FF: Try the Condutor window...
Ummmm, no. I did quite a lot of that several years ago when I worked with a sax player and occasionally him and a singer. The saxman also fronted us and likes to talk and extend parts of tunes. The problem with the Conductor is you still need some warning that the vocalist or leader has decided to extend a verse or stops singing to talk to someone and I was expected to vamp. It was a near disaster several times. In the heat of battle neither one of them could give me any warning. They're used to bands and they just signal a vamp or take the bridge or whatever.
I finally had to get the guys to swear they would follow the song rather than try to lead it like they normally would. They kinda sorta did it but were not happy about it. They couldn't be themselves any more and it is a legitimate part of performing. It wasn't the sound quality, they loved that, it was the lack of control.
After a few gigs like that I broke out my Korg Pa1XPro arranger keyboard for the reasons mentioned earlier. I have total control that way even if the Korg's styles are not as good as Biab's. It does sound great though and if I had more time I could have created better song specific styles for it.
Playing Biab live on stage is fine as long as you're the leader, singer, whatever and if you have a partner they follow you. Then the Conductor can work.
