At the moment, if I have two notes:
C-5
...
F#5
the MIDI messages sent to VSTis place the Note Off for the C-5 just just before the Note On for the F#5, which is fine. However, it'd be good to have a 'legato' mode -- essentially, the C-5 Note Off is sent a tick or two after the F#5 Note On.
I can do this manually by swapping constantly between two channels, but it'd be really good if this was a configurable instrument parameter. Basically, it would let you do slightly more interesting things with legato, especially on plugs that don't have legato functionality built-in.
