You are wrong. There's no analog VCA for the oscillators. Software
envelopes
control the oscillator chips internally, so in a way vca for each osc is
_before_ the filter chip, where two sources are just mixed in VC mixer
and
passed to the vcf. Onboard VCA that wasn't needed for usual task was
misused
to give sorta 3rd VC mixer input by adding it's out to the ext audio
in in the vcf.
