Now I'm not a super synth expert, also not in sound design with such.</div>
<div>What I've always wondered, if I look at VCO circuits, why people go to the lenghts that they do wave-shaping a more or less pure sine as a waveform output, my heart ached when I saw a circuit that used an OTA + yet other stuff just for that.<br>
What more does a dedicated sine output provide that one can't get with using triangle -> lowpass VCF with keyboard tracking on? So maybe it doesn't shave off all harmonics totally, but is the sound difference really that big?</div>

<br>
I'm curious what figure is the current state of the art.<br>
