Regular price $1,690.00 HKD Sale


The Optomix is a dual voltage-controlled vactrol Low Pass Gate module. Insert a sound source into the input, then use the CTRL knob or CV to control the dynamics. Aside from control voltages, it can also accept gates or triggers through the unique STRIKE input for more percussive sounds, including the classic Buchla Bongo sound. The DAMP parameters allow fine-tuning of the character of the low pass gate. The two low pass gate channels can also be summed together along with a third AUX channel input, making it a three-channel mixer. Normalized and flexible signal paths make the Optomix easy to integrate with other modules or systems.
