it doesn't really concern puredata, but it's interesting,
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 ?

it can be done by using a battery or universal DC supply with virtual grounding:

the op could be wired like this:

then replace the pot with resistor that gives the right cv range

Has anyone been experimenting with the Moog Werkstatt? Looking for simple PD-based CV control? Minijack from computer, left channel to VCO EXP IN, sleeve to ground. Manipulate amplitude for CV frequency. Gives you about 1 octave range.
