[sdiy] More questions from the hack: low frequency cutoff of vco?

[TooManySynths]

Hi All,

Sorry to be a pest.  I suppose one of these days I
should put the soldering iron down and find more time
to study.  Anyway, I'm trying to scale down the
frequency of a simple VCO.  It is, in fact, one of the
tone osc in the tama techstar.  I cannot seem to get
the VCO to oscillate lower than about .5 hz.  Again
the schematics are on Florian Anwander's page.

I am only beginning to understand how VCOs work and
other than putting in a larger timing cap or feeding
it a lower control voltage, I'm not sure what to
change in the circuit.   I would like to get it down
to about .01 hz or lower to use as a VC lfo.

Since this is, I'm quite sure, an elemetary question,
please respond privately.

Thanks
Daryl
