I hope everybody is aware that midi creation/generating plugins are at the moment incompatible with the current version of Studio One. Scaler runs in demo mode, EZKeys gets stuck in the project and can't be completely deleted (ghost notes and sounds keep popping up after you remove the instrument), and Playbeat and other Audiomodern plugins act weird (do not respond if you click on something, etc). These are just a few that I have tested. I suspected that this was a S1 issue and not the plugins themselves, but just to make sure I tested them all in Cubase and they worked fine there. I opened a ticked with Presonus and they replied quickly to let me know that they were aware of the issue with Scaler (that was the only one I had tested a few days ago when I wrote to them). I hope they can fix this soon because these are plugins that many of us who unfortunately aren't towering virtuosos can not live without.
