Would be a nice feature, just like Octamed 1.3+ has it, too. For example you use a vst bass, and wanna it note-off slightly before the next 16th note appears, per default. Now you could of course place various note-offs and trimming then with delay values… Much more simple in this case would be sustain value in the instrument midi options, in ticks…
If there a note-off is approaching, the sustain value could be ignored. That would require some note pre-looking.
Thanks.
