Hi Charlie, Thanks for your help.
I hit a snag in your instructions (shown in red) but I think I figured out what you mean. It still does not work. Maybe you can spot the issue from my steps below.
--I am running BIAB 2018.
--I have 4 choruses of 32 bars each chorus.
--I have melody on all choruses but I mute it just before chorus #2 (in bar 32) and reset it in bar 32 of chorus #3 so it will play the lead in melody note into chorus #4.
--I generated a solo using the (Soloist, Soloist - generate and play a solo... Shift F4, clicked "Best Real Tracks", chose a real synth, and I had "mute melody in middle" checked then I pressed okay).
--So that works for the middle choruses (#2 and #3).
--So to get to your suggested popup I right click on Bar #1 and choose Bar settings.
--I click on the "All Choruses" button and choose Chorus #3.
--
I do not see any "Bar #" box in top right of this dialog window so I assume Because I have right clicked on Bar #1 I have essentially done the same thing.--I click on the "Real Tracks" button as you suggest and I choose the soloist track.
--I then go down a bit and click the drop down and a new dialog window appears.
--I search for "solo" and get a revised list of tracks.
--I choose 434 Fiddle, Soloist Bluegrass Ev 130 and click okay.
--I show that dialog box in a picture below.
--I Then click okay to the next dialog box down and I am back on the Bar settings.
--I show a picture of the bar settings at this point.
--So I close down the bar settings dialog window.
--I then do a regenerate and play song (F4) to try and get it to pick up the change.
--The result is I still get the synth soloist playing on Chorus #3.
Can you see what I might have missed?
