BIAB uses its own soundfiles to create the backings, so an better internal soundcard or an external one, are unnecessary, unless you intend to play the backings direct from the computer, and even then the internal sound chip should be more than adequate.
Even in its basic stage BIAB can generate pretty good backings, it's the users who make it sound good or bad depending on their expertise and ability to RTFM..
Playing live from the programme is NOT the WTG. You generate the backings and convert them to whatever format your playback system uses, usually mp3.
There's a plethora of mp3 apps that allow you to set up a playlist in seconds..for Smartphone or iPad usage.
There are tutorial videos included even with the basic BIAB that explain all.
My advice is to watch every bit of them, and then try out what you've learned. Trying to make your own backings straight away is the temptation most succumb to, consequently NOT learning enough about the nitty gritty.. If you have ANY questions about its usage when you get it, just ask me.. 24/7 text and voice from 08:00 -02:00am any day 07800-646-645
Finally, it's NOT rocket science, just a case of memory intuition and the ability to assimilate instructions. Of course some knowledge of chords is an advantage, but even that can be circumvented by getting the info off the net and typing in the chords you've found..NOT the best way.
If you ever want the chords to ANY tune, just send me the song/tune as an mp3 or a link to a video etc and I'll send you the chords back in BIAB format ready for the programme to play and you select the key-tempo and sounds.. etc.
You can e-mail my 'phone that's always with me.
[email protected] or PM me on Facebook, both of which I get instantly as well as text of course.
I won't advise on what computer to get because almost any one nowadays will be fine. What I can advise is that if you get a laptop, get a mouse, It's a far more practical way of using the program. BUT looking at this post again, what is the computer you're using right now to access the 'net' ? it's probably more than good enough to host BIAB and serve as the main base for your programming..
