How the workflow fits together
A complete local workflow from source folder to Organized Library.
The app keeps source inventory, technical analysis, review, safe copying, playback and disk-image preparation inside one desktop workflow while leaving your original source collection available.
- Source Index Inventory supported MIDI/KAR files without moving or renaming the originals.
- Deep MIDI Analysis Resume technical, quality and device analysis across large collections.
- Review and Organized Library Search, inspect uncertain items and copy approved files into a separate organized output.
- Playback and Floppy Image Studio Listen, queue favorites and create IMG disks, manifests, catalogs and PDF reports.
Runs on your computer. Your MIDI archive stays yours.
MIDI Manager is installable desktop software. You choose the source, Organized Library, archive, generated-files and optional SoundFont locations in the application.
The website provides product information, manuals, release notes, downloads, newsletter signup and MIDI Manager First 50 registration. It does not host, scan or process your MIDI archive.
What MIDI Manager can do
- Index large .mid, .midi and .kar collections from folders you choose.
- Search and browse your MIDI archive without relying only on folder names.
- Analyze filenames and metadata before files are organized.
- Review uncertain files instead of blindly copying them.
- Plan safe copy actions before executing them.
- Build a cleaner Organized Library while keeping source files intact.
- Play selected MIDI/KAR files with a SoundFont and FluidSynth.
- Mark favorites/liked files while listening.
- Use playback queue workflows for longer listening sessions.
- Use license-gated advanced organizer and maintenance features when enabled.
- Work locally with files on your computer, NAS or external storage.
- Create and inspect floppy/Gotek IMG disk images and generate disk and catalog reports for vintage keyboard collections.
More evidence before organization decisions.
The 1.0 generation exposes analysis provenance, score explanations and targeted reanalysis/recovery so users can see why a file received its current result.
Uncertain or failed analysis stays visible for review rather than being hidden by a successful-looking summary.
