Hi Keith,

On the iTouch there is a menu item setting which will Mute a RealTrack.
This sometimes works (as you have found out) but you have to regenerate the song again for it to take.
NOTE: this is regenerate on the Itouch.

What I tend to do (because I play guitar) is in Band-In-A-Box, I mute the Tracks I don't want then save to the BB2go folder. Then load the song back into the iTouch App.

I have noticed what you say about it having been fixed in Band-In-A-Box version 314 but it still has a bit to go.
If you click on the iTouch screen to change the key (say from G to A) it will allow you to do that but that is all.
It doesn't ask you if you want to transpose etc..
So even although the iTouch App is brilliant, I would like to see (over time) the programmers enhance it a little.

For the present I would do most of your work in Band-In-A-Box before sending it to the iTouch.

Just a tip for you....
If you have a midi file that you have opened in Band-In-A-Box and it is all on the melody track.
Move it all to the Soloist track.. then delete the channels you don't want to hear.
If you just mute them by clicking on the play radio button beside the track it will mute the track whilst it is playing but when you generate the song for the iTouch it will play them again.
Phew.......

Best regards
Michee

P.S. the reason you move it to the Soloist track is that the generate as mp4 doesn't look at the Melody track at times...
