themselves are not moving, but the audio levels are changing nonethe-
less. The faders are simply resting in the last position that you left them at.
So most of the time during playback, the physical position of a fader will
have no relationship to the actual level of the VCA, which will continually
vary just as you have programmed.
For example, MixMate may turn the audio level to full attenuation (i.e. all
the way down), but the fader has been left "full on" from a previous pass.
Suppose that you were to ENABLE the fader now to do a re-write of the
channel. As soon as you moved the fader the gain of the VCA would jump
up to meet the fader. NULL LEDs have been provided to avoid this situa-
tion. The NULL LED is lit when the physical position of the fader corre-
sponds to the actual level of the VCA. Slide the fader down or up just until
the NULL LED comes on. You can now ENABLE the fader to re-write the
channel moves without any jump in level.
In WRITE MODE you may selectively rewrite (that is, replace) any fader
moves in any part of the song. Simply fast wind the tape to a point a few
seconds before the offending fader moves.Start the tape, then use the
NULL LEDs to help you find what the actual VCA level is at that point in
the song. Slide the fader down or up just until the NULL LED comes on.
Now the position of the fader accurately reflects the level of the VCA. Then
ENABLE the fader(s) that you wish to rewrite, and enter the new moves.
The faders may be ENABLED before the tape is rolling if you prefer.
As mentioned earlier, UPDATE MODE is useful for rescaling (or "off-
setting") fader moves without actually replacing them. Any moves made
in UPDATE MODE will be "added to" or "subtracted from" previous
moves. To UPDATE a track, once again shuttle tape to some place in the
song before the intended edit. Put
MixMate into UPDATE MODE by tap-
ping the MODE key until only the UPDATE LED is lit. Don't null the fad-
ers just yet. Decide what the nature of the update will be, whether you
intend to scale the track up or down. If you plan on boosting the level, you'll
want to start with the fader below center position. This will assure that you
have enough "throw" to move the fader upward. Likewise, if you plan on
scaling the track down, you'll want to start with the fader above center.
If you are not really sure, then just move the faders to approximately
center position . For the channels that you wish to update, use the ENA-
BLE keys to toggle from READ into UPDATE MODE. (Be sure that you
are not in MUTE MODE for now.)
Start tape (or other source of sync). The starting position of the fader is
