It appears to me that the midi super tracks could have been constructed at the real tracks sessions.

I have no idea what PG Music has actually done in their recording sessions. There are high quality hybrid pianos which produce both analog sound and midi information. There also exist high quality pianos that produce high quality digital sound and midi information. I own a digital piano that when I play it into my DAW the analog output goes into the A to D converter and and on to a track. The midi information is transmitted at the same time to another track.

It is also quite common for live acoustic drummers to have midi triggers on their drum kits and to produce both analog sound and electronic sound concurrently. I have gotten so used to hearing electronically produced drum sounds I actually prefer it in most cases. I personally don't like some of the real track drums in BIAB because they are on one track. That makes it extremely time consuming and sometime impossible to have the the level of control I would like.

Due to latency and other technical issues midi guitars have never been very popular. There are woodwind midi devices that also have many technical issues due in large part to the midi 1.0 specification. I have read that the new midi 2.0 specification may go a long way to resolving some of these issues.

The pattern based midi would and does produce a very generic comping arrangement while a performance based midi file would automatically be less generic. Anything can be done with midi to include creating a complete piano track one note at a time. It is fine to fix a few notes or chords you don't like. It is like punching in a few misplayed guitar parts. At some point all that is pointless. It becomes garbage in garbage out, more trouble to fix than to play again.

I find the blue "midi super tracks" to be much better than other midi tracks in BIAB.

My question was to try to understand if I am missing anything.
