Loop Seeder

Build chords, melody, bass and drums. Export a WAV loop.

STEP 1 — MAP A SONG (OPTIONAL — DROP A TRACK YOU OWN, LIFT ITS SKELETON)

DROP A SONG HERE OR CLICK TO BROWSE — MP3 / WAV / M4A / OGG / FLAC. IT NEVER LEAVES YOUR BROWSER.

WE'LL PULL OUT THE KEY, TEMPO, THE MOST-REPEATED CHORD LOOP AND ITS MELODY LINE — THEN LOAD THEM INTO THE STEPS BELOW FOR YOU TO BEND.

STEP 4 — CHORDS, ONE PER BAR

TAP A PRESET TO FILL THE BARS, HIT RANDOM FOR A PROGRESSION YOU WOULDN'T HAVE PICKED, THEN POKE ANY CHORD SELECT TO TWEAK IT. NUMERALS FOLLOW THE SCALE YOU PICKED.

STEP 5 — MELODY (OPTIONAL — CLICK CELLS TO ADD NOTES)

ROWS ARE NOTES OF THE SCALE, TWO OCTAVES, TOP TO BOTTOM. THE PATTERN REPEATS EVERY MELODY LENGTH. CLICK TO ADD OR REMOVE A NOTE; FADED CELLS ARE A HELD NOTE — CLICK ONE TO CUT IT SHORT THERE. DENSITY = HOW BUSY, MOTION = STEPWISE VS LEAPY.

STEP 6 — RENDER THE LOOP

SET A KEY, PICK A PROGRESSION, RENDER.
