[sdiy] saw vs ramp, audible?

[Brother Theo]

Strictly speaking as a tone-deaf engineer, a ramp and a saw will have the
same harmonic content and therefore sound the same. However if you take one
oscillator making a ramp, and a different oscillator making a saw, they
could sound different because they are different oscillators and could have
different harmonic content.

Other minor differences could occur downstream as components such as
capacitors could react differently to a ramp and saw. Perhaps that is what
people are hearing when they hear a difference.

Now if you really want to talk about differences, which is better? A saw
core VCO, or a tri-core VCO that makes a saw (or ramp) from the triangle?
