< Is it possible to record the audio output of a track to another track within BiaB? >
Yes it is

<< I want to render its audio output to another track. >>
This is possible. Assuming you're playing the sequencer live and want the audio to print to another track

<<< I have something being generated off a MIDI chord track, and I want to bounce that audio on to a separate track? >>>
Yes, this is possible.

All three of the scenarios you describe can be done solely within BIAB. There are multiple methods. Two common ways are:.
1. Use a virtual cable
2. I have the RealTek sound card and it has the 'record what you hear' feature. Use Mute to silence everything but what you want to record from the Mixer.

Using either of these will do these task you listed. I tested this morning with rendering output from one track to another with audio, Midi super track, and Midi. No issues with any format.
