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
