Learning drum parts by ear no longer has to take hours. Drummer Notes analyzes any song you own, isolates the drum track using state-of-the-art on-device AI, and transcribes it into crisp, readable drum sheet music. Then, step into the interactive practice studio: mute the original drum track to play along with the band, slow down tempo without changing pitch, and loop difficult fills until you nail them. No cloud uploads. No subscription required to start. 100% private and works completely offline. ================================== TURN ANY SONG INTO DRUM SHEET MUSIC ================================== • Instant AI Drum Transcription: Import MP3 or AAC files from the Files app, or import directly from your local Apple Music library. • Studio-Grade Drum Stem Isolation: Advanced neural networks cleanly separate drums, bass, vocals, and other instruments right on your iPhone or iPad. • Professional Drum Notation: Clean percussion clef notation with standardized drum kit positions for kick, snare, hi-hat (closed/open), toms, ride, and crash cymbals. ================================== ADAPTIVE DIFFICULTY LEVELS ================================== Learning a song shouldn't be all-or-nothing. With one tap, adjust the score to match your exact skill: • Beginner: Simplifies the beat to kick, snare, and steady quarter-note hi-hats. Eliminates complex ghost notes and 16th-note runs so you can groove immediately. • Intermediate: Adds crash, ride, and 8th-note variations while maintaining clean, readable bars. • Advanced: The complete, uncompromised transcription including ghost notes, intricate cymbal patterns, and lightning fills. ================================== YOUR PERSONAL PLAY-ALONG STUDIO ================================== • Mute the Drums (Minus-One Tracks): Silence the recorded drum track and play in the drummer’s seat alongside the real singer, guitar, and bass! • Pitch-Preserving Tempo Control: Slow down from 100% down to 50% speed without altering pitch or introducing robotic distortion. • Practice Loops: Set custom start and end loop markers to drill tricky fills and transitions measure by measure. • Synchronized Beat Highlighting: Follow the score with real-time visual beat tracking that stays locked to playback. • Play Notes Synthesizer: Hear how the notated drum score sounds with built-in drum audio. • 16th-Note Grid Quantization: Snap complex syncopations to a clean rhythmic grid whenever you need strict timing reference. ================================== EXPORT & PRINT ================================== • High-Resolution PDF Export: Turn your custom transcriptions into beautiful, printable sheet music charts for your music stand, rehearsals, or students. ================================== 100% PRIVATE & OFFLINE ================================== Unlike cloud-based separators that charge per song and upload your audio to external servers, Drummer Notes runs completely on Apple Silicon using Apple's Neural Engine. • Zero data leaves your device — your music stays your music. • Practice anywhere — works on airplanes, in soundproof rehearsal studios, and offline stages. • Fast processing with zero server queues. ================================== DRUMMER NOTES PRO (OPTIONAL UPGRADE) ================================== Get started for free with full access to transcribing your first 3 songs, complete practice mode, and all difficulty levels.

ScouterSynth is a music tracker built like a handheld console. Eight tracks, a D-pad, two buttons, and no menus — every operation is a chord you can play with your thumbs. WRITE Phrases of sixteen rows, chains of phrases, and a song made of chains. Write a bassline once and place it four times with different transposes; change it later and every one of those places changes with it. Phrases can be shorter than sixteen rows, so six-eight is as easy as four-four. SOUND A synth voice per track — saw, pulse with PWM, triangle and sine, through a resonant filter and an envelope — or a sample, played whole or sliced. Wavetables for the sounds a plain oscillator cannot make. Per-tick tables for automation that runs faster than a row. SAMPLE Import from anywhere on your phone, or record straight into a slot from the microphone. MP3, AAC, M4A, AIFF and WAV are all converted on the way in. Whatever you choose is copied into your project, so a saved song carries its audio with it. MIX Ten lanes on one screen — eight tracks and two send buses — with level, pan, mute and solo, and three effect slots on each: filter, bitcrush and a tempo-synced delay. Watch the desk as a set of numbers or as ten live traces. PLAY A performance pad wires any two parameters to an X and a Y axis and moves every track at once. A grid of twelve pads holds six punch-in effects — an octave down, tape slow, a stutter, a bitcrush, a high pass and a low pass — held rather than latched, so nothing can be left on by accident, and six one-shot samples to fire over the top. SEE A radar sweep that reads the mix by frequency, a scope on the output, and six palettes to put it all in. INTEGRATE MIDI in and out with clock. A Bluetooth game controller, mapped button by button to whatever pad you own. Export the whole arrangement to a WAV. Songs, samples and exports all sit in the Files app where you can reach them. No accounts. No subscriptions. No network. The manual is inside the app — press SELECT and B on any screen.
