The DynaMix music synthesizer module is a fast two-channel Low Pass Gate, dynamics manager and mixer, the core of which is derived from our 0-COAST synthesizer. The LEVEL parameter provides simultaneous voltage control over the Amplitude and Frequency content of audio signals, operating as a VCF/A. The DYNMC parameter allows for using audio as a control voltage. It accepts audio signals and converts them into a signal that may increase or decrease the LEVEL parameter thus allowing for side-chaining and ducking. The summing section is complete with an AUXiliary INput allowing for the chaining of multiple MIX units (modDemix, Optomix and RxMx modules) to create large, non-centralized mixes.
