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.
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
