152 Automix
02R User's Guide
ABSOLUTE—In Absolute mode, real-time fader edits are recorded as is
(i.e., the new fader movements overwrite the existing events).
RET (Return)—With the RET option on, the fader returns to the position
previously recorded at the point recording stops. You can specify the
return time from 0.0 to 3.0 seconds. The RET option works when automix
recording is stopped using the STOP icon, the incoming timecode is
stopped, or the channel is dropped out of recording using a [SEL] button.
END (Write to End)—With the END option on, the fader (CH ON, PAN,
EQ, SURROUND, aux send level, or MIDI Remote) remains at the
position where recording stops, and remains there all the way to the end
of the automix (i.e., data up to the end of the automix is rewritten to
accommodate the new fader position). The END option works only when
automix recording is stopped using the STOP icon, or the incoming
timecode is stopped. It has no effect if a channel is dropped out of
recording using a [SEL] button.
With both the END and RET options on, the fader returns to the position
previously recorded at the point recording stops and remains at that
position all the way to the end of the automix data (i.e., data up to the end
of the automix is rewritten to accommodate the fader position returned to
when recording is stopped).
Using the END option in Relative mode allows you to apply a relative
level change to all fader events for a channel through to the end of the
automix. Instead of having to record a relative level change all the way
through to the end of the automix, END allows you to stop recording
soon after making the level change, and have the 02R automatically
rewrite the data up to the end of the automix to accommodate the new
fader position.
If the END, RET, and RELATIVE options are all on, when recording is
stopped, fader data up to the end of the automix is not rewritten.
Fader Edit
When you record a fader overdub, this display shows the previously
recorded level and the new fader setting, plus an arrow indicating which
direction the fader will have to be moved to return to the previous level.
Refer to the following diagram:

than the previously recorded position
