VCO 2100: Voltage Controlled Oscillator 

• Highly Stable One Volt per Octave Response 

(Meets or exceeds industry standards for stability and tracking accuracy)
• +/- One Octave Input for Transposing
• Linear and Exponential FM with Switch and Level Knob
• Voltage Controlled Waveform: Triangle to Square with "Tube" Sound
• Voltage Controlled Pulse Width Modulation
• Five Output Waveforms: Sine, Triangle, Sawtooth, Pulse and VC Wave
• Sync Input
• Standard +/-5V Waveform Levels
• Built in precision voltage reference for calibration
• Sound sample 1: The octave switch and VC wave are controlled by another VCO's triangle and sawtooth wave.
• Sound Sample 2: Same as above with an external sequencer connected.

Sound Sample 3: The pulse wave, heard through a Final Filtre and the VC wave, being modulated by the FF's AD output.
