SparkFun SparkPunk Sequencer Kit
The SparkFun SparkPunk Sequencer is a ten-step analogue control voltage sequencer designed to pair with the SparkPunk Sound Kit. Each step has its own slider and switch, producing corresponding analogue voltages on the output pins. With its array of knobs, sliders, and switches, it provides hands-on control for creating musical motifs and experimental sounds.
Built around the CD4017 decade counter, the sequencer offers plenty of modification options — adjust sequence length via solder pads, configure one-shot playback, create tempo clocks, or synchronise multiple sequencers together. It's a more complex soldering kit than most, with a wide variety of components.
Key Features
- 10-Step Sequencer – CD4017-based with adjustable 1–10 step length
- Individual Step Controls – Each step has a slide potentiometer and SPDT switch
- Tempo and Slide Control – Rotary pots for tempo and portamento
- Modifiable Design – Solder pads for sequence length, one-shot mode, and external sync
- SparkPunk Compatible – Connects directly to the SparkPunk Sound Kit
- 9 V Battery Powered – Single battery powers both the sequencer and sound generator
