What Sill does
- Press PLAY and Sill writes and performs a 90s eurodance song with stabs, bass, hook, drums and choir.
- Ten styles across CLUB and RADIO bring their own tempo, sounds, key, chord loop, groove and space.
- ALGORITHM picks a new song in the same style, and the same number always brings that song back.
- Four knobs steer LIFT, PUMP, VOX and ENERGY, while PRESETS changes style on the next bar line.
- REC drops the track to held stabs for a break, and SEQ pushes the whole song up a semitone.
- The keys play the hook live, snapped to the scale, with their LEDs glowing on the chord's notes.
- STABS, BASS and HOOK each offer sixteen sounds, with kits from Sill's own one-shots or a drum engine.
- Eight sets on the SETS page store whole songs, and settings save themselves while stopped.
Its modes
- PLAY
