Hi friends,
first of all, congratulations for the work you are doing. I’ve always waited for this. Everything works great with version 1.8.1 (Natalie) The new beta 
(Natalie 2nd version) crashes as soon as you use the piano roll. Also when moving notes it can happen occasionally when working with a second track I’m working with Studio One, latest software on MacBook Pro M1Max/64Gb/Monterey. Many greetings from Kisdorf/Germany, Kalle Koerner
