SCM Plus

Shuffling Clock Multiplier & Breakout

The SCM Plus is a clock multiplier with eight gate outputs and complex beat manipulation features, using higher precision hardware than its predecessors.
SCM Plus 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 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. Full range: 0V to +3.3V
• Shuffle, Skip, PW: Knob offsets jack signal. Full range: -5V to +5V

Gate Inputs:
• 4x Fast, Mute: 2.5V threshold. Button toggles state.
