I've used battery since Komplete 5 days, and I like it, (and Kontakt),  enough to not buy something else. But I must say, I could use some clear tutoria on the subject. The battery manual and pdf aren't much help to me.
 
Thanks for the advice guys.
 
So I did what was suggested and added a new instance with all the separate output tracks now in Sonar. 
  
But once I've frozen the synth tracks, with the audio waveform visible on the tracks, what's next?
 
I mean, they're quasi-audio tracks, and .wav files have been created in the audio folder so I don't need to render them? But if I mute the source MIDI track, they are all muted.
  
Thanks
