Become a Master of Time with the 4MS Company QCD Quad Clock Distributor Module
The 4MS QCD is a four-channel, voltage-controlled clock divider and multiplier with a built-in tap tempo function. Each channel can be independently synced to the internal tap clock, to the previous channel, or to an external clock source. Reset jacks are available per channel to allow for precise timing manipulation. With five synchronized outputs and flexible patching options, the QCD is perfect as a master clock source or for generating complex, evolving rhythmic patterns within your modular setup.
- Four CV-controlled clock divider/multiplier channels
- Tap tempo button and five synchronized clock outputs
- Tap clock output runs independently even when other channels are externally clocked
- Create intricate rhythms by cross-patching CV and reset inputs across channels
- Each channel includes: Clock In, Clock Out, Reset In, and Div/Mult CV In
- Divide or multiply incoming clock from ÷32 to ×16 per channel
- Detented Div/Mult knob for accurate integer control
- CV control over Div/Mult amount
- Per-channel Reset input for phase shifting and timing manipulation
- Clock inputs normalized downward: Tap → Red → Black → Blue → Green
- Clock outputs auto-stop when the clock input halts
- Output LEDs blink in time with their corresponding clocks
- 5V buffered square-wave clock outputs; pulse width controllable via expander
- Tap Out jack allows daisy chaining multiple QCDs or other clock modules
- PCB header for direct connection to QPLFO for modulated CV-envelope generation
- Compatible with the QCD Expander (adds pulse width, inverted outputs, CV attenuverters, etc.)
