> Anyone who has used a real Tb-303 will know that the measures taken to
compensate for the volume drop at high resonance are marginally effective
at best. The volume all goes through the roof when you turn the resonance
down to zero!

Not entirely - due to other imperfections, the bass drops several decibels
when the resonance is turned down to zero. This gives the characteristic
and somewhat nasal in-your-face midrange of the non-resonant TB with open
filter. :-)
