After entering some chords, I then open the style picker and audition different styles. Then, after several minutes, the program crashes and I have to re-start. It's done it on my 2019 iMac, my 2019 MacBook Pro, and even when running the program off the USB dirve that PG Music supplies. I have emailed PG Music support and provided them with the crash logs, so hopefully, they'll have an answer.
