Just to echo musicplay’s and Timothy’s experiences, I’m having significant problems with the pitch bend controller, as well.
Changing the rhythmic grid is definitely an issue. If I start plotting pitch bend values on the timeline, and then figure that I need to refine the shape of my curve, I increase the resolution of the grid – then promptly lose whatever edits I had made.
Also, preexisting values on the pitch bend timeline will be suddenly misrepresented; they’ll play back fine, but a value that was, say, 17 previously will now show as 1 in the interface. It definitely happens after I change the resolution of the rhythmic grid, but even just zooming the view in Play Mode has produced this effect. Stuff like that.
After a particular bend in my score, which was set back to zero as usual after the note played, I heard an odd decaying effect in which successive notes gradually pitched downward, as though the whole melody were “melting.” In an attempt to pinpoint the cause, I erased the relevant control points from the timeline – whereupon the pitch bend played anyway. Another instance of the values on the graph (nonexistent, in this case) clearly not representing what would be played back. (I’ve posted to my personal web site a video that demonstrates this particular bug. Despite edits to the pitch bend controller, including massively changing values and even deleting them, playback remains the same.)
As the title of this thread indicates, I’ve had Dorico 3 crash on me a few times when entering or moving (I can’t recall which, precisely) pitch bend values, too. Fortunately, I haven’t lost a significant amount of work when this has happened; I’m in Paranoid Mode, now, so I’m constantly saving after even just a few modest changes to my score. Plus Dorico seems to be good about recovering work after a crash, so thumbs-up, there.
