Perform
Perform mode (the hand icon) is spool.’s live surface. No editing, no menus — just the controls you want under your fingers while the tape rolls.
Tape moves
A row of chips rides the top of the screen for playing the tape itself:
| Chip | What it does |
|---|---|
| ◀ CLIP / CLIP ▶ | Hop the loop backwards or forwards along the tape. |
| LOOP | Toggle the loop on and off. |
| BREAK | Hold it — the tape brakes to silence, and snaps back the moment you let go. |
| REV | Hold it — the tape runs backwards while held. |
| CHOP | Hold it — a tempo-locked stutter chops whatever is playing. |
BREAK, REV and CHOP are momentary — they’re effects you play, not switches you set. Tap-hold-release in rhythm.
Memos — M1 and M2
Memos snapshot a control so you can snap back to it live:
- Tap STORE to arm it.
- Tap M1 or M2 to capture the current setting into that slot (a dot marks a filled memo).
- From then on, hold M1 or M2 to recall it — and release to let go.
The channel strips
Four faders — one per tape track, each with a live meter — sit mid-screen for mixing on the fly. Each strip has MUTE (a toggle) and SOLO (momentary: solo lasts while your finger is down).
The double keyboard
Perform stacks two keyboard rows — a low row and a high row — so bass and lead sit under your hands at once. Each row has its own scroll grip (marked ↑ and ↓) to slide it independently.
Everything else works as usual: favorites switch sounds live, HOLD latches, and the transport keeps recording available so you can capture the jam.
