I have searched the forum but cant find the exact answer to this so sorry if its been asked before

I use BinaB Ultrapakplus 2010.5 to create backing tracks for both myself on Tenor Sax and sometimes a small group--Tenor, Soprano, Clarinet, Trumpet--all Bb.

I use Fake Books to get the melody lines and chords--I always buy the version for Bb--Just got the Hal Leonard 600+ Jazz Standards

The thing is that I always assumed that the chords shown in these books are in Concert so that say a piano can play the chords as written as backing for Bb instruments

That being the case I leave the key sig in BinaB at C and then enter the chords--It doesnt work--I have to get BinaB to transpose the chord sheet to Bb to get everything in tune--the thing is though that we then seem to get a odd chord sequence on the screen to solo over--musical experts we are NOT so it might just be us--but why call it a Bb Fake Book if the chords are not correct for Bb instruments in the 1st place

My question is this

If I set the key symbol to Bb in BinaB before entering the chords does BinaB actually play them in C but we get the right chord sequence to solo over on the screen

As an aside can we set a soloist to only play in certain bars in ceratin choruses to give us the option to put a piano or guitar solo in our songs
