4ms SCM Plus [SCM+]

The SCM Plus is a clock multiplier with eight gate outputs and complex beat manipulation features. It combines the classic Shuffling Clock Multiplier (SCM) and SCM Breakout (SCMBO) into a single module using higher precision hardware than its predecessors. SCM Plus User Manual v1.0 Features Eight gate outputs, each multiplying up to x32 Five slipped/shuffled/skipped clock outputs and three steady clock outputs Five knobs with CV jacks: Rotate shifts multiply-by amount Slip causes particular beats to land ahead in time Shuffle selects which beats are affected by Slip Skip omits certain beats in a pattern Pulse Width controls width of output pulses Resync trigger input resets the slip/shuffle/skip counters 4x Fast button and gate jack increase multiply-by amount by a factor of four Mute button and gate jack stop all outputs Save Clock feature restores last saved tempo when powering up Clock Bus jumper allows module to receive tempo from other modules over the power bus Free Run jumper allows unit to operate without an external clock LED dimmer trimpot allows for custom LED brightness 12HP Eurorack module Specs Electrical and Mechanical Specifications 12HP Eurorack format module 0.95” (24mm) maximum depth (includes power cable) 16-pin Eurorack power header Power consumption +12V: 52mA max -12V: 15mA Clock Input 2.5V threshold 40kHz maximum Clock Outputs 12V gate outputs, rise/fall time approximately 1us 40kHz maximum Jitter (x1 output): max 30µs < 120BPM, max 5µs >= 120BPM Latency (clock in to x1 output): 8µs worst-case, 3.5µs typical CV Inputs: Rotate, Slip: Knob attenuates jack signal.
