 The Classic VCO
is the highest quality analog oscillator module ever made. It produces the standard classic analog waveshapes -- sine, triangle, sawtooth and pulse with pulse width modulation. It also
has a unique random voltage output which provides 64 random voltage levels. In the audio range, this sounds like "noise" of various
colors depending on the tuning of the oscillator. In the "low" range, it can be used in the same way as a noise generator feeding a sample and hold.
The Classic VCO has three exponential control inputs, one with attenuator. It also has an AC coupled linear input with attenuator and a propotional sychronization control with attenuator. In addition, this
module contains a simple attack-release envelope generator (which can also be used as an envelope follower or lag processor) and a voltage controlled amplifier (VCA) with two mixing inputs. The VCA is intended to be
used with the "Velocity" output of a MIDI to CV convertor but can be used as a general purpose VCA. The modulated pulse output is normalized to one VCA input while the
output of the envelope generator is normalized to the VCA control input.
Red and Green Bicolor LEDs monitor three of the waveform outputs and the voltage output of the envelope generator is displayed by the brightness of a fourth LED. The
output level of the VCA is displayed on a four LED VU meter.
The Classic VCO module contains:
- A five waveform pure analog oscillator
- An Attack-Release Envelope Generator. The envelope is set by an internal jumper for either exponential or linear envelopes.
- A Voltage Controlled Amplifier (VCA)
- A jack multiple
The
Classic VCO is available for US$CALL, and can be ordered on our
