I'm wondering what was off with your original, 12 year old approach - it looks to me like "(maybe-not-bandlimited?)-saw-tooth-through-a-vcf" basically turned into "bandlimited-saw-tooth-or-sometimes-a-square-through-a-vcf." Doesn't look wildly different, but maybe the envelope and portmanteau had a big impact? Sounds pretty much like a 303 to my ears.
I think you're right about all of the above - the band-limited oscillators, envelope, portmanteau etc. It's those bouncy non-linearities that lend the 303 it's characteristic sound.
I did a bit of research to try and re-create some of that. My envelopes are control-rate and I didn't really get the non-linear resonance "memory" effect happening I don't think, so it's not that faithful a reproduction, but good enough for algorave dance floors it turns out.
Cheers,
Chris.
