iPhone browsers can't go fullscreen from a button. For the full-screen app, tap the Share icon, then Add to Home Screen — SLOOP opens with no browser bars.
GOT ITTout ce qui suit est le vrai firmware, le même que sur le FM-1 : un appui long sur HOME ouvre le menu Dub, SELECT passe d'une page à l'autre (les quatorze : SCR · LGT · AUD · SEQ · SYS puis DUB · SIR · SR2 · SKK · DLY · SND · RDM · PRS · ISO), KNOB 1–4 règlent les lignes en potentiomètres (~300°), OCT+ valide et joue, OCT− ferme.
SLOOP is a four-track groovebox: three synth tracks and a drum track, a 64-step sequencer, songs and punch-in effects. The golden rule: hold a function button and the 16 white keys and four knobs change job — the screen always shows what they do. Tap the same button instead to open its pages; hold a layer and tap HOME to lock it open.
| HOLD | THE 16 WHITE KEYS | KNOBS 1 · 2 · 3 · 4 |
|---|---|---|
| FX | 16 punch-in effects on the whole mix — loops 1/4–1/32, stutter, reverse, tape stop, half speed, filter sweeps, phone, bit crush, alias, gate, echo, tape wobble | FILTER · DUST · DUCK |
| EDIT | erase a sound or note as the loop plays (stopped: from the whole pattern) | SHIFT · LENGTH ×2/½ · TRANSPOSE |
| ARP | note repeat on the grid, recorded as ratchets | RATE 1/8 … 1/64 |
| SEQ | the 16 steps of the page (black keys switch pages) — tap an empty step to set it, a set step clears when released; hold a step and turn a knob for its level or ratchet | SOUND/NOTE · DIV · SWING · LENGTH |
| SCL | any key sets the key of the song | CHORD · SCALE · KEYS · TRANSPOSE |
| GLO | keys 1–4 mute · 5–8 solo · key 16 tap tempo | LEVELS OF TRACKS 1–4 |
| SAVE | keys 1–4 play sections A–D on the next bar · 5–8 save the loop into them · 13 loop/song · 14 record the song · 16 the chain | — |
16 drum sounds on the white keys, kick to cowbell; a black key doubles its left neighbour for fast rolls. Hold OCT−/OCT+ while playing for ghost and hard hits. 37 kits on the PRESETS knob — a sampled acoustic kit and 32 synthesized styles: 808, 909, trap, house, jungle, chiptune and more.
Nine engines — analog, 4-op FM, phase distortion, trio, organ, voice, granular, lo-fi chip, sampler. 68 level-matched factory sounds browsed by kind, 32 user slots. One-key chords in SCL: TRIAD, 7TH, 9TH, SUS4, POWER. Envelope and LFO pages under ENV and LFO.
Save up to four sections A–D (SAVE + keys 5–8), launch them live on the next bar (SAVE + keys 1–4), and record the arrangement as you play it (SAVE + key 14). In song mode, PLAY runs the whole chain.
