I was using it for a while, promoted it way back and it served a purpose but was a little too error prone. The idea behind it is what the plugin now uses, a biab app that runs silently in the background generating up the tracks (this side is very solid) to a folder that are then played back in sync to the DAW or dragged in. I'm just using the plugin in Reaper now with ReaTrak that imports the chords from the plugin into Reaper, you can also generate up the RealDrum track directly in Reaper that gives you a bit more control, it will let you fit tracks from the plugin to a tempo map so it will fit RealTracks/Drums to a live session.
Just looking also to create a script to get the chords from the plugin into Cubase.
They might be adding midi import to the plugin to get the tempo map/time signatures from the DAW into the plugin or vice versa and be able to export the chords from the plugin via midi file markers.
