An electronic drum kit with MIDI output (USB) is recommended but not required. You can also use your computer keyboard to try the app.
Getting Started
- Download and install Score Drummer for your platform
- Connect your electronic drum kit via USB MIDI. The app auto-detects it
- If the kit is not mapped correctly, open Settings, click "Drum MIDI Mapping...", and assign each pad to the right drum sound
- Import a MIDI or Guitar Pro file of the song you want to practice
- Hit play and start drumming. You'll see real-time feedback on every hit
- Use Practice Mode to slow down and loop tricky sections, or Performance Mode for scored play-throughs
Frequently Asked Questions
What MIDI controllers work with Score Drummer?
Any electronic drum kit or MIDI controller that sends standard MIDI notes over USB. Score Drummer auto-detects connected MIDI devices at startup and supports hot-plug. Just plug in and play.
Can I practice without a drum kit?
Yes! Score Drummer includes a "Use Computer Keyboard" mode that maps keyboard keys to drum instruments. It's a great way to try the app or practice reading along with a song.
What file formats are supported?
Score Drummer imports standard MIDI files (.mid, .midi) and Guitar Pro files (.gp, .gp3, .gp4, .gp5, .gpx). The app auto-detects drum tracks using name-based, channel-based, and content-based analysis. For audio backing tracks (Pro feature), WAV, AIFF, MP3, and other common audio formats are supported.
How is timing evaluated?
Every hit you play is compared to the expected note in the score and classified into one of six tiers: Perfect (≤20ms), Good (≤50ms), Early (≤100ms), Late (≤100ms), Miss (not hit), or Extra (hit with no matching note).
Can I use my own drum sounds?
For now, the user's live drum input always uses the bundled MuldjordKit SoundFont. Custom SoundFonts do not change the played drum kit sounds in this version of the app.
Can I use custom SoundFonts?
Yes. Pro users can load custom SoundFont files (.sf2/.sf3) for MIDI backing-track playback, so MIDI files can be reproduced with all instruments. The user's live drum input still uses the bundled MuldjordKit SoundFont.
How do I transfer songs between devices?
Pro users can export their entire song library as a .sdlib archive file, then import it on another device. The archive includes all songs, mixer settings, and audio file references. Statistics and replays can also be optionally exported along with the songs.
What's the difference between Practice and Performance mode?
Practice Mode lets you adjust tempo (10%-100%) and loop bar ranges. Performance Mode plays the song at full tempo and gives you a letter grade with detailed stats at the end.
How do audio backing tracks stay in sync?
Pro users can run Auto-Sync to align audio with the MIDI or Guitar Pro score, then adjust the result manually with marker handles. Analyze drift can expose extra editable markers only when the audio shows systematic tempo drift.
Can I review past performances?
Performance runs are saved to history. Pro users can view progress charts, open detailed recaps, and replay recorded takes with hit-quality markers across the score.
Is my data private?
Absolutely. All data stays on your device. No analytics, no tracking, no cloud services. See our privacy policy for details.
