Model 341 Classic VCO

Envelator

Introduction

The Classic VCO produces the standard classic analog waveshapes: sine, triangle, sawtooth, and pulse with pulse width modulation. It also has a "random" 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 can be used with the "Velocity" output of a MIDI to CV convertor, or 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.

Features:

• A five waveform pure analogue oscillator
• An Attack-Release Envelope Generator
• A Voltage Controlled Amplifier (VCA)
• A jack multiple
Bantam (TT) or 3.5mm jacks
