Features

4 H.P. Eurorack format
Divide-by-1 to Divide-by-64, on 8 output jacks
CV Rotate jack to shift divide-by amount on each jack
CV Reset jack to reset/re-sync all jacks
Optional break-out panels to expand functionality (MIDI, Auto-reset, selectable Divide-by range, Gate/Trigger, Up/Down-counting)

Jacks

Clock Input (5V to 15V clock, rising edge triggered), max 3kHz
CV Rotate (0V to +5V input)
CV Reset (5V to 15V trigger)
Divided Clock Outputs (8 jacks):
- Divide-by-(1+R)
- Divide-by-(2+R)
- Divide-by-(3+R)
- Divide-by-(4+R)
- Divide-by-(5+R)
- Divide-by-(6+R)
- Divide-by-(7+R)
- Divide-by-(8+R)
...where R is the CV Rotation.
Selectable Gate/Trigger mode:
Selectable Divide range up to Divide-by-64:
Two jumper pins on the back can be pre-set with jumpers plugs, or used with (forthcoming) breakout panel.
Selectable Auto-reset:
Auto-reset will reset the divide counter every 16/24/32 clocks, which keeps the beats more "dance-able" even when using the "weird" clock divisions (3/5/6/7/9/10/11/etc..) Two jumper pins on the back can be pre-set with jumpers plugs, or used with (forthcoming) breakout panel.
