Yesterday i looked at the user track templates and see there is a 30 minute one. I assuming that is continuos playing on the part of the maker. My question is can one make a track in parts and paste it together in audacity or elsewhere? Having only one lung now, I simply can't play that long but I can for a minute or so. Or perhaps I have mistaken the various charts for continous play.
sorry if this has been asked before--a link will help in that case.

Yes make them how you like, any way will work. If you have BBWin you can use RealBand paste the sections together or record a section at a time by stopping then start recording on another track just before the previous recording.
You can also save the usertrack template to video so you have the chord sheet, load it in a DAW and record one section at a time by dropping in as above. Reaper is good for that as it's free to try n try until your heart's content.

As Pipeline said, yes you can make a big UserTracks from small parts. All you have to do is make matching audio and SGU song files.

The name of a UserTrack is the folder name. Inside the UserTrack are audio and SGU file pairs. Each file pair can be of any length between 1 bar and 255 bars. Just remember that the audio file of each file pair must start with two bars of silence so the program, BiaB or RealBand, can play the two bar count-in so a one bar audio file will actually be 3 bars in length (2 bar silence + 1 bar silence).

The file pairs inside a UserTracks folder can be named ANYTHING you want, as long as the audio file and SGU file share the exact same prefix.

For instance name a folder "My UserTrack" (without the quotes) then place the folder inside the x:/bb/Realtracks/UserTracks folder and "My UserTrack" will show up as a UserTracks the next time you access UserTracks.

Inside "My UserTrack" you can have as many file pairs as you want. BiaB and RealBand will "see" them as one UserTrack. Each file pair will look similar to "A.wav" "A.SGU" "B.wav" "B.SGU" "C.wav" "C.SGU" (once again without the quotes) and so on.

Band-in-a-Box and RealBand uses each SGU file to know what is contained in each matching audio file so it is important that your recorded playing matches the chord chart.

so then the FINAL wav or wma file MUST be 30 minutes long for the 30 minute template, not just a series of 10 minute wav files. Is that correct?
thanks Jim and Pipeline for the previous answers and link.

I look at the 30min template, there are 27 SGUs they are all about 1:10mins of playing @ 120bpm.
So if you can play for a minute at a time you won't have any problems.
For every SGU you will have a wav file with the same name.

The two most important things in this context is to make sure that

1. The name of each of your UT .sgu file is identical to the corresponding .wav file.
2. The tempo of each of your .wav file is identical to the set tempo in the corresponding .sgu file.

The precise time length of the end result is basically irrelevant, if not but because it varies considerably depending of the tempo of each Usertrack. A 60bpm song file with 30 bars is thus obviously going to run longer time wise than a 180bpm song file with 30 bars, simply because it's slower.
