So, what in effect are you saying with your assertion that you guarantee that George Martin and Glyn Johns wouldn't use realistic amp sims or multi velocity layered drum samples triggered by the latest multi velocity V-drums ?
Are you saying you can tell the difference between recorded mixed and mastered tracks that use that amp sims and V-drums and recorded mixed and mastered tracks that use real amps and real drums ? Can you provide instances pls ?
I think the mistake people make in assessing amp sims is that they compare the sound coming out of their monitors to the earth moving sound coming out of their own real amp cranked to 11 in their own space with its own colourization.
I think the mistake people make assessing Addictive Drums and Superior Drummer 2 is they dont understand how they are operate. They use dry, unprocessed samples recorded at many velocities ( 12 gig in the case of S2) . They then offer a mixing section where eq, compression,microphone bleed, other fx and a sound stage using convolution reverb can be applied - essentially giving anything from a garage to stage, to a highly processed, polished studio sound. Played through a decent set of V-drums and I challenge you and them to tell the difference.
I know this thread has gone pretty far afield, but since you specifically asked about this post in The Cave, let me reply. First, yes, I DID miss this the first time around - I started back at Page 3, saw how much of a tangent the thread had gone on, and didn't bother to pick up where I last posted. Sorry.
Well, like I said, my original assertion was too strong. I think a fairer one is that, especially since the guys whose names you mention are really pretty old-school in their production ethos, that given the choice I'd be very surprised if they
chose amp modelers and drum sequencers over live amps and drums. Glyn Johns in particular is well known around these parts for the drum micing technique that bears his name, that yields excellent results (given a well tuned kit) in even average-to-mediocre spaces. I can't speak for the man, obviously, but as long as he had a good drummer and at least an OK room to track in I do think he'd prefer to go with live drums.
As for as amp modeling... I'd say that while modeling keeps getting better (the Fractal
AxeFX in particular is supposed to be excellent - a buddy just grabbed one to use as a FX processor with his Mesa Roadster and I'm looking forward to spending some time playing with it, more on that later) and that it's possible that at one point this will change, in the past I'd say that I've been able to tell with statistically significant frequency when an amp is modeled vs real. The biggest issue in a recording, I think, is speaker emulation, and while impulses are getting much closer they're not 100% there yet.
I think the best example I can giv e you is a pair of Porcupine Tree albums - "In Absentia" and "Deadwing." They were released only a couple years apart, and mixed and produced by Steven Wilson, PT's singer/songwriter and by the time he did these albums already pretty mature behind a mixing board - he got a lot of attention for his work with Opeth, outside of his own band.
I was already a big fan thanks to In Absentia when Deadwing was released, so I grabbed it the day it came out. The material was awesome, the production was just as good as I'd expected of Steven Wilson, but the one thing that kind of surprised me was that the guitar tones just seemed a little lifeless compared to In Absentia. Everything just sounded too... Idunno, the cleans sounded a little rubbery, the distortion was a little indistinct in the midrange and papery in the high end, and it just didn't seem to hit you the same way. It wasn't until that weekend when I got to check out the bonus material on the disc, including some "in the studio" videos. Sure enough, Wilson was running a Pod into a Marshall 4x12 for most of his guitar tones. He wanted to prove the point that modelers could be just as good as real amps. I don't think he succeeded (and he was back to his Bad Cat rig by Fear of a Blank Planet), but what I DO think he showed is a good engineer with a good ear can definitely get serviceable results out of modelers. However, I also think he showed they're not 100% there yet.
Live in the room, no question - Amp sims aren't there yet. There's also that intangible "feel" aspect - my buddy who just picked up
the AxeFX plans on using it for recording (and as he screws with it he's getting more and more believable results), but he tried to exactly replicate the front end of his Recto Roadster with a couple of the Roadster models, and every time he did, he'd flip back over and run through the amp preamp and just realize the modeler couldn't quite compare. The question of course is how much this matters - in a recording situation, does it matter how an amp sounds and feels in the room, vs on tape? For some guys, not at all, for some it does - if the "feel" of a particular amp is part of what you like about it and inspires you as a player, then switching from the amp to the modeler will impact your playing somewhat, and that could be an issue.
I've never gotten the opportunity to try a drum sequencer hooked up to a V-drum kit, but I will say that I recently picked up EZDrummer, and that I'm rather impressed. For the album I'm working on I'll still be replacing
my EZDrummer scratch tracks with live drums, but it's a pretty damned cool tool.
That said, again, you trade some flexibility. If you have access to a particularly awesome sounding kit, then you lose that by going with samples. Likewise, you trade a lot of flexibility in the ability to tune or treat a kit to get it to work for the sound you're after - you have a number of stock drumkits to work with and that's that. You also lose the ability to work the room - if I recall right, the "When The Levee Breaks" drum part was recorded at the bottom of a stairwell. sure, you can try to replicate that with plugins, but it's tough to beat a good natural 'verb for realism. And finally, there's a lot of stuff you can do with a drum kit that more likely than not won't be sampled - hate to mention Porcupine Tree again simply in case they're a band you've never heard of or hate, but their drummer (who's a monster) does a lot of fills on their quieter stuff where he's drumming on the side of the shell, sort of like a side-stick technique on a snare. If there's a way to do that in EZDrummer, I haven't found it.
So again, while I grant you the possibility that the guys you name would work with modelers or drum samples if it happened to fit the sound they were after (for example, amp modelers slay for industrial/electronic metal and that downtuned "djent" sound guys like Meshuggah are after precicely because the attack is NOT 100% natural) or due to constraints beyond their control, I don't think it's unreasonable to say that especially the old-school names you mentioned would prefer to use live instruments over digital. Not 100% of the time, not "no way in hell," but just that it would not be their first choice for the vast majority of situations, and given the OP's question it's not the route I'd advocate.
