The Shuffling Clock Multiplier from 4ms is the speedy cousin of the Rotating Clock Divider. The SCM has inputs for CV Rotate and CV Shuffle, which are connected in this video to the X and Y outputs of a joystick controller. In normal mode, the SCM outputs 8 clock signals that are exactly 1-8 times faster than the clock input (which is coming from a tap tempo module in this video).

The CV Shuffle drops beats out, dropping more pulses as more CV is applied. So at 0V there are no beats dropped, e.g. on the x8 jack there's a steady 1/8 note pulse. At 1V some notes drop out, e.g. we may get three 1/8 notes followed by two rests and then three more 1/8 notes, and this pattern repeats each measure. At maximum CV input we get only the down beat (first note of the measure)

The CV Rotate works like it does on the RCD (applying a CV routes the clock outputs to different jacks).

The sounds are generated by an EH Space Drum, an Andromeda mkII snare module, and a bass drum module by Jeannot

More to come!!

An alpha version of a 4HP Tap Tempo Eurorack module triggering a drum module. At the end of the video a 4ms Shuffling Clock Multiplier beta version (which has a tap tempo clock, too) is running between the tap tempo module and the drum module. These two tap tempo clocks in series create a roll effect that resolves on the downbeat...

The Tap Tempo module has a tap button that can set the tempo and/or output direct pulses. A 3-position switch selects the mode:
-Down position: tap button directly outputs pulses (no internal clock)
-Middle position: tap button sets tempo of internal clock
-Up position: internal clock is locked in tempo, tap button outputs additional pulses
