Rubicon

David Dixon's analogue triangle core VCO in 18 HP, capable of through-zero frequency modulation, with eight waveforms at once, some at multiples or divisions of its frequency.

Key features

• Through-zero FM through a VCA, its depth under INDEX control
• SYMMETRY from reverse to forward, under CV
• Sine or sigmoid, triangle, saw, double saw, zigzag, square, pulse and sub outputs
• Soft and hard sync, its reset rising or falling
• Exponential FM and PWM inputs; LFO or VCO range
