Using Scalar2 with Reaper?

A friend showed me the Scaler2 plug-in. It looks awesome and a great tool for composing ideas!! And at $29, its hard to pass up.

Has anyone used it with Reaper?? Most YT tutorials show it with Ableton, Cubase, etc. Reaper is on the "compatibility" list for Scaler so it will work. But I was wondering if there are tricks/tips for using it effectively with Reaper.

Thanks!!!
