In the second screenshot, I converted a midi track to audio in order to confirm the recorded audio was exactly the waveform as the source track. It was, other than seen in the screenshot, amplified a small amount. This is the same to live recording into the Mixer or moving existing recorded media to another track.

Rendering a mix in BIAB is creating a stereo mix of all unmuted tracks in the BIAB Mixer. That being the case, when you state you want to hear everything in context before I render. Simply record normally and if you want to move the live recorded track, you can copy/move or bounce or render.

BIAB is a very robust digital multi track recorder. In multi track recording, a bounce is playing previously recorded tracks by recording a mix of these tracks onto another track or tracks. Live instruments can be added during a bounce as well.

To my understanding, it seems you want to hear everything but only record your live playing. Is that correct?
