I understand you weren't directing that towards me, but I maintain man, you need to lighten up and allow your perspective to be changed a little.
I'd say that exactly what it sounds like, and unfortunately it's to your discredit. You have to be careful when flaunting opinions that are based solely on ONLY YOUR perspective. Maybe money is not an issue to the "newbie", maybe it is; either way it doesn't matter. It still doesn't mean that you're in charge of dictating that he absolutely does not need to buy Omnisphere, or any other piece of gear. Let it be his choice. Let us make suggestions, but let him do his homework and make the final call. It's fine to say "well, I'm on a limited budget, and so far these things have worked for me" but that's all you have the right to say in all fairness. I mean, I started out using nothing but FL default sounds, and free samples/synths that I had scavenged from all the 5 corners of the internet. And while I'm happy with my past work, I wish to hell I had some of my current plugins when I made those earlier songs.
Here's another thing. How do you know that you can do everything with a free synth that you can with a commercial one? You don't. You can probably draw conclusions that there are free VSTi's out there that seem to be able to do what some of the commercial ones do, but in many cases, the free ones also CANNOT do what many of the commercial ones do. And you know what, as my collection has expanded, $500 doesn't seem like all that much to me, especially considering the content that something like Omnisphere contains. I know I don't have to explain the difference in hardware vs. software (costwise), but just as a clear example, let's take, say, the Fantom G. You're looking at going on $4,000, and it doesn't have NEARLY the quality or quantity of sounds that Omni has. And considering that Omni will probably be usable for the next 20 years (or more), $500 is not too shabby. Heck, buy an Xbox, a controller and a couple games and an XBL subscription, that's easily $500 right there. And quality music plugins these days are likely to have far more staying power to a composer than an Xbox has to a gamer. So the moral of this paragraph is - cost is relative and subjective to different people's perspective/priorities.
You'll also notice that generally, most professionals in the music industry own high-end plugins. Is this because they're rich and snobby? Doubtful. Rather, there's a good chance it's that these high quality plugins save them time as well as provide them with access to sounds that are immediately playable and inspirational right out of the box. I'm pretty sure that Hans Zimmer or John Powell (etc etc etc) Don't exactly have time to sit around and find an obscure sample and tweak it and retweak it and tweak it some more until it sounds close enough to what they want. They don't have time for that shit man. Especially when they have a deadline fast approaching, and an hour or two's worth of music to produce.
All this venting out now, I will say that I do not think there is anything AT ALL wrong with DIY music. It's completely fine with me if guys like you and CotMM and analoq want to make your biscuits from scratch. But you simply can't go around doing nothing but put down plugins just because you say you're too cheap to buy them (your words, remember?). You're only making yourself look bitter and resentful ON TOP OF elitist.
I will also say that I personally feel like presets should generally be used as a tool/template, and that it can definitely come across as lazy/cheap to do nothing but construct a song with them. Hearing a song that's just a bunch of default Garageband loops is definitely a turn off for me. However, that doesn't mean that every song I hear that uses a Garageband loop deserves to be shat on and ridiculed.
I know this rant has come across as SERIOUSBUSINESS and I know you have a bit of jest in you when you talk about this stuff, but once again man, lighten up a bit. Save the condescension for when it's really merited and not simply because someone wants to buy a synth that you don't like/don't need/can't afford. I like you a lot man, but you need to hear this.
[TL:DR - BGC rants about people who think commercial plugins are evil, and why they are not.]
