Well, here’s the deal then …
There’s been a lot of finger pointing at B, that’s actually the only True VCO, it’s not a prince of VCOs by any means as it’s the Doepfer one baked into the original Dark Energy and that whole synth voice sounds very very fine to my ears
A was the Saw from the A4
C was the Tri from the A4 with PW@32 (a nicer fuller saw style sound imho)
I guess the point was that the ‘dull’ oscillator theory banded about a bit on the other thread has some room for interpretation … to my ears, when I was A-B-ing with this little test setup, all the magic became obvious when the DE filter was introduced, it was just more satisfying in some regards even though the VCO sounded a bit less clear than the A4 ones … where it shows is that the mid range saw shapes are much of a muchness, but when you drop down, the a4 shape tickles the highs more and you don’t get the roundness/fullness you do with the ‘duller’ VCO on the DE or even the Tri (mod) osc shape of the A4
I guess the point I wanted to get across was that there is scope for a nicer saw (imho) and that the osc wasn’t really the only big player in the overall sound stakes in terms of raw appeal
I’m not disagreeing with the perception that the sound is sweet spot dependent, it’s just too flexible to sound ‘right’ in all the ways it is malleable … when I fire up a MS20mini and adjust that, I struggle to get something that does not sound glorious … a factor of the core design and the seeming simplicity
The A4 filters can also be used to create big basic sounds if you tweak wisely, it’s just a bit more prone to going beyond the sweet spot and thus the frustrations … but wrt the above thread, there may be less to derive from opting for an average vco of a similar type
I was kinda hoping people would rate them as C > A > B to promote a bit more thought about what the A4 can deliver, but there’s no doubt that the DE VCO has a better low end saw than the A4 saw although the A4 saw (A) may seem more pleasing than (B) … I certainly prefer the adapted Tri because it offers more interesting ‘pulsewidth’ destinations for the same core osc shape, the transistor pulse is also a great shape
