Nice! Questions... Do you import the midi from Hydrogen, or have it synced up in some way, or do you record the audio output into Reaper? When you use ToneLib, are you using the standalone, and piping it back in, or are you using the plugin? And are you doing stereo tracks coming out of ToneLib? Or did you explain this somewhere on the Ardour listserv? From someone who is doing things eerily similar. And yes, I see this is over 2 years old.
