you surely sound like you can't do good music without your "pro-VSTis".
:insert proud looking psi smiley here:

I could of course, like i did for many years, but my job is much-much more easier and the possibilities are more "wider" now that i've discovered the technology. It's not just about "my personal pro-VSTis", but with most VSTis and VSTs in general. Think about it, if you got sample, you are mostly "stuck" with the given sound. You can't finetune or reshape it totally for your needs. Also the sample will mostly sound exactly the same every time you will play it, but the VSTi can be dynamic and can change the structure of the sound with every new note (or time based). That could give a much more "living" experience to the listener.
Don't get me wrong, i love the cool small (and even the big) mods too, and highly value the creative tracking skills from any person. But personally i'm just more like a freedom friendly tracker, than a (strict) restriction lover. And i am far from disregarding the sample usage, just not preferring it recently.
