Hello,
there was a long standing compatibility issue with Notion and Sampletank 2 on Windows only - this has now been resolved. So you can certainly use Miroslav 2 with Notion 5, as you can any VST instrument. There are no presets included with Notion for Miroslav 2, as there are for Miroslav 1 - but Notion 5 had a new Rules Editor feature, which allows you to create your own custom set.
