Joe: I have no idea what that means.

All: I am a newbe to recording, pro audio, and band in a box. Do do understand music, chrods, etc.

Without rehashing the above... I am someone who looked all over the website at real track demos, styles, and more. I realized I could create practice tracks for my kids fiddle studies. My oldest 2 kids take lessons. My 7 1/2 year old has 30- 40 tunes and plays in OTF contests. Dad can't strum with her every night for long periods, and has to be out of town as a traveling salesman every week for a couple of days.

I wanted the sounds I heard in the bluegrass related real tracks.
I was confused by the number of packages offered.
I called PG sales 3 times and spoke to a female sales rep.
I called Janet Davis music multiple times because they are a dealer and specialize in bluegrass related stuff.
Both parties were polite.
It was still unclear if the "bluegrass pack" being offered would do what I needed or not, but I was told it had realistic enough sounds for performance backing tracks.
This was not the case.
I should have purchased the ultra plus or everything pack,

Yesterday I called PG tech support and got some questions answered. I also upgraded to Ultra plus package. Since downloading certain real tracks, I am on my way.

I still have some questions, but will try and put those in the appropriate places.

Thanks for your time and effort to help.
