I’ve been looking into this, and it transpires that grace notes are, at present, intentionally ignored when it comes to playback techniques because some additional handling is required that needs further implementation.
@dspreadbury it’s been a year since this last message, and I was really hoping this would make it in for 5.1. Any chance this is on the radar, or should I expect to need to work around it for the long term?
I can’t say for sure when it will be addressed. As I indicated to you in my previous reply, it’s quite involved, and it’s not a simple thing to implement.
