A Decade Counter takes a clock signal (usually from a square-wave LFO) and shares the clock to 10 outputs, sequentially counting through them. There are reset and disable inputs to allow interesting sequences with more LFOs or other gate/trigger/clock sources, and a /10 output to give a gate output when a step-cycle begins. The maximum step number is 10 but this can then be limited by patching a step output back into the reset input. The DC1 outputs a standard gate signal of +5V.
There are many uses for this module. As well as a 10 step gate sequencer driven by an LFO, a gate signal could be set to drive the module and trigger up to 10 different sounds. With only 2 steps used, the performer can alternate between two different voices per note, which can be useful for creating a bowing effect. The DC1 can also be clocked to frequencies well within the audible range, so the module can act as a sub-oscillator or general audio mangler. If two square-wave oscillators are used with one patched into the clock input and the other patched into the reset input, interesting sync effects can be achieved by changing the pitch of the reset oscillator.
