DIY kit maker CuriousInventor has introduced a new music sequencer kit, called the Voice of Saturn, that looks like an inexpensive way to get into analog sequencing.
This is a 10 step analog sequencer, which basically steps through 10 different voltage levels that are set by the black knobs. The output control voltage and trigger signals are typically used to control pitch, filters, drum triggers and an endless number of other parameters on other synths.
It’s based on a decade counter chip (CD4017) driven by a 555 timer (clock), although it can also use an external clock signal. The sequence can be shortened by connecting an eighth-inch audio cable from the reset jack on top to one of the step’s jacks. It features both a gate output and a S-trigger output for Moog synths.
Amazingly, the kit is just $125. It’s currently out of stock, no wonder why!

Here’s a video that shows you how this bad boy works:
- the 10 step sequence can be shortened by connecting a 1/8″ male-male audio cable from a step jack to the main reset jack.
- The internal clock can be bypassed so that an external clock can drive the VoS Sequencer. We’re not entirely sure what types of clocks it’s compatible with, however. The internal clock can also be output to drive another device.
- Features both a Gate out and S-Trigger out for older Moogs.
- Battery powered: you may want to add a fixed voltage supply to keep the CV levels from drifting as the battery dies, although we’ve found it to last a long time.
- When the clock switch is off, the hold switch can be used to manually step through the sequence.
