or feel, and therefore,
is
consistent with the rest of the
performance. In this case, enter record ready by
pressing the record and play buttons simultaneously.
The record mode will be activated when a FUNCTION
SELECT button is depressed.
When the FUNCTION SELECT
is
in the UP position,
the musician
will be monitoring reproduce (sync) and
probably play along with the previous performance
until the
time comes to punch-in the correction. When
that moment occurs, simply press the appropriate
FUNCTION SELECT button for the corresponding
track that is ready to be recorded. Two things then
happen. First, you instantly enter the record mode on
that track, and the new part
will replace the previous
one, in sync of course. Second, the monitor
is
automatically switched from tape (UP position)
-
sync
reproduce
-
to source (DOWN position)
-
so the
musician
can hear his new part as
it
is being added. The
logic remains consistent.
3. For very brief "punch-in,"
if you can "cue" or find the
spot to begin re-recording by listening to other tracks
-
depress FUNCTION SELECT to the READY posi-
tion, put the transport in PLAY. For short segments
you
can now press RECORD and hold it down. The
recorder will stay in the RECORD mode as long as you
hold down the RECORD button. When you release it,
the tape will play, but will not be erased. This mode
will
allow you to re-record small parts of a track that
are separated by sections you wish to keep quickly, but
since you cannot hear what's on the tape,
it
can be
risky. You
can also enter and leave the record mode by
raising and lowering the function select buttons while
the transport is "locked" in the RECORD mode. It's
not necessary to enter STOP to stop recording. This is
called "punch and roll" and is sometimes very useful.
Again
it
is
risky because you run the risk of waiting too
long to "punch out." Be careful.
