Detailed Operational Information
Using Auto-Dub Feature to Transfer Material From VTR to Disk
The vtr Auto-Dub feature is not supported in firmware version 1.1 for the TDC-100B
The Record Trim menu item is still in place, but has no function at this time.
Using Multipoint Loops
The TDC-100B has the capability to do multi-point loops, where for example you play
a lead-in, loop an internal portion, then (upon receipt of a ‘exit loop’ trigger) play a tail
out. Doing this requires four time values.
Start Point --- Loop In --- Loop Out --- End Point
The way the controller accomplishes this is to use a pair of registers. The first
register must be in the range 000-099. This register contains the Start Point, and the
End Point (the two ‘outside’ times). The second register is in the range 100-199. It
contains the Loop In and Loop Out times (the two ‘inside’ times). You select the
lower register to run the loop. The controller will always look at that 100
for the two inside times, i.e., if the lower register is 025, the controller will look at
register 125 for the two inside times.
The inside loop must have a minimum duration of 1:15, just like a normal loop, and
must have both an inpoint and an outpoint. The Start Point must be at least as early
as the Loop In point. There are no requirements placed on the End Point. There
need not be a time in that register. If you do want to play a tail out (4-point loop) the
End Point must be later than the Loop Out.
Once the Start and Loop times are entered, you can start the Multi-point loop (or
MLoop, as it’s displayed on the TDC) by sending a Pbus Trigger 8, or by pressing
<FCN>, then <8> on the keypad. This will cue the disk to the Start Point, if it isn’t
there already, and begin playing. When the disk gets to the Loop Out point, it will
jump back to the Loop In point (the inner loop). It will continue to run this loop until
you do any one of the following:
Stop the loop with a STOP trigger or button press
Recue the loop with a RECUE trigger or button press
Recall another register (with PRESERVE LOOP turned off)
Send a MULTI-LOOP EXIT Pbus Trigger (trigger 9), or press <FCN>, then <9>.
If you send a MULTI-LOOP EXIT trigger, or press <FCN, then <9>, the disk will exit
the loop at the first opportunity, and play until it reaches the End Point. If there is no
End Point defined, it will play until stopped. Also, a GPI output will be triggered at
