Chippo
Key Features
- Generates melody, bass, kick, snare, and hi-hat patterns from a compact control set
- Root, scale, density, and step-length controls help steer the generated musical material
- Melody and bass sections include shape, envelope, octave, volume, and related performance controls
- Drum section provides separate generators for kick, snare, and hat parts
- Manual step editing allows smaller changes after a generated pattern lands close to the idea
- Built with Cycling '74 RNBO and JUCE, with the project code shared publicly on GitHub
Description
Chippo is a playful chiptune-inspired instrument and pattern generator from Emily Hopkins, built in collaboration with Cycling '74. It creates melody, bass, kick, snare, and hi-hat parts from simple controls for root, scale, density, and sequence length, then lets you regenerate or edit the resulting steps.
The workflow is closer to a compact retro sketch box than a traditional synth preset machine. You choose a musical direction, let Chippo fill in jerky 8-bit-style movement, then keep the happy accidents or nudge the step grid until the pattern sits better.
That makes it useful when a blank piano roll is slowing you down. The melody and bass sections can throw out odd intervals and arcade-like motion, while the drum generators create kick, snare, and hat ideas that can push a loop away from predictable four-bar habits.
The main limitation is intentional: Chippo does not generate MIDI. Treat it as a focused sound source for quick chiptune hooks, texture beds, and resampling passes, especially if you like printing strange pattern ideas and processing them with other effects.

Frequently Asked Questions
Does Chippo generate MIDI?
No. Emily Hopkins' official page describes Chippo as intentionally simple and says it does not generate MIDI. It is better treated as a self-contained chiptune instrument for generating and editing internal patterns.
What parts can Chippo generate?
Chippo has separate melody, bass, and drums sections. The drum area includes individual generation controls for kick, snare, and hat patterns, while the melodic sections can be shaped with pitch, scale, density, steps, and synthesis controls.
Who built Chippo?
Chippo is credited to Emily Hopkins in collaboration with Cycling '74. The official page says the concept was implemented with RNBO, exported as a VST, and then finished with a JUCE interface.
Can the generated patterns be edited?
Yes. The release coverage notes that you can regenerate sections when a pattern misses, or manually adjust steps when the generated idea is close but needs smaller changes.
