All kinds of note errors, rhythm errors and dynamic errors have been handled, but some phrasing errors are still missing: version 1.0 of package VMT does not handle legato/staccato errors.
We have already introduced the legato parameter in the score text file syntax and the internal model; that means we are able to know when a legato or a staccato is expected. The problem is how to detect such an error, that can be explicitely in conflict with rhythm error detection (note too long, note too short).
Handle such phrasing errors will mean find another way to detect rhythm errors, or at least find a way to preserve real-time signalisation for errors that are during more than one note and that can be in conflict with other error types.
