it doesn't really concern puredata, but it's interesting, <br>
have you tried to drive the signal from your soundcard with an op
powered with symmetric power supply +-5V for VCF and +-2.5V for VCO
EXP ?<br>
<br>
it can be done by using a battery or universal DC supply with
virtual grounding:<br>

<br>
the op could be wired like this:<br>

then replace the pot with resistor that gives the right cv range<br>

Manipulate amplitude for CV frequency. Gives you about 1 octave
