MIDI Medley Maker – Create Seamless Medleys from Multiple MIDI Songs
Turn separate MIDI-KARAOKE files into one polished medley with clean transitions, preserved tempo maps, and intact instruments.
MIDI Medley Maker is a desktop tool that lets you combine multiple MIDI files into a single, performance-ready medley.
You can trim the start/end of each song, reorder parts, insert short pauses, and export a standard MIDI file that plays smoothly in your favorite player or hardware module.

What makes it different?
- Smart cut points (no missing instruments): when you start from the middle of a song, the app re-injects essential channel state (Bank/Program, Volume, Pan, Expression, Sustain, Pitch Wheel and pitch-range RPN) so your sound is complete from the very first beat.
- Tempo & meter preserved: tempo changes, time signatures and key signatures are carried over to keep grooves and barlines aligned.
- Lyrics aware: lyric/text events are merged into two dedicated tracks (Words and Lyrics) so karaoke lines remain readable and tidy.
- Non-destructive workflow: trims, order, and transitions are applied on export; your originals stay untouched.
- GM-friendly output: exports a standard MIDI (SMF) that works with software players and hardware sound modules.
Main features
- Combine unlimited MIDI files into one medley (Pro), choose any order.
- Per-song In/Out points in ticks or seconds.
- Optional pause between songs or basic crossfade (Pro).
- Per-track lyrics consolidation into dedicated text tracks.
- Export as standard MIDI (.mid) with the project’s PPQ.
Who is it for?
Karaoke hosts, live keyboardists, wedding bands, music teachers, and anyone who needs a clean, tempo-true medley built from existing MIDI songs.
How to use it (step by step)

- Preview: play the timeline to check timing and lyrics.

FAQ
Q: The medley plays slower or with missing parts in other tools. Why?
A: That usually comes from cutting mid-song without reinjecting controller/patch state. MIDI Medley Maker fixes this by restoring channel configuration at your chosen start point and pairing all notes correctly.
Q: Can I edit lyrics?
A: The app preserves lyric/text events and writes them to dedicated Words and Lyrics tracks. You can edit them in any MIDI lyric editor if needed.
Q: What format is the export?
A: Standard MIDI file (.mid), compatible with most DAWs, players and hardware modules.
