OpticTone Vactrol Filter & VCA

The OpticTone is a combination of a 12dB multi-mode Vactrol Filter and a Vactrol Voltage Controlled Amplifier. It is a completely original circuit inspired by the singular nature of Vactrols and their fluid and natural character.

Features:

• Vactrol based 12dB multi-mode Voltage Controlled Filter: Lowpass, Bandpass and Highpass.
• Vactrol Based Voltage Controlled Amplifier.
• Crossfade between VCF and VCA section.
• Voltage controlled Resonance.
• Ping Input for percussive sounds generation.
• Cutoff Frequency polarity inversion switch. Doesn’t change VCA polarity
• Overdrive and Feedback controls.
• Attenuator/inverter knobs on all voltage controlled inputs
• Touch control over Frequency and Amplitude.
• The VCA response is exponential
