Usage and Patch Tips

Basics
A mixer is basically an electrical adder. All the signal inputs are added together and presented at the output. Three of the inputs have attenuators and one does not. You can use a Q125 Signal Processor to attenuate signals before applying them to the unattenuated inputs. Since the signals are added, it's possible to create large signals that may clip which may or may not be desired.

Making New Waveforms
You can create new waveforms by mixing two or more from a single oscillator. The signals will be in phase and create a new stable, unbeating waveform. This can create interesting harmonics that can then be filtered.

Mixing Control Signals
The mixer has DC inputs and outputs which means it can mix slow-moving control signals. This can be helpful when you need to mix an envelope generator output and an oscillator output for use by the filter or other modules that have limited input connectors.
