Actually I‘ve found four bugs.
1. Third Plugins like Waves AU don‘t show up. It gives me a black screen.
2. When I work during a cycle mode the sound is getting louder. When I stop the song and play it again it returns to normal.
3. When I listen through Kickdrum Loop in the browser (contains 4 Kickdrums), it seems that the first Kick contains an extra click.
4. While the song is playing and you toggle the cycle mode on and off I get a noise.
Hope Presonus will fix it very soon :)
