Everything your musical ideas need

From the first hum to a polished progression — Melodex keeps every piece of your creative process in one place.

Ideas

One place for every spark

Every idea gets 4 tabs — Recordings, Chords, Notes, Tags. A completion ring shows at a glance what's been captured.

Recordings

Record. Trim. Perfect.

Live waveform recording with precision IN/OUT trim handles. Background playback, loop mode, and lock screen controls.

Chords

Fretboard to symbol and back

Draw shapes on a fretboard — auto-detects chord name across 12 keys. Or build progressions with 40+ chord qualities and a custom symbol keyboard.

Tags & Search

Find it in seconds

Label ideas with key signature, feel, genre, and instrument. 128 presets plus custom tags. Fuzzy search by name or filter by tag from the home screen.

Beyond songwriting

Your practice journal,
always with you

Melodex is just as powerful as a daily practice log. Capture drills, document techniques, track your progress — and hear exactly how far you've come months later.

🎸
Technique drills

Record yourself nailing a new riff or technique. Log the chord shapes or fingerings right alongside it so you never forget the details.

📈
Hear your progress

Date-stamped recordings let you compare yourself from day one to day ninety. Motivation you can actually listen to.

🗓️
Structured routines

Build practice routines as Ideas — warm-ups, scales, songs in progress — and revisit them exactly as you left them.

Your ideas, everywhere you are

Melodex works great offline and even better with an account. Sign up once and your entire library — audio recordings, chord progressions, notes, and tags — stays in sync across every device you own. Export your audio at any time.
