Hi Owen!
Thanks for reaching out to us!
I’m not really familiar with the Memberships Pro plugin. I know some users use it alongside with our plugins.
The events are a custom post type, so as long as Memberships Pro plugin allows the attribution of custom post types to membership levels, it should work find.
Let me note that we work hard to make our plugins broadly compatible. However, like all WordPress developers we cannot test with every plugin, theme, and server environment out there. So, we suggest you test this integration in a dev/staging environment to make sure it works as expected before implementing on your live site.
I hope that helps. Let me know if you have other questions.
Best,
Victor
