Record: pick a loop length (1, 2, 4 or 8 bars) and a tempo. Press ●REC on an instrument lane, then PLAY. The first pass after the count-in starts recording and every pass is a new take until you press STOP or REC again. The lane you are recording is silent; everything else keeps playing, so you can layer.
Pick takes: click a take to choose it (it plays when stopped). PICK plays the chosen take; SHUFFLE picks a random ticked take every pass; CYCLE goes through the ticked takes in order. Untick ✓ to leave a take out of the pool, ★ keeps it when old takes are cleared, × deletes it.
Drums: the blue lane holds patterns (A, B, ...). Click cells in the grid, load a beat, or press ●PADS and tap the pads (keys A S D F G H J K) while it loops. Patterns can be 1–8 bars and tile across the loop.
Songs & sections: the SONG button (top left) makes, opens, renames and deletes songs. A song has as many sections as you like (intro, verse, chorus...); each section is its own loop with its own length, drum patterns and takes. Click a section (or keys 1–9) to work on it; while playing it switches on the next loop.
Arrange: drag sections into the SONG strip (or ADD TO SONG), drag blocks to reorder, − / + for repeats, × to remove. ▶ PLAY SONG plays it start to finish; EXPORT SONG renders it.
Timing: recorded audio is fixed length, so tempo and time signature lock once there are takes. If your takes sound late or early, press CALIBRATE (speaker near the mic) or move Latency fix. Use headphones if you turn MONITOR on.
Drum notes: kick is the bottom row. Pick a loudness (ppp = ghost note ... fff) before clicking, or right-click a note (long-press on a touch screen) to set any velocity 1–127. QUANTISE + STRENGTH decide how hard live hits snap; a second hit on the same spot replaces the first instead of doubling.
Time signatures: each section has its own (TIME menu, or "other..." for anything like 11/8 or 7/8:3+2+2). Swing: 50 % is straight, 66 % is a triplet shuffle, up to 75 %. The menu next to TAP decides what the BPM counts in 6/8, 9/8 and 12/8: quarter notes, or the dotted-quarter pulse you actually feel.
Auto drummer: pick a style and how busy, then RANDOM BEAT (writes a beat and plays) or AUTO DRUMMER (a fresh variation every pass, FILLS before section changes; KEEP THIS BEAT saves one).
Your own drums: IMPORT SAMPLES / IMPORT KIT FOLDER, or drop files on a drum's row name. File names pick the drum (kick, snare, hat...); several files for one drum become soft-to-loud layers. SFZ kits work too.
Mixer: the MIXER button shows the desk: every channel has a parametric EQ (click the little curve), 3 inserts, reverb + echo sends, pan and a fader. Click a block in the SONG strip to mute channels in just that part of the song.
Export: under SETUP. EXPORT LOOP = two passes of the current section, EXPORT SONG = the arranged song, EXPORT STEMS = one WAV per channel in a .zip (each stem includes its own reverb / echo sends, so the stems add up to the mix). Everything is saved in this browser.
Undo: the ↶ ↷ buttons (or Ctrl+Z / Ctrl+Shift+Z) undo and redo drum pattern edits and deleting a take, a pattern, a lane or a section. A deleted take's audio comes back too, until you open another song or reload.
Tuner: TUNER (top bar) listens to the input and shows the note and how many cents sharp or flat you are. It reaches down to a 5-string bass's low B.
FX chains: in a channel's FX panel, CHAIN loads a ready-made amp + cab + reverb (or other) set into the 3 inserts in one click. SAVE CHAIN keeps your own; saved chains work in every song.
