FM, I have BFD open right now, on the one project where I felt I got to my "final settings". This is just one drum set that I created, and is specific to a hybrid funk/ska feel, so take that for what it's worth. But I have found it is a good starting template for some of the other drum sets.
I think I might have set it up from drummer's perspective, as I work with a lot of left-handed drummers anyway and so have no specific reference in my head as to which is "right".

But this is separate from stereo width and how close that puts one to the drummer.
Anyway, here are the mix settings I used for this one drum set, after removing all internal effects processing and all master bleed from the kick, snare, and other channels:
Snare Bottom: -42 dB
Snare Top 1: -6 dB
Snare Top 2: -14 dB
Kick Outside: -17 dB
Kick Inside: -6 dB
Toms (Low-Mid-High): -6 dB
Crash Cymbal: -6 dB
China Cymbal: -0 dB
Chinese Splash: -0 dB
Ride Cymbal: -0 dB
Hi-Hats: -0 dB
Drum Overheads: -9 dB
Room Mic: -18 dB
Ambient Mic: -24 dB
Master Level: -6 dB
Bear in mind that these levels are merely what is needed to avoid bleeding; but the intra0kit levels do matter further down the signal path of course (e.g. inside/outside kick ratio, and the base point for various overhead mics relative to the direct signal before applying the individual trims on the overhead/room/ambient sends).
I record each kit piece separately, and record the OH, Room, and Ambient Mics blended individually into each kit piece track using the personal blend settings listed below:
Kick Drum: OH Mic Send -1.5 dB; no Room or Ambient send
Snare Drum: OH Mic Send -1.5 dB; no Room or Ambient send
Toms: OH Mic Send -9.0 dB; no Room or Ambient send
Hi-Hats: OH Mic Send -7.0 dB; no Room or Ambient send
Crash Cymbal: OH Mic Send -9.0 dB; Room Mic Send -1.5 dB; Ambient Mic Send -9.0 dB
China Cymbal: OH Mic Send -9.0 dB; Room Mic Send -1.5 dB; Ambient Mic Send -9.0 dB
Chinese Splash: OH Mic Send -9.0 dB; Room Mic Send -1.5 dB; Ambient Mic Send -9.0 dB
Ride Cymbal: OH Mic Send -0.0 dB; Room Mic Send -12.5 dB; Ambient Mic Send -9.0 dB
Bear in mind that this is a Dub kit, which combines elements of Ska and Funk and is dry.
Everything is center-panned in BFD, and I pull everything in as a mono channel (summed).
I do quite a bit of tweaking to individual kit pieces, for resonance, tuning, etc., but didn't list any of those settings as they may not be pertinent outside BFD (I don't think other drum VI's give so much control).
I spent several weekends trying different approaches, but ultimately concluded that I could most closely emulate live drum tracking by working in mono only and using the various overhead mic contributions on a per-track basis, setting the ratios in the BFD setups.
Many prefer to mix in the Drum VI, but I find that this approach quickly gets confusing and problematic in terms of signal path and later plug-ins as well as phasing and the overall stereo image of the VI's drum set.
The approach above would need to be tweaked on a per-kit basis (and per genre/context), but it is foolproof in the final mix.
You could separate out the OH mics into their own channels, but I found this started to mess up later in the signal path so decided that it's better to blend in the OH's as needed in the drum set mix window inside BFD (with careful listening).
This saves work and time on future projects as well.
Within Digital Performer, I apply compression, EQ, some Oil Can Delay to the Snare and Hi-Hats (this being Dub), pan settings, etc., with no worries about stereo imaging getting fouled up. The various overhead mics provide some natural reverb and only a little Post-Production Reverb is added afterwards to the Kick, Snare, Hi-Hats, Toms, and Ride Cymbal.
Within DP, here are my pan settings for this specific kit, which is meant to sound full:
Kick Drum: C
Snare Drum: C
High Floor Tom: 8R
High Tom: 4R
Low Tom: L4
Hi-Hats: C
Ride Cymbal: 12R
Crash Cymbal: L12
China Cymbal: 2R
Chinese Splash: [ on paper somewhere -- not used in the song I referenced just now ]
I can't understand how anyone could make use of any presets in any Drum VI that I own or have tried, as they all bleed way over -0 dBFS! This is especially true of Kontakt libraries.
