| - | * Double slur / phrasing slur [DebuMand] | ||
| - | * Dynamics assigned too late / at wrong position [BeetAnGe] | ||
| - | * Foreign characters in Title [Echigo] | ||

| - | * Hairpins ending in different voice [DebuMand] | ||
| - | * Lyrics on melismata/ | ||
| - | * Make use of the placement=" | ||
| - | * Measure messed up at clef change [BrahWi#5] | ||

| - | * Voice 1/2 messup [Teleman] | ||
| - | * percent repeats | ||
| - | * Add check whether the input file is really a MusicXML file... | ||

| - | * Tied note w/o notated tie curve | ||
| - | |||
| - | ===== Missing features in Lilypond ===== | ||
| - | * StaffGroups can only be nested two levels, then the hierarchy is messed up [08b] | ||
| - | * In Lilypond, staff groups cannot overlap (only be nested), while in MusicXML, overlapping groups are allowed [08g] | ||
| - | * In Lilypond, chords that have some notes on one staff and the remaining notes on another staff of the PianoStaff are not possible [14c] | ||

| - | ===== Notes on erroneous MusicXML files ===== | ||
| - | |||
| - | === Finale 2007's exported files === | ||
| - | |||
| - | While the MusicXML files exported by Finale (or rather the Dolet plugin for finale) should in general be regarded as the reference implementation for MusicXML, some of Finale' | ||
| - | * Single-note tremolo (i.e. slashes through the stem) | ||
| - | * barre elements in fretboards | ||
| - | * multiple fingerings/ | ||
| - | * in fretboards, even strings without any information (neither explicitly open nor muted) are exported as open string (represented by an " | ||
| - | * fretboards assigned to a particular staff in Finale lack the < | ||
| - | * part groups with a square bracket in Finale are exported with the " | ||
| - | |||
| - | === SmartScore Pro === | ||
| - | * Pickup measures are padded to full measures with < | ||
| - | * Mid-measure repeats cause one full measure before the repeat (padded by < | ||
| - | * Titles, Composer, etc. are not detected as such and are put as ordinary < | ||
| - | * Full-measure repeats are not exported to MusicXML, so there is no way to detect really empty measures as opposed to full-measure rests. | ||
| - | |||
| - | |||
| - | === Capella files from Hausmusik.ch === | ||
| - | |||
| - | http:// | ||
| - | * Even single eighth or sixteenth notes get a <beam number=" | ||
| - | * Sometimes beams are not ended, making subsequent flagged notes in lilypond appear with a beam instead of a flag. This happens e.g. in [[http:// | ||
| - | * Clef and key changes are inserted into the MusicXML even when they are not necessary. This happens e.g. in [[http:// | ||
| - | * Some notes have the attribute print-object=" | ||
