<< Most of these have to to with audio, not specifically working with PGmusic content.... >>

That's correct. RealBand can be thought of as primarily to deal with additional live or pre-recorded audio to create, manipulate, audition, and correlate them with the main BIAB program. It completes the package of BIAB software being comparable to stand alone, digital, multi track recorders.

While the introduction of Utility Tracks in BIAB have lessened the necessity of these features, for older versions from prior to BIAB having Utility Tracks and even the versions with Utility Tracks, these functions and features have the same value in a production project as much as ever.

Mixing user-produced audio with BIAB generated tracks has been an important component of BIAB since its inception. RealBand facilitates the interaction between external audio and BIAB generated audio.

<< * can record Mixer automation in real time. - Assuming automation of nodes with external controller (for audio AND RTs?). >>

No. It records most mixer events made with the mouse during a playback mix. Fader movements, aux send movements, panning, master fader and panning moves and group events. It's track specific and works regardless the content type on the track. It works with audio, RealTracks and Midi. I've never attempted to use a controller with the program.

<< * makes it easy to create a UserTrack. >>

You're right. It optimizes the process in some ways.

<< This is a good one too:
"has 3 ways to display time: either bars/beats, time or frames passage." >>

I agree. It also has a convenient large clock display.

<< This I don't get: "has scraps feature (ability to select, load and save regions of audio)"
Well I kind of do... I assume this is mainly for audio, not RTs. >>

No. This feature also works with midi, audio and RealTracks. It's a RB convenience feature that's sort of a copy/paste-import/export-save as combination.
