I thought it was pretty clear in regards to the original question.
OmniPak will not really increase your Styles/Reatracks/Realdrums .. but it will give you other bells and whistles
Audiophile gives you the Ultrapak in higher definition though not more Styles/Reatracks/Realdrums .. just higher bitrates
My suggestion; start with the Ultrapak, if you think you here sound quality issues upgrade to Audiophile
Omnipak seems to include 'everything' (including lessons etc) which is not why I'd buy the program nor pertinent to the original question.
Just want it to make jazz backing tracks that don't sound too robotic and maybe record with it
Does the omnipak have more jazz stuff on it the descriptions are kinda vague and fluff
I don't think OmniPak has 'more jazz stuff' (at least for generating in BiaB).
I used to get the 'EverythingPak' back when it was available, which seems close to the 'OmniPak' .. and it included a lot of stuff I checked out, but didn't need personally.
Stuff like piano lessons, and some kind of ear training game, etc .. not really related to the core use of BiaB, but could be valuable to some.
Like I said. I'd start low and upgrade as the need arises,
but do start with the package (UltraPak) with all the Realtraks/Styles and such.. It'll save $$ down the road.
If you feel the need to upgrade for sound quality later it is pretty affordable. Maybe even beneficial.
Cheaper than adding Styles/Realtracks individually for sure if you get a lesser Pak. Get them all initially in your first package and upgrade as needed.
