They don't affect the frequency, but the waveform converter might get too
slow to follow the feeded triangle wave.

I don't have the schemoe of the CEM-Filter-Modules here, but at
http://www.synthtech.com/cem/cemdata.html you might find the Datasheet of
the CEM 3320. There you see four caps with 300pF called Cp; decreasing
their value will affect the tuning.

There are no data regarding max frequency, but to me it looks like only the
first two pages of the datasheet - I remember them longer.
