An analog VCO with a unique wave shaping circuit. Based on the 1970s Kobol synthesizers, the WFM output provides a continuously variable wave shape from triangle to saw to modulated pulse, with many interesting points in between. Voltage control over wave shape and output amplitude allow for wide timbral variations.


• Three simultaneous waveform outputs: Triangle, Pulse, and WFM
• FM input with attenuator, switchable between linear and exponential
• V/Oct input
• Sync input
• WFM "MOD" input with attenuator
• WFM "LEVEL" input
• WFM variable pulse input
• 10hz-25khz frequency range
• 8+ octaves tracking

Technical Specifications

• 8hp
• 35mm depth
• Current draw: 65mA/65mA  +12v/-12v

• Reverse power polarity protection
