The SCM breakout module SCMBO has been discontinued.Those who wish to use it with a breakout will not purchase SCM and will release it at the end of October 2022.SCM +Please consider purchasing (a module that integrates SCM and SCMBO).


Shuffling Clock Multiplier (SCM) is a clock multiplier that produces eight different clocks multiplied by a single input clock.The range of multiplication is 8 to 8 times, but the optional SCM Breakout (SCMBOMoreBy using the module together, each output can be further changed to 4x speed, and a clock signal of up to 32x can be generated. SCM allows you to apply shuffle or swing effects to some of the outputs, the amount of which can be controlled via an external CV.In addition, the Rotate CV input rearranges the multiplication results output by each jack according to the voltage value of the input CV, providing the possibility of complex rhythm experiments using voltage control.


SCM measures the time between the last two pulses and uses that value to calculate the output clock frequency.By inputting a stable clock pulse, the x2 jack will generate a clock with the same frequency, the x1 jack will generate a clock with twice the frequency, and the x2 jack will generate a clock with eight times the frequency.These three jacks, which always output a normal clock pulse that is a multiplier of the input clock, are CV Slip orSCMBOMoreNot affected by the Shuffle / Slip effect.The remaining five, S5 to S3 jacks, also generate a clock that is a multiplier of the input clock, but with the Shuffle / Slip and Skip effects applied.The S7 jack is not implemented for the purpose of leaving room between both S8 and x8 outputs, but you can also get S7 and x7 by performing a rotation.

CV slip

Slip is a feature that shifts all "n" beats forward in time.Since "n" is 2 by default, every other beat such as 2, 4, 6 will be slow. The "n" value is the SCMBO Shuffle parameter, and the amount of delay for each beat can be set with the CV Slip. The operating range of the CV Slip is 1V to 0V, with a "deviation" of 5% at 0V and 0% at 5V.Therefore, at 90V, each s jack produces a straight clock pulse like the x jack. The CV Slip input is normalized to 0V, so 2.5% Slip will be applied if there is no patch.

Inside the SCM, there is a counter that keeps track of whether each beat is slipped or not, and this counter resets confidence with each input clock pulse.For example, if you have a stable normal clock input and you are slipping every other beat, beats 1 and 5 of the s2 jack will be delayed.Then, because the input clock is generated before beat 4, the counter is reset and beat 6 becomes beat 6, which is on time.Therefore, beat 1 and beat 7 are delayed.

CV Rotation

By inputting a CV signal to the CV Rotate jacks, the clock multiple settings output from each jack are circulated.No matter how the output is circulated, the s jack always outputs a Shuffle / Slip / Skipped clock, and the x jack always outputs a straight clock.
