Scrub function
When editing a sound, some times you need to know exactly
where the sound starts, or exactly where the recording with
an auto punch in starts.
To enable you to find these points accurately, the BR-900CD
is equipped with the Scrub function.
When you use the Scrub function during playback (called
“scrubbing”), the portion from your before or after the
current location (approximately 45 msec) is played back and
repeated.
Preview function
With the Preview function, you can playback the one-second
portion of the song before or after your current position.
By using this together with the Scrub function, at the same
time slowly moving your current position in the song, it
becomes easy to find the exact transition point from one
phrase to the next.
