Key Features
The Cwejman VM-1 Voice Module is a voice module providing multiple features including a built-in oscillator, multi-mode filter, amplifier and two different envelope generators. The VM-1 is capable of producing strong, clean sounds. The VM-1's oscillator can produce 7 waveforms with attenuators for controlling pitch. Its 4 pole multi-mode filter consists of an audio mixer, filter cutoff, resonance control and output morph. Low pass, high pass and band pass are available and allow you to mix between with them with the MODE MORPH attenuator.

The Cwejman VM-1 features an oscillator that is a powerful and versatile tool. It offers 7 waveforms for you to choose from including sine, triangle, saw, saw and triangle, pulse and triangle, saw and pulse, and variable-width pulse. The VM-1 provides enough waveforms to create a vast array of sounds. Pulse width modulation is available for the pulse wave and the other waves that include pulse. The main oscillator provides 4 control inputs with CV1 and CV2 calibrated to 1V/oct ensuring they track accurately over a large number of octaves. Pulse width modulation is available with the use of a knob that attenuates the CV through the PWM input. The VM-1 features a sync input that can control the oscillator through an external device.
Alongside the oscillator is the multi-mode filter with multiple controllable parameters. Whilst still providing the low pass, high pass and band pass modes, the 4 pole multi-mode filter allows you to morph between the different modes and includes a CV input allowing you to use a control voltage to determine its action between low pass and high pass. When the Q-peak (resonance) is set to maximum the filter self-oscillates. Featured at the bottom of the multi-mode filter section is an attenuator labelled CM1 and a switch for choosing OSC or AR. This determines whether the internal CM1 control voltage comes from the AR contour generator or from the oscillators output which makes all audio FM effects possible. The EXT-CM input is for adding an external signal into CM1. Turning the CM1 knob allows you to adjust the source and depth of the modulation from either the internal signal (anti-clockwise) or the external signal (clockwise).
