A multi-mode divider for clock and audio signals
It can be used either for dividing clock signals (e.g. from an LFO, BEATDIVIDER) for rhythmical purposes but also for audio signals - in this case you get subharmonics / lower octaves squarewaves at the outputs, which can be mixed or used separately.
The module has eight outputs which - depending on the selected division mode - provide different division factors of the input signal:
These merchants probably sell this module. Huh?
