Dear Mr Norton,
I've been using BIAB off and on since 2012 or so. My latest version is 2020 (Windows). I've opened very many style demo files (SGUs) which come with BIAB, and every one I've tried has always let me change the entire band style, or individual instruments, from whatever they were set to, to a completely new style or instrument, whether it was a midi style or a Real Track.
<...snip...>
If others experience the same problem with this file, I'd suggest you perhaps make it clear on your site whether one can in fact expect these to work in the way other SGU files do - i.e. again, you should be able to play any track thought any RT if the chords are already entered. I'd also ask you to consider refunding my purchase, please.
As far as I know, nobody else has this same problem.
1) I made this song in BiaB and saved it, just as anyone would have done. Nothing fancy. So they do have basic sgu functionality.
2) I tried it on my computer, and it switches to RTs perfectly
3) Other people have used this same file and switched to Real Tracks.
4) I answer all e-mails, and never got one from you (I just checked again - and checked my web-host's spam filter rejects).
Note: If anyone ever e-mails me and doesn't get a response by the next day, or in very rare instances the second day, please try again
5) There are also free samples in the song lists of all my fake e-disks, so you can try before you buy
6) Since it's working for me, and since I've had zero complaints since I published this book decades ago, I offered another, simplified file as a first step in a troubleshooting process. If that passed, I would try a more complicated test, until I figured it out.
7) I've been making fakebook collections since 1991 or 1992, I've made 53 of them, with as many as 700 songs in each collection, and I've never-ever had someone who couldn't switch to a real style. So in troubleshooting it makes sense to me to start with something simpler.
I do have another idea. Try this. Press F5 on the first measure, and clear the style in the dialog box. Then try again.
Let me know if that works for you or not.
If you tried the first bare-bones test file I offered, and it worked perfectly, I would have put a F5 (BiaB dialog box) to replicate the one on your file as the next step. If that didn't work, I have a few more things to try. But you have to cooperate with me as I try different things.
If you prefer to keep this out of the public eye, e-mail me again, and if I don't answer in a day or two at the most, try again.
I answer all e-mails by the next day, the rare exception might be if an emergency occurs, I have an out-of-town gig, or a couple of times a year, I just want to take a day off.
Since 1991, when I started selling BiaB add-ons on 5.25" and 3.5" floppy disks for Pre-Windows IBM DOS5, Atari ST, and Mac System 6, I've had very few problems, and I've never had one that couldn't be fixed. Sometimes it takes a few tests and tries first.
I won't give up until either it's working for you, or it's a PG Music problem. I will not refer it to PG Music unless I'm 99% sure it's not my problem, so bear with me while I go through the troubleshooting process and try different files.
