Using Sibelius, I have across both types of corruption which were explained to me, in the following way:
file corruption, where the file won’t open at all
rhythmic corruption- The file will open and play properly, but there are rhythmic errors, and when trying to copy/paste stuff, some of it it disappears.It is most usually caused when the notes/rests are input either by importing a file (either MIDI or MusicXML) or by Flexi-time option with extremely sensitive settings chosen, or more rarely,where the music is created through conventional mouse/keyboard input, and sufficiently rhythmically complex that you’re operating at the edges of what is supported by Sib, if not beyond.
I still do have this problem which is also attributed to doing a lot of editing, and Ive even come across stuff which copies and pastes back the same way, and is still visibly incorrect, but audibly correct on playback. I enter music thru conventional mouse/keyboard input.
Is it possible this kind of problem might also show up in Dorico–ie mainly that youd be able to hit its ‘complexity limit’ and errors will then appear, in the form of rhythmic corruption?
Thanks so much–and looking very forward to using Dorico!
