Hi Sacguy71,
Ah... such a pity, I see I am too late with this message. In your title you mentioned you ordered already the Erica Synths - Black Polivoks VCF, if you can perhaps you try to exchange it for the Black Dual VCF. I got both filters, first I had the Black Polivoks VCF and I wasn't impressed, perhaps it's just me and I am using it wrong, that might be. So I gave up on Erica Synths regarding filters, though for some reason I gave it another chance and still ordered the Black Dual VCF. Oh what a beauty that is. It's very enjoyable using this dual VCF and can provide so much fun and pleasure, totally the opposite of the Polivoks VCF in my opinion.
If it's too late for you to change the order then I hope you can use that Polivoks filter better than I do. If you get some successful nice sounds out of that Polivoks then please let me know how you did that :-)
Have fun with the rest of it and kind regards, Garfield.
