Optimizing Level Triggered Playback
These tips will enable you to obtain tight level triggering
for percussion replacement and other critical applica-
tions.
14. Make sure there is no "dead air" at the head of your
sample. The non-percussion samplers are preset to
MARK and preserve a few milliseconds of pre-trigger
audio for the FAST FADE UP. You may either MARK
THE HEAD (0 milliseonds) or trim this later.
15. Marking the HEAD while using the preset -24dB
level-triggered recording should provide a tight enough
HEAD trim for most users. You may tighten the record-
ing further by setting MODE to a higher dB level.
16. Besure to set FADE TYPE to PERCUSSION for
sounds with tight, clean attacks. If the cue is still too
loose, then trim HEAD until just before you hear loss of
the attack.
17. Adjust TLV, playback trigger level, for the greatest
sensitivity that doesn't give false triggers.
Note: If you are using level retriggering to interrupt
and restart sample playback, a combination of too
sensitive a trigger level and insufficient retrigger
holdoff time can lead to a stuttering, which some
hear as a great effect. If it's not for you, remember
these general guidelines.
• Use a short duration retrigger signal with a sharp
attack.
• Raise the level threshold - if this can be done
without delaying the initial trigger.
• Make the HOLDOFF time as long as possible
The Bank 7 Dual Rate Change sampler has a fixed
retrigger HOLDOFF of about 100 milliseconds. The
forward/reverse sampler cannot perform level retrig-
gering, it can only be retriggered manually or via MIDI.
Bank 7: the Sampler Programs
Using Rate Change Samplers
1. Both SME samplers and the Bank 7 sampler, Dual
Rate Change, permit you to adjust the playback RATE.
Starting with Version 3.00 software, the display now
shows percent of normal speed and, over a certain
range, musical interval from unison. The pitch interval
display corresponds to that of the pitch changer, Bank
8, programs 1 through 6, and shows the range over
which you may correct the sampler's pitch. You can
cascade these programs for simple time compression.
2. The non-SME Dual Rate Change sampler allows
you to record, edit and playback two independent
samples. Use the VX, RECORD VOICE slider to select
a voice for the Page 1 Record controls. Record and
check a sample as above.
3. There are two independent editing pages, and
independent play controls for each voice. Voice 1
comes out the left side, Voice 2 out the right.
Using the non-SME FORWARD/REVERSE
Samplers
1. The sampler is preset to play only the forward
voice. To activate the reverse voice, adjust REV TIME
(slider 5) to some large number, and adjust TAIL TRIM
to tighten the beginning of the backwards play.
2. To turn off either voice, move its TIME slider to
0.000 SEC.
3. To adjust the relative start times of two active
voices, use the "<>" slider, PLAY ORDER. For a
different kind of inverse effect, try sliding the forward
voice so that it starts just as the reverse is finishing.
4. Adjust the relative gains and panning of each
voice on Page 3.
