Yes.
I unplugged, plugged back, restarted Dorico, and keyboard several times and combinations of all this and for noq it’s working again. Not sure which of my actions fixed it for now but the issue seems to come back when some conditions met - like being idle for example.
How do I start the HALion standalone app without launching Dorico?
It’s a standalone application, in your /Applications folder.
Yes, all the notes are playing together no problem
But I suspect that the notes are sounding together in Dorico in any case, because the dead-time interval is set to 100ms, which to the ear means the notes will sound pretty much together, but Dorico may yet consider them to be successive notes.
If you are feeling brave, you can go to ~/Library/Application Support/Steinberg/Dorico 5 in the Finder and open preferences.xml in a text editor. Use the find function to look for stepTimeChordDeadTimeMs and you will see a value of 100. Try changing this to, say, 200, then save the file.
Make sure Dorico is not running when you make this change, otherwise your change will be overridden next time Dorico writes its preferences.
You can change all three of those values to 200 if you wish, but the one that is used for step-time note input is (as its name suggests) stepTimeChordDeadTimeMs.
OK, I changed it, and so far it works. Now I am able to enter the chords even with the bluetooth connection. I will monitor it and let you know. Thank you much!
Also, why do I have this issue that requires me to go into the coding and change the values there? Is it a bug, perhaps?
No, not a bug, since as you can see we have to some extent anticipated that this may need to be varied between systems, though it is needed sufficiently rarely that we do not actually expose this option directly in the user interface (in general, if we can avoid having an option for something, we will).
The issue is with your keyboard, I am certain, given that every Dorico user has the same default value, and this kind of issue is exceedingly rare.
Nevertheless, now you have a setting that works for you, hopefully that will be the end of it.
