FRONT PANEL CONTROLS
RATE (Large Dial)
- This ad-
justs the rate of the triangle
and square LFO.
RATE LED
- Indicates the
rate of the triangle/square
LFO.
RATE (Trimmer)
- This ad-
justs the RATE CV amount.
When no plug is inserted into
the RATE jack, this controls
the amount that the FSR
will control the rate of the
LFO. With a plug inserted,
this controls how much the
external CV affects the LFO
rate.
TRI/S&H/SQR
- This switch
selects the output wave-
AMP (Large Dial)
- This ad-
justs the output amplitude of
the LFO signal at the OUT jack.
AMP LED
- Indicates the am-
plitude of the LFO OUT signal.
AMP (Trimmer)
- This adjusts
the AMP CV amount. When no
plug is inserted into the AMP
jack, this controls the amount
that the FSR will control the
amplitude of the LFO. With
a plug inserted, this controls
how much the external CV
affects the LFO amplitude.
S&H
- This is the output of
the internal sample & hold
circuit. The S&H signal can
be accessed here, even when
other output waveforms are
form of the HLFO. In the center position,
the Sample & Hold output will be routed
through the LFO VCA and inverted.
NOISE
- This output provides a noise
source. The noise output is +5V to -5V.
SRC
- Sample & Hold source input. The
internal sample and hold circuit is nor-
mally sampling the internal noise source
when nothing in plugged into the SRC
jack. Plugging into SRC will disconnect
the noise, and the external signal will be
used as the sample source.
selected at LFO OUT.
FSR
- FSR Output. Pressing on the FSR
will generate a voltage from 0 to 5V,
based on how much force is being used
on the sensor pad.
CLK
- Sample & hold clock. Use this input
to clock the S&H circuit. Incoming clocks
should be a square wave with an ampli-
tude of at least 3Vpp.
