have to cut the layers so that they don’t overlap. That doesn’t sound like fun.
