is this normal this graphic on the waverform if you overdub more than 2 overlay?
You can see like a volume boost on track 2 , but only on the begin
This is a common graphical error, it happens sometimes, but is not reflecting the volume it is only a visual glitch.
We may fix this once we get to more polishing which may come sooner than later, I will tag it as #under-investigation
Thanks for reporting
