True observation!

That is a very important point.
And also the other way arround.

vco->vcf->vca is not so good for emulationg a resonating effect,
like the body of a guitar. It should be vco->vca->vcf.
The vco->vca emulates the plucked string (in this case the vco should
jump to the highest point of the wave, the string is strucked),
the vcf (not necessarily a lpf, better a resonator bank) resonates
allong, with it own response, even if the string is muted.
Doing it the other way would mean to truncate the vcf resonance.

This way the S/N ration of filters IS an issue, because the
input has high dynamic range, and the filter is always ON.
