Optomix
Limited WARRANTY: Make Noise warrants this product to be free of defects in materials or construction for a period of one year from the date of purchase (proof of purchase/invoice required). Malfunction resulting from wrong power supply voltages, backwards power cable connection, abuse of the product or any other causes determined by Make Noise to be the fault of the user are not covered by this warranty, and normal service rates will apply.
Installation: The Make Noise Optomix is an electronic signal generator requiring 30 mA of +/- 12V regulated power and properly formatted distribution receptacle to operate. It is designed to be used within the euro format modular synthesizer system. Go to http://www.doepfer.de/a100_man/a100t_e.htm for the details of this format.

OVERVIEW The Optomix is a direct coupled, two channel low pass gate utilizing 4 vactrols to pro-vide simultaneous voltage control over amplitude and frequency content of a signal. It is in essence, a VCFA (Voltage Controlled Filter Amplifier). Additionally the Optomix offers a summing stage complete with an AUXiliary IN allowing for the chaining of multiple units to create larger mixes (this also works well in combination with the modDemix.
Getting Started It’s a VCA, It’s a VCF... The Low Pass Gate operates simultaneously in the amplitude and frequency domains. As the Control Signal becomes more positive, the Amplitude of the processed signal in-creases with the lower frequencies being more quickly amplified than high frequencies. As the Control Signal become less positive, the Amplitude decreases with the high frequencies being attenuated much sooner than the low frequencies.
Patch Ideas The New Bongo: Set up a VCO for two-operator FM by applying a SINE wave to its linear FM input, and patch it to the input of an Optomix. Patch Pressure Points Common Gate OUT to the Optomix Strike Input, and Gate OUT 3 to the DAMP input. Strike the “Bongo” with Touchplate 4 and “dampen” it during or after striking with touchplate 3. Use the DAMP input attenuator to set the amount of damping.
