The Q156 module combines a signal comparator, LFO, VCA and AC Mixer/Coupler in a single-wide module.
The Comparator section compares two signals and produces a gate output when the + signal is higher than the - signal. A single signal can also be compared to a fixed voltage set by the knob. Produce random gates, pulsing gates, convert audio into gates, create effects that apply to only a certain range of notes, and so much more.
The second section is an AC coupler and mixer. Remove DC voltage from a signal, convert gates from the comparator section or from the Q173 Gate Math module into audio, and mix signals.
The third section is a general purpose utility LFO. Triangle and square wave outputs are available. Patch the triangle wave into the comparator section to create PWM.
The bottom section is a simple VCA. Patch the LFO into the VCA to create tremolo, or use an envelope to create decaying vibrato - the possibilities are endless.
