SQUELCH

A pocket acid house studio: a 303-style bassline synth and a 909-style drum machine. Press space and start twisting CUTOFF.

MAKE A LOOP IN 30 SECONDS

• Hit a preset, or ⚄ RANDOM LINE + ⚄ RANDOM BEAT. The 909 / 808 switch in the rhythm panel swaps the whole drum kit's sound — 909 punches, 808 booms (and its ride row becomes a cowbell).
• Press play, then sweep CUTOFF and RESO — that's the acid.
• Click the piano roll to place notes; click a note again to remove it.
• ACCENT lane (orange) makes a step bark. SLIDE lane (mint) glides it into the next note — the signature 303 move.
• ∞ EVOLVE turns it into a self-playing machine: press play, switch it on, and the groove keeps rewriting itself — filter sweeps, line mutations, drum changes, breakdowns. Leave it running.

BUILD A TRACK

• Patterns A–H are separate loops. COPY / PASTE to make variations.
• Add patterns to the track strip, switch to PLAY TRACK, and they play in sequence (click a chip to remove it).
• While playing, clicking a pattern slot queues it for the next bar.

PERFORM (LIVE / TOUCH)

• PERFORM opens a full-screen live surface with big touch targets — built for tablets, works with a mouse too.
• The big XY pad is CUTOFF × RESO; the second is ENV MOD × DECAY. On a touchscreen you can ride both at once.
• Hold the THROW pads for momentary FX — delay flood, reverb wash, drive push — they snap back on release.
• Big pads launch patterns (next bar) and mute drums. TAP sets the tempo (tap 3+ times on the beat).
• NUDGE is a beatmatching tool: while held, the tempo shifts ±6 BPM so the groove slips forward or back in phase, then snaps back to the set BPM on release — like pushing or dragging a turntable platter. Against another track it pulls the beats into line; listening solo it's meant to be barely audible, and it only acts while playing.
• The screen stays awake while performing; ⛶ goes fullscreen.
• The SAMPLE row fires one-shots over the track — crash, hoover, stab, riser and friends, all captured by the recorder. Load your own sound onto any pad with the + button under it (on iPad choose “Choose File” in the sheet — or nicer: open the Files app in Split View and drag audio straight onto a pad; on desktop just drag a file onto the pad). Max 10s — it stays in your browser, nothing uploads; × restores the built-in. shift+1–8 fires pads from the keyboard.

RECORD

● records the master output live — including your knob tweaks — and offers the audio file when you stop. SAVE SESSION exports everything as a file you can LOAD later.
