Some of us like the sound of analog because of its continuous (un-encoded) signal - not
because of sloppy or low-quality product designs.

BTW, do you think digital doesn't add color and impurities too My studio is full of digital
products that add all sorts of audible (unintended)) color and impurities to the sound.

If you sell a VCO that can't make a decent sine wave - maybe label it something else
instead. Sine actually means a wave with NO ADDED COLOR OR IMPURITIES.

My 143-9 doesn't track anywhere near well enough to be useful as a VCO. It's intended to
be used as a LFO.
