Yesterday I loaded a registration that I prepared on a Tyros3 into Genos. I didn't expect it to work but I wanted to check if there was possibly used a preset style. After pressing the Reg1 I continued to work with the Chord Looper. To my surprise the Chord Looper didn't work, I could record chord sequences but it was impossible to loop them. Good news is that rebooting Genos cured the problem. It might be a dumb idea to open a prehistoric registration, but doing so should not compromise the Genos operating system, IMHO.
Anyway, lesson learned...
