Percussive snappy (classic Buchla Bongo) dual low pass gate from the innovators at Make Noise, Optomix has the sound you want for west coast leaning sythesists and more in 8hp.

Excellent working condition with a few tiny dings on the faceplates from the previous owner. Comes with alternative silver faceplate (black faceplate installed) and power cable.

The Optomix from Make Noise is a dual Low Pass Gate and Mixer. A low pass gate is a circuit which utilizes both amplitude modulation and filtering. It uses a vactrol component, which uses lights and optical sensors within the circuit, providing a very characteristic response shape. This is most famously demonstrated with the "Buchla Bongo" effect. An interesting addition to the newest version of the Optomix allows the volume curve to be used directly as CV, providing two snappy envelopes if the two audio inputs are not used. Finally, there is an Auxiliary input, which is summed to the mixer, giving three mix channels.
