Re: no midi to Spectrasonics...
Well, according to the Spectrasonics website you do need the latest versions of their instruments for Monterey [and the new M1] -- you didn't mention any specifics [what instrument, what software versions, etc], but I assume when you reinstalled it was the most recent Spectrasonics versions..?
You've probably tried these already, but just in case here are a few standard troubleshooting steps that might apply..
- Do a hard shutdown/restart [if you haven't already].
- I assume audio is working with other instruments [the issue is specific to Spectrasonics], but if you haven't checked yet..
- Maybe check the UA Console utility to see if any settings there have changed..?
- Check any Spectrasonics preferences/settings -- again, maybe the reinstall might have changed some settings..
Here's a Spectrasonics help page on troubleshooting No Sound From Instruments:
It talks about what to do if you do or don't hear audio from the Preview button vs triggered by MIDI, so maybe that could be relevant..?
