cubase 10

I’m running windows 7 , cubase 10, and a third party plugin drumagog . i can open an empty project and run drumagog and it works great. when i open a project that I’m working on with mate 20 tracks i can see drumagog but it don’t open. is there something I’m doing wrong, or maybe two many vst instruments ? any one have this issue or no what i can do to fix it. like i said drumagog works fine in empty project . thanks for any info…

Maybe you hit the FLS limit. A thing that’s been discussed for a while (https://www.steinberg.net/forums/viewtopic.php?f=283&t=147179) and will get solved with the next big Windows update.

The symptoms at least sound like that could be the issue. Try this wonderful tool meanwhile: https://planetnine.jp/wp/2018/03/25/fls-checker/ and see what you get.
