Lexicon 480L Owner's Manual
Time Variant Recording
The original (and still available) IMMEDIATE record
mode allows control over the start time only. Recording
starts when the REC button is pressed, and continues
until all audio memory is used. We now use the term
capturing to describe a sampler that records until a
triggering event stops it. Time Variant Recording pro-
vides controls that determine exactly what audio is
captured (the MARK slider) and how it is captured (the
MOD slider, REC key, and CAP key).
The recording side of the sampler has three states:
READY, RECORDING, and CAPTURING. In the
READY state, all recording is complete, and the 480L
is ready for playback or to record again. Tap REC to
begin recording.
To determine which of the three states the sampler is
currently in, tap CHK or CUE. If the sampler is READY,
the LARC displays the name of the key and plays the
sample. If the sampler is recording, but not yet trig-
gered, the LARC displays:
RECORDING
************
The asterisks indicate that the sampler is armed and
ready to record. If the sampler has been triggered
manually (by pressing CAP), by level, or IMMEDIATE,
the LARC displays CAPTURING and the asterisks
disappear one by one until completion. Pressing CHK
or CUE will not disturb recording.
MARK may be adjusted from the HEAD of the sample
to the TAIL. If MARK is 0, everything after the trigger is
saved. If MARK is TAIL, everything before the trigger is
saved.
The most obvious application for the Capture mode is
level triggered capture, with MARK time set for zero or
just above zero. The response is extremely fast, so the
capture will really nail a percussive sound. Set FADE
TYPE to PERCUSSION, and set the Trigger Level as
low as possible.
Some useful applications are described below:
1. To obtain the original, simple form of recording.
MOD = IMMEDIATE
6-6
2. Percussion capturing. Triggers on first audio,
trimmed exactly. Everything after the trigger is saved.
MOD = Appropriate dB level
MARK = HEAD
3. Stop when finished. Triggered by user when
sound is ended. Everything prior to the trigger is saved.
MOD = USE CAP KEY
MARK = TAIL
4. Reaction time manual capturing. User taps REC
to arm the 480L, waits for sound to start, and then taps
CAP. Sound for the period of time set with MARK prior
to tapping CAP is saved.
MOD = USE CAP KEY
MARK = An appropriate period of time
5. Level triggered capturing. Same as reaction time
manual capturing, but level triggered instead. Useful
for sounds that build more slowly than percussion.
MOD = An appropriate level
MARK = An appropriate time
Sampling Percussion
When sampling percussion, set FADE TYPE to PER-
CUSSION. The sample will start with a hard cut instead
of the normal FAST FADE. If the sample plays com-
pletely, the end is always faded down. From Version
3.00 on, the SME and the overdubbing non-SME
samplers have been modified so that a PERCUSSION
mode retrigger will cut rather than fade out the running
sample. This improves synchronization in fast percus-
sion replacement applications. (It may also result in a
click in non-percussive samples, so be careful in
choosing which type of fade you want.)
Scrubbing
A feature of the SME samplers is their ability to continu-
ously vary the speed of playback within the limits
described in the earlier program descriptions. There
are four speed regions defined by these end points:
-200%, -100%, 0%, +100% and +199%. You can vary
the RATE at will within these regions, but crossing the
boundaries may cause glitches whose audibility de-
pends on the source material.
