A Sibelius plugin to convert Sibelius scores to Humdrum

Work in progress

Version 0.14.2

• Consolidated loops in HEADER OF KERN FILE section
• Fixed small typo in gracenote code

Version 0.14.1

• Cleaned formatting of if statements

Version 0.14

• Initial support for grace notes. Slurs and ties for grace notes are not supported at the moment.

Version 0.13

• Initial support for slurs
• Reopened #3 (comment)

Version 0.12

• Clean exit if no active score or active score with 0 staff

Version 0.11

• Hidden rests are now encoded using yy

Version 0.10.1

• Fixes #3 (comment)
• Fixes a bug with start repeat token

Version 0.10

• Ties are supported, but assumes at tie is resolved in same staff/same voice
• Added a TrimTabsLeading method, which simplifies the code and fixes some issues where tabs were either an extra tab was present between spines, or a tab car was missing
• humNewTimeSignatureLine and humNewMeterLine didn't take voices into consideration. Fixed.

Version 0.09

• Keeps track of clef changes throughout the score
• Fixed an issue with the code that keeps track of new key signatures

Version 0.08

• Tuplets are now supported, including the use of extended **recip representation when needed. (I think this works, but more QA on this would be great, as math is not my forte)

Version 0.07

• Supports multiple voices
• Progress bar added

Version 0.06

• Articulations and fermatas are now supported
• Minor modifications to ConvertPitch method

Version 0.05

• Spines are now in the correct (i.e. reverse from Sibelius) order
• Fixed an issue with Whole-Measure Rests. Still uses "rr" though.

Version 0.04

• Dictionaries for pitches and accidentals. Supports up-to double flats/sharps. Other type of accidentals (e.g. quarter tones) not supported.
• Following C.Sapp's changes to Instrument Code, *Iud => *Ioud

Version 0.03

• Dictionaries for durations (tuplets are ignored for now), supports Whole-Measure Rests, but with generic "rr", not the more elegant x%yr version.
• All pitches are assigned to C right now, for QA'ing in Verovio
• Chords are taken into considerations, but not voices (assume always voice 1 for now).
• Fixes an issue with retrieving NoteRests that was present in past version.

Version 0.02

• Keeps tracks of new key signatures and new time signatures (but assumes all staves have same key and same time signature)

Version 0.01

• Generates a legal Humdrum file.
• Retrieves Score info and correctly converts to Humdrum format
• Dictionaries for clefs, key signatures, time signatures (including c and c| time)
• Dictionnary for ~ half the possible instruments in Sibelius. Unmapped instruments appear as *I?? for the moment
• Long and short names of instruments are recorded properly
• Barlines with bar numbers are at correct position
• Basic syntax to evaluate events vs null token is in place (at the moment, events are all marked as X)

---

ToDo

Must Have

• Articulations
• Dynamics + Crescendi
• Pickup bar(s)
• Tempo markings
• Make sure that the file generated doesn't have an extra return carriage character at the end.
• first and second endings

Should Have

• Verify instrument changes througout the Score (currenrtly only initial _ is recorded)
• Support slurs for more complex cases
• Ties and slurs for grace notes
• More instruments supported

Nice to Have

• Add support for multistaff instrument (e.g. piano) *staff2 *staff1
• Beaming (although not urgent; Verovio can do it automatically)
• Create GUI for users to define Custom1Artic, Custom2Artic and Custom3Artic and assign them to undefined signifiers
• Create GUI to decide name of file and where to save (is this feasible? Can't find an example of an existing plugin that lets you do that)
• Piano pedal indications

sib2humplugin's Issues

rr not supported by Humdrum Verovio Viewer

Whole-Measure Rests are currently indicated using the generic "rr" signifier token. However, Humdrum Verovio Viewer doesn't support this, only the more elegant x%yr version (see https://doc.verovio.humdrum.org/humdrum/getting_started/#rests). Using the **recip notation would increase compatibility with Verovio and would help QA.

A workaround for now is to run the Split Bar Rests plugin before running Sib2hum.

Slurs are not rendered if they don't start from a note from the same voice

At the moment, slurs are assumed to start and end in the same staff/voice.

This is not always the case, especially for piano music. For example:

will not generate a slur, because there is no 1st note voice where the slur begins, and thus the slur is never recorded

Deleted rests yield illegal Humdrum file

The code that evaluates the need for spine path indicators works at the bar level, not at the note level. For this reason, deleted rests will yield an illegal Humdrum file. For example, this:

... yields the following humdrum file :

A good workaround for now is to run the Replace Deleted Rests before running the sib2hum plugin.

Don't change the number of new spines by more than +/- 1 per line

Currently, going from, say 6 to 4 spines looks something like this ...

... but this is illegal. Instead, it should be done using multiple lines, like this ...

Voices are not displayed properly on VHV

Right now this:

yields this in VHV:

I believe that iterating from smallest voice number to largest voice number (as opposed to the opposite) will solve this issue. Need to change code accordingly.
