rharv is correct. I use both ez drummer and SD2.0 - I cannot get ez to work with RealBand. You cannot audition the midi groove before you drag and drop. Full VST support has been on the wishlist for PG to address for about 5 years now (and counting)but this has not been forthcoming. Jamstix and a few other plugins are also problematic in RealBand.

What you can do is save all tracks to individual files and import them into another DAW. You can then use any VST plugin that requires some form of tempo clock sync. Unfortunately even though RealBand is a great package it still has some shortcomings generally found a standard features in other DAWS.
