Rehearse; Track Delay Time - Alesis BRC Reference Manual

The display shows the current crossfade time as follows:
Crossfade Time
There are four possible crossfade times: 10.67 ms, 21.33 ms, 32 ms and
42.67 ms. These time values assume a playback rate of 48KHz, and are
therefore not exact if the pitch is changed, or an external clock source
is used.
2. Use the UP/DOWN buttons to cycle through the different
crossfade times. The change takes place immediately.

3.5 REHEARSE

This button is used to enable and disable Rehearse mode. When
pressed, the REHEARSE LED will light to indicate that the you are in
rehearse mode (i.e. any "recording" will not actually be saved to tape).
For example, when punching in and out with Auto-Punch turned
on, the record-enabled tracks will switch from tape monitor to input
monitor and back to tape monitor, thus allowing the user to rehearse
the new material.
• When in Rehearse mode, nothing is saved to tape and therefore
nothing is lost. Both the BRC and individual ADATs will flash
their RECORD LED to indicate that recording is not taking place.
When the REHEARSE button is pressed again, the LED will turn off
to indicate that you are no longer in Rehearse mode and all further
recording will be saved to tape.

3.6 TRACK DELAY TIME

Track Delay lets you shift tracks up to 170 ms back in time, in order to
achieve a more desirable "feel." For example, if the bass track is
anticipating the beat, you can push it back in the pocket by delaying it
a few milliseconds. If you need one track to play back earlier than the
others, try offsetting all other tracks by the same amount. This will
make the remaining track seem to play ahead of the others. Track
delay can also be useful for creating effects. For example, you could
record a snare track onto another track with delay on. When playing
back the two tracks together, the result is a flammed snare.
The TRACK DELAY button is used to toggle the delay time on and off
for selected tracks. When this button is pressed (LED lit), any stored
track delays are in effect. When this button is pressed again (LED off),
