Thank you for bringing this up Keni. I will keep an eye on the pan settings. If I am understanding this correctly (I've only scanned the thread) the Room mic bus is using an opposite pan config than the close mics and perhapd even the overheads.
That is annoying and really doesn't make a lot of sense but there are few things XLN have done recently that don't make a lot of sense.
I gotta wander though... this could be a preset specific thing. As in perhaps you have stumbled across some presets that have reversed the perspectives to create a certain effect.
As far as the raw samples and/or using AD2's internal processing... yeah, the raw samples are useable but it's not like with BFD or expansions by Platinum Samples where what you are getting is more like the raw recordings you'd get from a quality mic job in a good room on a nice kit. AD has always seemed to rely more on it's processing than the actual samples. The samples may have been created with this in mind and their presets are very nice.
I look at AD as a "drop it in and forget it" (and maybe some light tweaks either in AD2 or the DAW) type of sampler where BFD is more what you get from actual tracking (more work but a skilled producer can treat it like they would a live session). BFD still has some decent presets and I'm only on Eco so I'm sure the full version(s) have much more going on.
Cheers.
