The piano studio for creators.
Generate original piano pieces, blend songs into seamless medleys with real written modulations, and render it all as a glowing falling-notes video — one tool, no DAW, no LLM in the loop.
MIDI · MusicXML · PDF · MP4 — first project free, no card.
ONE STUDIO · THREE TOOLS
Every step from idea to upload.
01 · GENERATE
Original piano, on demand
Pick a genre, mood, and key — the engine composes a new two-hand piece from learned style profiles. Deterministic seeds, so a take you love is never lost.
Open Generate →02 · BUILD
Medleys with real transitions
Blend 2–4 songs. Medleyo writes the modulations between keys — pivot chords, not hard cuts — or interweaves them as a mashup in one shared key.
Open Builder →03 · VISUALIZE
Falling-notes video, your look
Tune colors, glow, particles, and camera with a live preview, then render a 1080p/60 MP4 ready for YouTube, a church screen, or a lesson.
Open Visualize →THE PIPELINE
From two hymns to a finished video — without leaving the tab.
Everything hands off to the next step. Generate a piece and drop it into a medley. Upload your own recording and Medleyo extracts the MIDI. Any result flows straight into the visualizer.
Bring the music in
Search the public-domain catalog, generate an original piece, or upload audio for MIDI extraction with a piano-roll cleanup editor.
Shape the arrangement
Order your songs, choose medley or mashup, and override any transition — every junction shows exactly how the modulation resolves.
Ship it
Engraved PDF for the piano rack, MusicXML for MuseScore, MIDI for your DAW — and a rendered MP4 with your visual preset.
Your next piece is one seed away.
First project free — generate, blend, and preview without a card.
