The BRC's
•
SAVE SETUP TO TAPE
commands (which saves the BRC's
FROM TAPE
internal data and song setups to the DATA
section at the head of an ADAT tape) are not
supported by the HD24. So, if an HD24 is first
in the Sync chain following the BRC, then the
BRC's song data cannot be saved or restored.
No "search" command:
•
ADAT, pressing both
will put the ADAT into "Search" mode. This
mode is not supported by the HD24.
HD24 will wait until the tape ADAT has
completed its search and locate to the new
timecode once the Locate command is sent.
No pre or post roll outside Song
•
boundaries:
Post-Roll are only supported if you have
sufficient time in the song. That is, the pre-roll
value cannot access points before sample 0, and
the post-roll value cannot go past the last
sample of the song.
If you require Pre-Roll and Post-Roll, create a new
Song in the HD24 that contains the required
additional time, and copy/paste the old song in the
middle of the new song.
Other issues
No punching in on track buttons:
•
In a tape/HD system controlled by a BRC, if
tracks are armed on the tape but not on the
HD24, punching in on the BRC will put the
HD24 in Record Pending mode (Record LED
flashing). Once in Record Pend, the HD24
cannot dynamically arm tracks, nor can it
extend the song length. You must arm tracks
before entering RECORD on the BRC.
High sampling rates:
•
control an HD24 if the current Song is at the
88.2 or 96 kHz sampling rate. The BRC is
designed for 48 kHz operation primarily
(although you can use the BRC's PITCH
controls to reach a 44.1 kHz sampling rate).
Songs are separate:
•
command cannot select different Songs
SONG
on the HD24's hard drive. (For one thing, the
BRC has only 20 songs in memory, while the
HD24 may have up to 64.) Nor can the BRC

Location points separate: While both

location points and names are in the BRC's

The only exception is that, once you perform
a punch-in from the BRC, the punch-in and
out locations (L21 and L22) of both the BRC
and the HD24 will be updated to the same
values.

The
Auto Return display:
•
mode on the BRC will not engage the HD24's
Auto Return feature, only Auto Play.
However, this is only a display issue, as the
BRC handles the looping functionality.
Track Delay, not advance:
•
BRC's
HD24's track delay feature, but only in one
direction: it can delay a track up to 170 ms.,
but can't advance them (since tape-based
ADATs were not capable of that).
