Instra-Swap
The music is written for the wrong instrument.
Instra-Swap rewrites any part for whoever actually showed up to rehearsal. Transposition, clef, octave, voicing and tabs — instant, not by ear.
Instra-Swap engine
Paste notes, snap-scan results or pick a demo line. Notes are written as letter + octave (C4, Eb5), with an optional length (/w whole, /h half, /q quarter, /e eighth, /s sixteenth, add . for dotted). Rests are r/q.
Eb Alto Sax: Eb — up a major 6th · treble clef · range G#3–F6

Note-by-note view
Dual-input transcription
Snap a photo of printed music or drop an MP3. Optical music recognition and stem-separated audio-to-MIDI turn both into editable notation.
Deterministic swap math
Every standard transposing instrument's interval, clef and written range is built in — so a Bb trumpet part is right the first time.
Playable, printable parts
Range warnings in red, one-tap octave fixes, guitar and bass tab, and clean MusicXML/MIDI exports for your DAW.
