DEMO PROJECTS

Three 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, and a C minor half-time groove. Each is a full song of several parts with swing, relative notes and alternating hat channels. Loading replaces the current session; Undo restores it.

The SP sound engine stays the same. Classic adds the original memory limits.
CHANNEL PAIRS / DYNAMIC ALLOCATION
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. DUST resamples both sources 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.

Make some noise.

Tap a pad to unlock audio. PLAY starts the segment; RECORD captures your hits. Choose bank A–D and edit its 16 steps. Hold a pad to open its sample editor.

Your project saves automatically on this device. Import audio opens the sampling editor: choose a region, capture at 1×, 1.35×, 2× or 4×, then restore pitch on playback. Use manual markers, equal slices or transients to chop onto pads. Undo restores the whole assignment. Project export includes samples and original sources; WAV export uses the same audio engine as playback. Import older DUST projects here; your original session data is preserved during migration.

CHOP slices the sample on the selected pad. Hold a step to shape it: velocity, pitch, chance and ratchet. NOTE REPEAT retriggers a held pad on the sequencer grid; TOUCH LEVEL makes hits lower on a pad stronger; CLICK is a metronome that never reaches the WAV export. SOLO and MUTE affect playback and export. Pads on the same channel cut each other, like the SP-1200, so put open and closed hats on one channel and keep that pair off in Project for a choke. New projects follow the firmware: a pair set to dynamic allocation alternates its two channels on every hit, whichever sound is played and whether or not the other channel is busy, so the third hit cuts the first. Older projects keep their previous allocation.

Earlier sound profiles: DECAY has 32 SP-1200 settings, 00 to 31. FULL plays the entire sample. Shorter settings use the hardware hold and stepped fade. Saved decay percentages keep their previous sound until you move that slider.

MULTIPITCH presets are +7, +6, +4, +2, 0, −1, −3, −5 semitones from left to right. In earlier profiles, choose PITCH or DECAY under MULTIPITCH; new projects use the separate SOUND PARAMETER setting. Choose OFF to return to ordinary pads; tapping the active MULTIPITCH or MULTILEVEL button also switches it off. DECAY plays eight decay lengths; FULL uses a centre setting of 16. MULTILEVEL runs from soft to loud through eight SP level codes. Recording and NOTE REPEAT keep these variations. Older saved hits keep their sound; reselect a pad mode to adopt the new presets.

New projects use firmware MIX steps. TOUCH LEVEL maps the gesture to hardware levels; dynamic hits override MultiLevel. In SOUND, choose TUNE or DECAY, set INIT 00–31, and use MIX → TUNE / DECAY for relative key offsets. INIT changes already recorded relative notes. DEFAULT DECAY affects all tuned sounds. FULL LENGTH bypasses decay as a DUST extension. MultiPitch has its own OFF/ON selector. Older projects retain their earlier controls. PROJECT → DEMO PROJECTS loads one of three editable beats; Undo restores your session.

Mode keys switch the editor in the middle: SEQUENCE for steps, SOUND for the selected pad, MIX for pad modes and sliders, SONG and PROJECT. Pads and transport always stay at the bottom.

Keys: 1–4 and Q–R play the current bank, A–F and Z–V the next bank. Space plays or stops, Shift+R records, Esc stops, Ctrl/Cmd+Z undoes.
