Thanks for the tip, I will add that to the list of compositional work tricks. I am studying videos and material to help with workflow as I dive into this amazing software.

The RealTracks are great and generally play very close to what I have in mind. I have been trying to figure out how to tweak them in certain instances. For example, I have a song I am writing where the bass occasionally plays the root one octave too high. I suppose I can rearrange the audio once rendered or maybe I will explore the MIDI SuperTracks for more flexibility. Any tips or suggestions on streamlining the tweaking of notes and passages in RealTracks for a bass part, or any instrument for that matter?

For the bass part I plan on trying the following:

1. Capture several takes and splice and edit rendered audio using DAW or suggested tool.
2. Use a Midi SuperTrack in conjunction with RealTrack and superimpose accordingly.
3. Try the soloist for some variety particularly on leading notes etc. and then superimpose accordingly.
