Modules 4

• A-110-1 Standard VCO 10 HP

  Voltage-controlled oscillator producing four waveforms simultaneously (square, sawtooth, triangle, sine) with a frequency range of about ten octaves, controlled by Range switch, Tune knob, and CV inputs.

• A-118 Noise / Random 8 HP

  A noise and random voltage generator producing white noise, colored noise, and random voltage.

• A-120 8 HP

  Voltage controlled 24dB/octave transistor ladder lowpass filter with three CV inputs, manual cutoff frequency control, and resonance adjustable to self-oscillation.

• A-124 8 HP

  Special voltage-controlled multimode filter with a cut-off slope of -12dB/octave, using the peculiar electronic circuitry of the EDP Wasp synthesizer. Abuses digital inverters as analog operational amplifiers. Has band-pass output and combined low/notch/high-pass output. Cannot self-oscillate.
