Better vibrato editing

I couple ideas for better vibrato editing:

  • Allow for editing of vibrato even in Instant Mode
    (Currently, Instant Mode seems to add vibrato by editing the pitch deviation of the notes. Editing would be easier if Instant Mode edited the vibrato parameter instead. Then, for example, we could set a high pitch expressiveness in Instant, but still control the start time and depth of vibrato).

  • Vibrato speed envelope
    Currently “Vibrato envelope” only controls depth. It would be great to be able to control the vibrato speed over time.
