DEMO PROJECTS
Five editable beats for the current sound model: real TR-808 recordings with a tuned 808 sub bass and conga hook in F minor, 808 sub bass under 909 punch with a cowbell hook, a C minor half-time groove on 909 / 808 recordings with a tuned 909 tom bass, a jazzy F minor session with upright bass, piano chords, vibes and brass (CC0 SESSION kit), and a D minor boom bap flip of chopped soul piano, strings, sax and horns over acoustic drums (SOUL CHOPS kit). Each is a full song of several parts with swing, relative notes and alternating hat channels. Loading replaces the current session; Undo restores it.
Imported v1 sources and original settings are preserved. Playback uses the mono SP engine; earlier stereo effects are not applied.
SAMPLE SOURCES, LICENCES & MODEL STATUS
TR-808 recordings: Michael Fischer; hosted by TidalCycles. The repository declares CC0; the original 1994 README describes them as free. TR-909 analog recordings: Janne G:son Berg, shared by altemark on Freesound under CC BY 4.0; these bundled conversions by 5up-okamura were limited, faded and reduced to 22.05 kHz. CC0 SESSION and SOUL CHOPS instruments and the SOUL CHOPS acoustic drums: Versilian Studios, VSCO 2 Community Edition and Versilian Community Sample Library, CC0; the soul phrase is an original DUST composition played from those single-note recordings and then chopped. DUST resamples every source to a 12-bit nominal 26.04 kHz model. The 909 hybrid uses 808 cymbals because rights to 909 ROM-based cymbals and hats are not cleared. This model has not been calibrated against a physical SP-1200. Full notices.
