SparkFun SparkPunk Sequencer Kit

  • 5995

The SparkFun SparkPunk Sequencer is a musical control voltage sequencer designed to control the SparkPunk Sound Kit. With the pair, you can create ten-step musical motifs, but there are hidden opportunities in the sequencer: it can be modified and connected to external hardware in clever and interesting ways. The SparkPunk Sequencer cycles among ten steps, reading the slider and switch for each, producing corresponding analog voltages on the output pins. It offers hands-on control, with its array of knobs, sliders, and switches while seamlessly integrating with the SparkPunk Sound Generator for your creative musical enjoyment.

Unlike typical sequencers, this kit offers many tricks and modifications like adjusting Sequence length by connecting solder pads together at the bottom right of the PCB, routing pins to make a one-shot sequence playback, even creating a tempo clock or influencing the analog signals of LEDs. If any of that sounds too simple you can interface with more hardware like synchronizing multiple sequencers and more!

Be aware, the SparkPunk Sequencer comes as a solderable kit that is slightly more complex than most SparkFun soldering kits with a greater variety of components.

Note: The SparkPunk Sound Kit is not included with this kit and will need to be purchased separately.
