Rate/Time
Knob 4
This value sets the pitch slide rate or slide time. The setting determines the slide rate (if
the mode is set to "rate") or the slide time (if the mode is set to "time").
Slides one note into the next only if the first note (key) is still
held when the next note is struck. The slide time is always the
same; the slide rate increases as the difference between the pitches
increases.
Pitch between consecutive notes always slides, even if the first
note is released before the second note is struck. Again, the
slide time is always the same.
