ChordMapMidi vs Mediant

ChordMapMidi allows you to explore chords and chord progressions in both major and minor keys, one finger tap at a time. Note: ChordMapMidi is a MIDI controller. It doesn't create sound on its own. It sends note information to synthesizer apps you have on your device. ChordMapMidi is useful for songwriters, MIDI musicians, music educators... especially in places where the only instrument you have is the phone in your pocket. Have fun exploring chords and progressions!

Chord progressions, on tap. Mediant writes musically sound chord progressions. Pick a key and mode, tap Generate, and get functional progressions — real tonic / subdominant / dominant motion and proper cadences — that you can audition, reorder, and drop straight into your DAW. HOW IT WORKS • Pick a key, mode, length, and voicing, then tap Generate. Mediant offers several progressions, ranked best first — tap Regenerate to cycle them. • Two dials shape the mood: Brightness (major ↔ modal) and Tension — from plain diatonic triads up through 7ths, secondary dominants, borrowed chords, mode mixture, and tritone subs. • Tap any chord to swap it from a full palette, or move, duplicate, and delete. Build a whole progression by hand if you like. • Harmonize a melody: draw one on the grid or import a MIDI or MusicXML file, and Mediant writes the chords underneath it. WHAT'S INSIDE • Producer-friendly voicings — spread pads, close, open, and drop-2 — with smooth voice-leading between chords. • A live chord-symbol notation preview on a staff. • MIDI and MusicXML export — for your DAW, or MuseScore, Sibelius, Dorico, and Finale. • Fully offline. No account, no sign-in, no ads, no in-app purchases. • Private by design — Mediant collects nothing. Your music never leaves your device unless you export it. Mediant is by Songdeed.
