Hi Aubrey,
Firstly, please be aware that I'm not PG Music staff and that I'm only answering these from my experience.
1) Will these bonus Realtracks come pre-installed on my new hard drive along with the rest of the Audiophile realtracks or do I have to download them? I am pretty sure that I should have got some bonus realtracks with the 2015 upgrade last year but looking now they are not on the Audiophile drive so I guess that I should have downloaded them?
Whenever I've bought USB drive versions of BIAB, Bonus Paks have always been extra and not included. This makes sense to me given that they are a separate purchase.
2) Also what happens to the realtracks from the 49 PAKs of prior BIAB versions when a new version of BIAB gets released? Do they get rolled into the base set of Realtracks for that new release or are they permanently separated from the core product? (meaning that nobody can ever get access to purchase them again as each bonus track set is only ever offered during the special offer launch period for a new release - this would seem to be a waste).
Often, resources that come on Bonus Paks are a once-off purchase and not available again (in the immediate future at least). This would sometimes seem to be due to the fact that the material is sold with limited copyright. For example, a musician who created a particular Realtrack or Supermidi track only gave permission for it to be used in the limited scope of the Bonus Pak.
It is because of the above that I
ALWAYS install new versions of BIAB over the top of existing versions. I then make a backup of my new \bb and \Realband folders onto a USB drive. This way I get to keep all bonus material I've bought and I can get it back if my computer crashes.
3) Finally do I just install the bonus realtracks into the main BIAB realtracks directory? I tend to wipe this main realtracks directory and reinstall it with each new version that I buy but if it contains Bonus Realtracks that won't be re-delivered again then I will have to rethink this strategy (maybe keep a separate directory with a copy of all the Bonus Realtracks and recopy that in to the main directory each release?).
See above... I always install over the top of existing installations. I've been doing this since 2006.
Hope this helps,
Noel
