You'd have to disable RealDrums so that MIDI drums are generated, disable the DXi synthesizer, and select a MIDI Interface as your MIDI Output Driver, which would need to be connected to the HR-16. You'll also want to make sure you're using RealTracks for every instrument except drums.

You may also need to change some settings to the HR-16 so it plays from a MIDI input instead of using its built-in patterns.

I doubt it'll end up sounding as good as the RealDrums, but it should work. smile
