In a multiple ADAT system which combines one or more XT20s and one
or more original ADATs, you can use the XT20's Track Copy function as a
way to reroute its digital output to different tracks on the ADATs.
Let's say you have one XT20 which is the master, and one ADAT which
is the slave. When you normally record the digital output of the XT20
to the ADAT, the tracks are transferred on a one-to-one basis. In other
words, track 1 of the XT20 is recorded onto track 1 (9) of the ADAT,
track 2 goes to track 2 (10), and so on. By using the Track Copy function
on the XT20, any track on the XT20 can be sent on a different channel.
For example, you could have track 1 transmitted as channel 8, which
means you can record it onto track 8 (16) of the ADAT.
In the following steps , we will illustrate how to accomplish the above
example:
On the XT20, press and hold [TRACK COPY].
Press RECORD ENABLE [1] to select track #1 as the source
track.
Release the [TRACK COPY] button.
Press RECORD ENABLE [8] to record enable track #8 on the
XT20.
Press [DIGITAL IN] on the ADAT and press RECORD ENABLE
[8] to record enable track #8 (16) on the ADAT.
Press [PLAY] on the XT20.
Press [PLAY] and [RECORD] on the slave ADAT.

The Alesis BRC provides a way of setting tape offsets using any of the
20 Locate memories in a song. This means you can set a Locate at one
point, another Locate at another position, then have one of the slave
ADATs offset by the amount of time between those two Locate
positions.
The XT20 allows you to set a Tape Offset by entering a time reference.
For example, if you were to set a Tape Offset of 5 minutes (0:05:00.00)
and the rest of the ADATs were at 0:03:23.15, the XT20 would be at
0:08:23.15.
But let's say you don't know the time difference (i.e. the offset amount)
between two sections of music. For example, let's say you wanted to
bounce the vocals from the chorus 1 section of a song on an XT20 to a
slave ADAT, then bounce them back to the XT20 while it was offset to
the second chorus. To do this, the XT20 needs the exact offset time
between these two positions in the song. So how many minutes, seconds
and hundredths-of-a-second away is chorus 2 from chorus 1? Here's a
way to find out by using the Locate Points.
Play the tape(s) back from just before chorus #1.
Press and hold [SET LOCATE].
When you get to the downbeat of chorus #1, press [LOCATE 0].
