The HD24 can scrub all tracks of audio for a given song. When stopped, the user can press and hold the Stop button, followed by the FastFwd or Rewind keys to scrub any or all tracks. (Other remote scrubbing from wheels on a MIDI controller or the M20/CADI, is not supported.) Or, you can trim a point numerically in the display, second by second, frame by frame, until it sounds right.
