Piano Midi Player FAQ
Q: MIDI files don’t play — what’s wrong? Make sure the file is a standard MIDI file (.mid or .midi). Try dragging the file directly onto the Library pane, or use “Add Library Folder” to scan a folder of MIDI files. If you’re hearing no sound, check your Mac’s output volume and that the app’s volume slider isn’t muted.
Q: How do I connect a Bluetooth MIDI keyboard? Click the Bluetooth icon in the sidebar toolbar. This opens the standard macOS Bluetooth MIDI dialog. Put your keyboard in pairing mode, and it will appear for connection. Once paired, select it from the device picker in the bottom-right of the main window.
Q: How do I connect a USB MIDI keyboard? Just plug it in. It will appear automatically in the device picker in the bottom-right of the main window. No drivers needed — Piano Midi Player uses macOS’s built-in MIDI support.
Q: How do I add a folder of MIDI files? Click “Add Library Folder” when the library is empty, or use File → Add Library Folder. The app will scan the folder in the background and add all MIDI files to your library. You can also drag files directly from Finder onto the Library pane.
Q: What are the simplification modes?
- Original — every note exactly as written
- Medium — drops fast grace notes, trims dense chords to three voices
- Easy — just the melody on top and the bass on the bottom
- Beginner — one note per hand at a time, spaced out so you can follow in tempo
Simplification happens in real time — the original MIDI file is never modified.
Q: Can I adjust the playback speed? Yes! Slow any piece down to 25% without changing pitch. Perfect for practicing difficult passages.
Q: Where does Piano Midi Player store my library? Your library database is stored locally on your Mac within the app’s sandboxed container. Your actual MIDI files remain in the folders you selected.
Q: Does Piano Midi Player work on older Macs? Piano Midi Player requires macOS 14.0 (Sonoma) or later. It runs natively on both Apple Silicon and Intel Macs.
Q: How much does Piano Midi Player cost? Piano Midi Player is $9.99 USD on the Mac App Store.
Q: Is an external MIDI keyboard required? No. Piano Midi Player uses the macOS built-in DLS sound engine for playback by default. An external keyboard is optional — use it if you want to play along with your tracks.
