John, got your point, good one!
The note off for the "legato" notes is sent only upon stopping Octopus – and basically leaving all the work in between to the synth, if you want.
Will look into a way to make it work the way you suggested. Right now this feels like a bit of work, but it would help if you Could rate this from a priority perspective (from 1 to 3). That will help us channel it better.
