Lead Sheets XML is built for any musician who has ever needed to transpose music in the moment. Load a MusicXML lead sheet, pick your key and clef, and get a clean, readable score in seconds — no desktop software, no reprinting.  WHO IT'S FOR  Singers: transpose any chart to your key and share a clean PDF with your band and accompanist in seconds.  Instrumentalists: adjust the key on the fly to match your singer, or accommodate a last-minute key change without reprinting a thing.  Bb instruments (or any other transposing instrument): always have your music in the right transposition — no more mental math mid-rehearsal.  "Alternate clef" instruments (viola, cello, you know who you are) : switch any treble-clef chart to alto/tenor/bass clef instantly, and adjust the octave to fit your range.  WHAT IT DOES  - Renders MusicXML files directly on your iPhone or iPad — no conversion needed  - Transpose to any key with a tap  - Switch between treble, bass, and alto clef  - Shift octaves up or down  - Set your instrument once — Bb, Eb, F, etc... and transposition is automatic on every file you open  - Export a correctly transposed PDF to share or print  - Works offline — no internet connection required  - Open files from iCloud Drive, Google Drive, Dropbox, or any cloud storage compatible with iOS - Import and save files locally for offline access  - Export to PDF to use with forScore and MobileSheets TESTED BY MUSICIANS - Used by musicians on stage, workshops, and rehearsals.
