Mosaic 's clock in 1U format is used wherever modules with a tempo-related function such as a sequencer, delay effect, sequential switch etc. need to be synchronized with a clock. Two speed ranges are selectable via toggle switch, fine tuning is done with a knob. Since the clock rate can be modulated via control voltage, generic patterns of "indefinable tempo" can result depending on the selected CV source. The pause button interrupts the clock output until it is pressed again.
