Used 4MS QCD Quad Clock Distributor: the rhythmic control center of your Eurorack system

This 4MS QCD Quad Clock Distributor is a used product that has been thoroughly tested and is in perfect working order. It is one of the most popular clock modules in the Eurorack world thanks to its ability to distribute, multiply, and divide the clock with independent CV control across four channels, offering extremely flexible synchronization management for the entire modular system.

Four independent channels with CV control

Each channel features a Clock input, Clock output, Reset input, and a dedicated CV input for controlling time division or multiplication. The clock ratio can be adjusted from ÷32 up to ×16, allowing you to easily create complex rhythms, polyrhythms, and perfectly synchronized temporal variations.

Tap Tempo and Master Clock

The built-in Tap Tempo button allows you to quickly set the system’s master tempo. The dedicated Tap Clock output continues to generate the master clock even when other channels are using external synchronization sources, making the QCD an excellent master clock for any Eurorack setup.

Advanced Rhythmic Patterns and Generative Patches

Thanks to the ability to connect channels together via the Div/Mult CV and Reset inputs, the QCD lets you create extremely intricate rhythmic structures, evolving grooves, and generative sequences while maintaining complete control over synchronization at all times.

Compatible with the 4MS ecosystem

The module can be expanded using the QCD Expander, which adds Pulse Width, Inverted Gate, Shuffle, and CV attenuators, or connected directly to the Quad Pingable LFO to achieve four synchronized and fully modulatable envelopes.

Professional-grade construction for live and studio use

All potentiometers feature metal shafts with locking nuts, ensuring high durability even during intensive use. Dedicated LEDs clearly display the tempo for each channel, making it easier to work both in the studio and during live performances.
