Hungry Robot took the modular synthesizer concept and squeezed it into guitar pedal-sized boxes, and their CV Sequencer is one of the smartest utilities in that lineup. It's a straightforward 8-step sequencer that runs on standard 9V power but internally operates at the same +/-12V that eurorack modules use, meaning it patches seamlessly with both guitar pedals and full modular rigs.
The sequencer itself is refreshingly simple. Eight knobs let you set the voltage output for each step, and you feed it an external clock signal to advance through the sequence. A reset button snaps the sequence back to the beginning, while a pause button holds the current step until you release it. The CV output emits whatever voltage you've dialed in on the active step, making it perfect for controlling pitch, filter cutoff, or any other voltage-controlled parameter. It measures just 4.7 by 2.6 by 1.5 inches, so it fits on a desktop or pedalboard without demanding much real estate.
What makes this work in Hungry Robot's ecosystem is the standardized 3.5mm patching and voltage levels. You can chain it with their VCO, VCF, envelope generators, and other modules to build complete synthesizer voices, or use it to sequence parameters across a larger modular setup. The bare-bones approach means no menu diving or screen navigation, just immediate hands-on control. For anyone building a compact modular rig or looking to add sequencing capability to an existing setup without breaking the bank, this hits a sweet spot between simplicity and flexibility.
