True, if you require all the speed you can get. An alternative approach is
to take a look at the actual circuit, decide which nonidealities are
important and replace everything else with ideal components. Then it's
often quite easy to construct a digital model of the circuit that performs
the same way as the analogue. The downside is the need for pretty heavy
oversampling.

I've modeled Korg MS20 (Rene Schmitz's version) this way and it certainly
sounds different from the filters in softsynths (haven't been able to
compare to hw dsp synths but thus far they've not impressed me). The bad
thing is that it requires about 8x oversampling for self oscillation to
work so it's a cpu hog.

Ps. Monowave 2 sounds pretty good. How do you deal with the aliasing
    caused by the wavetable oscillators?

Pps. Anyone care to explain how moog ladder works?
