If you’re new to DIY synthesizer building, you might have encountered this problem:

You just set up your first VCO on a breadboard, spent quite some time troubleshooting the stubborn device – and then you realize you have nothing to actually control it with. OR if you already have a decent modular setup but still haven’t found a simple, hands-on sequencer – here’s a compact yet versatile 5-step sequencer with adjustable sequence length, per-step gate status, and output range! It works both from an internal and external clock and has a reset input for more complex sequences if several sequencers are chained together. It also works as a waveshaper when clocked at audio rate.
