Carbon vs Carbon 2

I use and like both--apart from the name and the very broad design ethos of being subtractive workhorse polysynths, they're really very different in terms of their structure, sound, and capabilities. Carbon 2 has a somewhat more typical, modern workflow (albeit involving a very compact interface owing to the tabs you have to page through) and incorporates some niceties like simple wavetable oscs, a few more modulators, and a more comprehensive suite of FX; and as you noticed, it handles aliasing better on account of the more advanced and, for the time, fairly state-of-the art core-based antialiased oscillators. But I dig OG Carbon for what it is, as a stalwart of funky, pre-v5 weirdness, and there is a certain hipness to that. I kind of like the odd decision to have separate oscillators for Square, Saw, Sinusoid, and Noise with a different palette of "special effects" for each. Of course its architecture is strictly Primary-only, and it shows. I run Carbon at 176/192kHz to mitigate the crustiness from aliasing in the oscillators, very crampy filters & EQ, etc., and given its age, it's lightweight enough that modern CPUs can take that kind of blunt-force solution in stride (alternatively, you could embrace that as part of the "vibe"). But like colB said, these are both old, old synths and sound the part--love them as they are, or if the sound and/or operation isn't doing it for you then look elsewhere.
