voltages or expression pedals corresponding to the five controls: Freq,
Wave, Env. Amount, FM Amount, and Mix. All of these inputs accept an
expression pedal like the Moog EP1 or EP2 with tip-ring-sleeve plugs, or
a CV on standard tip-sleeve cables. All inputs are added to the setting of
the front panel controls. With expression pedals plugged in, set the panel
control to the lowest setting you want with the pedal in heel position,
then when you advance the pedal, it increases that parameter, just as if
you were turning the control on the front panel clockwise. The following
are the details of each input’s behavior with control voltages:
- Freq CV In accepts a -5 to +5 CV signal, and is calibrated for the VCO
to change one octave for very volt change at the input. The control input
extends the frequency range of the VCO well beyond the 25Hz-1.6KHz
range of the front panel Frequency control. The VCO oscillates from sub-
audio up to 20KHz.
- Wave CV In accepts a zero to +5V CV signal. The range of effect from
a zero to +5V CV is 60% of the range of the front panel control.
- Env. Amount CV In accepts a zero to +5V CV signal. The range of
effect from a zero to +5V CV is 100% of the range of the front panel
control.
- FM Amount CV In accepts a zero to +5V CV signal. The range of
effect from a zero to +5V CV is 100% of the range of the front panel
control.
- Mix CV In accepts a zero to +5V CV signal. The range of effect from a
zero to +5V CV is 100% of the range of the front panel control.
CV Outputs: The FreqBox has two CV outputs which can be used to
modulate other Voltage controlled gear, such as Moogerfooger analog
effects, the Minimoog Voyager analog synthesizer or Little Phatty analog
synthesizer. The following are the details of these outputs:
- Env. Follower CV Out: This is the unfiltered Envelope Follower CV,
which is generated from the Drive signal. The Envelope Follower CV
is only produced when the effect is active and a signal is present at the
audio input. The level is nominally zero to +5V. This signal carries larger
audio-induced ripple than the signal used for modulating the VCO, or the
VCO’s VCA.
- Oscillator Direct CV Out: This is the direct output of the VCO’s
waveshaping circuit before it goes to the VCA, so this signal is
always present, and is nominally +/-2.5V. That’s a lot stronger than an
instrument level signal, so we don’t recommend plugging this output into
an instrument amplifier.
