Teia Synthesizers OpticTone MK2 Vactrol Multimode-Gate Eurorack Module

Everyone loves a low-pass gate, and here's a great example, based on an original circuit rather than cloning anything vintage. Bongo-tastic!

The OpticTone MK2 is an improved revision of our original module, combining a 12dB multi-mode Vactrol VCF and a Vactrol VCA. This unique circuit is inspired by the distinct characteristics of Vactrols and Lowpass gates, celebrated for their fluid and natural character.

• Vactrol based 12dB multi-mode Voltage Controlled Filter: Lowpass, Bandpass and Highpass.
• Vactrol Based Voltage Controlled Amplifier.
• Crossfade knob to mix the VCA and VCF section.
• Voltage controlled Resonance.
• Improved circuit for Lowpass Gate pluck sounds.
• Ping Input for percussive sounds generation.
• Filter Range switch.
• Switch to set VCA and VCF in Parallel or Series.
• Filter 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.
