--- Comment #3 from Gary Wilks gazblin@gmail.com --- (In reply to Andrew Nguyen from comment #1)
Wine 9.0 is an outdated version. Please retry with a newer version (stable 10.0/devel 10.16). Is there a freely available download for the MidiWorks GM application?
Thank you, Andrew, I will look for v10 of Wine - and hope it does the trick. And yes, the are freely downloadable demo versions, only from MidiSoft site. I use both the fully-paid-for MidiWorks GM and, occasionally, MidiWorks YA programmes
I'll keep you updated
Best regards
