Anybody else had this, when I have a VST open and the on-screen piano keys, some VST's don't play (using your actual computer keyboard) till you close the VST window.
Happened again yesterday when I purchased U-He Repro-1 and Repro 5, happens with both and also happens with the Korg M1. Doesn't happen though with Air Music Technology Loom so it isn't happening with every VST.
I just thought I'd put this out there before I contact Propellerhead. I've already contacted them about 5 weeks ago about this issue with Korg M1 but wanted to contact them as it's quite annoying and obviously an issue.
