Re: LP-BP-HP filter
The short answer is no, it would be good if you could do that. The easiest thing you could do, is put in an extra filter board for an op-Amp based filter in addition to the x0x LPVCF, but without a lot of extra work it would not be voltage controlled, or have a variable resonance like the x0x VCF. You would need to use something like an OTA (different type of op-Amp), like the BA6110 in the x0x or a CA3080 or LM13700. Checkout the datasheet for the LM13700, it has a part on VCF's:
