Clock divider and multiplier module with binary and multi base modes
Polyrhythms is a clock divider and multiplier module for Eurorack, with 12 simultaneous gate outputs: 6 divided and 6 multiplied.
The clock multiplier works best with lower clock frequencies, from LFO into the low audio range. It has a resolution of 1000Hz, which means that the highest frequency it can output is 500Hz.
