Bruce,

Yes, I can successfully drag tracks into Garageband and make audio files that way, but it takes about 5 to 10 times as long, so I'd really like to get the audio rendering working. I have a lot of files to make so I can put them on my iPad to work with iGigbook. I play standards on classical guitar, so I'm wanting to get my set lists with matching upright bass and drum tracks so I can do a Charlie Byrd type trio sound with real tracks backing for my solo performances. I just got off the line (live chat) with Chase who confirmed that the support team will help me with this. Apparently there are settings within the audio driver that have to be tweaked (or something). I had emailed support a couple of days ago and never got a reply. When Chase checked it seems that email never arrived. Go figure. Maybe they've blocked the host of my domain as spam or something. Anyway, they got the email I sent from work (where I am now) and promised a quick reply. I hope they will deliver as promised. What I don't understand is if this is a common issue (or an issue at all, which your similar experience seems to indicate) why haven't they published an article about it in their knowledge base? I couldn't find anything about this searching either the help files, the knowledge base, or this forum, which is why I started my own thread. If they solve the problem I will post the solution here. Cheers.
