Thanks, but once I'm in Reaper, there are a zillion much simpler ways I can accomplish this anyway (and so much more, which is why I'm so eager to use the plugin in Reaper rather than working in the main program. I tried using the plugin again today, and when I tried hit generate to send the audio and MIDI to Reaper for under a dozen tracks, it started generating dozens and dozens of empty MIDI items or something and promptly crashed my project).
