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 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 playback. • 16th-Note Grid Quantization: Snap complex syncopations to a clean rhythmic grid whenever you need strict timing reference. • Automatic BPM Detection: Accurate tempo analysis with one-tap half-time (÷2) and double-time (×2) overrides. ================================== 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. • Zero data leaves your device — your music stays your music. • Practice anywhere — works on airplanes, in soundproof rehearsal studios, and offline stages. • Instant processing with zero server queues. ================================== DRUMMER NOTES PRO (OPTIONAL UPGRADE) ================================== Get started free with full access to transcribing your first 3 songs, complete practice mode, and all difficulty levels.
