Clockworks turns rhythm into geometry. Build polyrhythms by layering rotating shapes on a clockface — each shape's sides become evenly-spaced beats, so a triangle and a pentagon played together weave intricate cross-rhythms with zero math. • Layer multiple shapes, each its own voice • 10 instruments — sampled piano, e-piano, guitars, plus synth keys, organ, marimba, vibes and more • Built-in drum kits with a step sequencer • Dozens of scales across many categories for instant melodic results • Scene-based arrangement to evolve your loop over time • Pro FX: 3-band EQ and BPM-synced echo • Export to MIDI, audio (WAV), or sheet music PDF No theory required — just add shapes and listen.
