Waveform
The Waveform selector determines the wave
shape used by the LFO. The waveform shape in
use is graphically depicted by the movement of
the Sound Location indicator in the Panning
display.
LFO Triggers
By default, the LFO cycles continuously through
the selected waveform. The LFO can be set to cy-
cle through the selected waveform just once, or
it can be triggered by MIDI Beat Clock, the En-
velope, or manually.
Single
When the Single trigger is selected, the LFO will
cycle thru the waveform once only and then
stop.
Beat Clock
When the Beat Clock trigger is selected, the LFO
synchronizes to MIDI Beat Clock. TL AutoPan
receives Beat Clock signal every 64th-note. The
Duration menu determines how often the Beat
Clock signal triggers TL AutoPan, ranging from
every 16th-note to every 4 bars. When Beat
Clock signal is received, the Beat Clock trigger
light blinks brightly. Using the Beat Clock func-
tion enables TL AutoPan to produce consistent
panning results, ensuring that the LFO is always
in the same state at each beat.
Envelope
When the Envelope trigger is selected, the LFO
is triggered directly by the Envelope Detector,
which analyzes the amplitude of the audio sig-
nal. If the Side-Chain Input selector in the Enve-
lope section is activated, then the side-chain au-
dio signal is used instead. When activated, the
Envelope light blinks brighter when an audio
signal is detected. The threshold level can be ad-
justed using the Threshold control in the Enve-
lope section.
If the Envelope Detector is completely released
due to previous portions of the audio signal go-
ing above threshold, a trigger occurs the next
time the audio goes above the threshold level.
Another trigger will not happen until the Enve-
lope Detector has completely released after the
audio goes below the specified threshold. In-
creasing the release time reduces the rate at
which triggers can occur and decreasing the re-
lease time increases the rate at which triggers
can occur.
