Gosh, I'm glad I'm not the only one given to somewhat long-winded semi-tangential philosophical ramblings!
I feel like the analog modelling paradigm is driven to a significal extent by marketing; it's really hard to convince people they need 27 more EQ's and compressors when they already have several perfectly good ones,
*unless* you can convince them that what they really need are faithful models of great historic gear that most of us have never heard or used - but which will, like magic pixie fairy dust, sprinkle awesome analog vibes all over our tracks. It doesn't just sound good, it sounds
*authentic*, and by extension your tracks will have
credibility that simply can't be achieved without the Special Magic Sound of the very same legendary processor used by, well, you get the idea.
I am probably about as susceptible to this as anyone, and as a result I have some great stuff that in actual fact I only use occasionally... if I want to quickly dial in a bit of simple compression or EQ, I'm quite likely to use the ones already right there in the Pro Channel, unless I know I'm going for something specific, say a heavier saturated compressor like NI's Supercharger GT, or the sheer retro character of Waves' TG12345... But for bread and butter purposes, the PC is right there, and sounds pretty darn good, and I highly doubt anyone who hears the track is going to say oh, I'm not into this, he's clearly using stock plugins. They will like the music, or they will not; if I make it sound as good as I can with
whatever tools get me there, hopefully the former is a bit more likely.
That's not to say there aren't some really excellent products that have emerged from the modelling approach. We have, in fact, an embarrassment of riches, and they're getting better all the time. I think it's a bit silly to pretend that UAD and Waves are the only companies with the resources to do serious component-level modelling; certainly I've seen about 30 companies making the claim, including IK, PSP, Softube, Overloud, UBK/Kush... it's not like these units are *that* hard to get access to. And then there are a number of developers that don't go down the road of modelling specific gear but rather make great-sounding, useful and well-thought out plugins that may or may not aim to capture the essence of analog/tube/tape/whatever - like McDSP, FabFilter, iZotope, Soundtoys, Flux, U-he, Blue Cat, Voxengo, Klanghelm, the almost unbelievably prolific Melda, Valhalla, Klanghelm, Toneboosters...
I also think it's a bit silly to pretend that using plugins that very exactly model specific gear from the past is the only way to raise your game production-wise. It's one way, or rather could be part of one way; however as per one of my previous posts, having and using those products is not going to magically make you a better mixer, all the marketing in the world notwithstanding. But it's also completely possible to raise your game in terms of skills, and achieve completely professional results, using only the tools in Sonar. If Andrew Scheps or Chris Lord-Alge or Butch Vig or (insert your favorite pro engineer here) were trapped in a studio with an artist worth recording and only Sonar Platinum, do you think they would not be able to make a great-sounding track? Not pretty-good-but-would-have-been-better-if-only-they-had-better-plugins, but flat-out great. I'm pretty sure they could do it. Real engineering knowledge and skill has little to do with knowing what gear sounds great (though that certainly helps), and everything to do with highly trained ears and the ability to use the basic tools of our trade to make things sound better.
I'm not pretending to be an engineer on anything like that level, I'm fundamentally a musician who got into synths and recording back in the analog days and have nursed it along as an interesting and rewarding hobby that more or less pays for itself and keeps me out of trouble. I do like it when things sound great, rich and warm and detailed and tonally balanced... but I also know that many classic, important and influential recordings were made with limited gear, limited skills, limited budgets, but lots of attitude... and it's hard to find that in a plugin.
