<<< Is it possible to have a different RealTracks generated soloist for selected bars using the 'Soloist' track?" >>>

I'm tempted to offer a prize to see if anyone will answer the actual question asked. <grin>

It's specific, multiple RealTracks on the 'Soloist' track on the BIAB Mixer.

I agree with Bob Calver
This process inside BiaB is a bunch of convoluted and confusing steps to me (sorry)
Doing the same thing in Realband is a walk in the park.
You bought Realband when you bought BiaB .. no cost to you to try it <grin>

Really? Let's compare.

Use BiaB to get your idea down (figure out chords, tempo, style)
Check
Then open that same file in Realband and expand on the ideas
And ---
Wait for RB to open
Wait for RB to activate
Wait for RB to load the BIAB tracks
Wait for RB to regenerate new tracks you don't necessarily want because here we must mention once you start down the RB path all the BIAB tracks are regenerated and the 'original tracks' don't carry over from BIAB.

First of all you get 48 tracks in Realband, and you can cut/copy/paste/generate any sections of those 48 tracks you want. Basically you have 40 more 'Soloist' tracks to work with.
Not really. You can 'see' 40 more tracks but you can have the same amount tracks to work with BIAB that you use in RB.

You can select the solo section and try a sax, guitar, flute and washboard .. then figure what parts you want from each .. or redo them all again until you get a solo you like .. without affecting any other tracks.

Ditto BIAB

It is so much easier there.

Not really. Actually, the ease of use can be the same in both BIAB and RB but only after you've gone through the unnecessary time to open RB, load the BIAB file, wait for activation and regeneration and lost all of your original BIAB tracks.

In both BIAB and RB, you can open the Stylemaker, filter and select a Style with Medleys, generate and play. Voila, multiple RealTracks Soloists across select bars on the Soloist track. Done. Fast, simple and no convolution.
