DDNote Downloads & RevenueDDNote - AI Drum Transcription · App Store

DDNote turns the songs you love into drum practice. The AI listens to a song and writes out the drum score for you, ready to play.

■ From audio files, videos and recordings
Make drum scores from audio files, videos in Photos, or a recording made on the spot. You can also add songs from the share menu of Files, AirDrop and other apps. Up to 20 minutes per song. Transcription runs entirely on your device, so your audio is never uploaded, and it works without a connection.

■ See how to play at a glance
Kit view shows a drummer's hands and feet moving over a drum kit, so you can see what to hit and with which limb, even if you can't read music. Choose a hand-drawn or photo style, and switch to a left-handed kit. In Style you can pick your own photo as the background, adjust its darkness, blur and light, and choose the colour of what flows toward you, as blocks or as a flowing staff.

■ Turn your home into a studio
Hit books, boxes or cushions with your sticks and the microphone hears them and plays drum sounds. Teach the app each thing with a few taps, then play along with a score, or turn what you play into a score. The sound is analysed on your device.

■ Drum notation that's easy to read
Notes played by hand have their stems up and notes played by foot have them down, grouped beat by beat. Bass drum, snare, hi-hat (closed, open and pedal), three toms, crash and ride, plus rim, ride bell and splash. A guide to reading the score is included.

■ Hear the original and the drums
Play the drum part exactly as written, over the original song, or on its own.

■ Practice tools for beginners
Slow down from 1.5x to 0.25x without changing the pitch, loop the bars you want to practise, and speed up a little on each pass. A click follows the song's tempo, with a count-in before playback (none, one bar or two). Choose a beep or a spoken "one, two, three, four", and where the accents fall. The score follows the playback position.

■ Fix the score on the spot
Tap a bar to open it large, then add or remove notes down to 32nd notes. You can always go back to the score as it was before you edited.

■ Write your own phrases
Start from an empty score under Compose on the home screen. Tap the grid to write notes, or tap pads in time with the click to record them.

■ Keep track of practice
See your practice streak and the week's practice on the home screen, and continue from where you left off, at the same position, speed and loop.

■ Export
Print or share the score as a PDF (A4), or export MusicXML and MIDI. The MIDI follows the original's tempo, so it lines up with the song in a DAW. The drum performance can be exported as WAV, and any stretch of Kit view as a vertical (9:16) or wide (16:9) video with sound.

■ Ask the developer directly
Send a song that didn't transcribe well, or a request, straight to the developer from the app's chat. You'll get a notification when there's a reply.
