Better idea: lose the Shifty and the Jove VCF. Replace the Jove with G-Storm's 8 hp version of the Jupiter-6 filter (which I definitely endorse the use of, given that I've got an actual JP-6), then you'll have the 12 hp for the Quad VCA. But the thing that worries me, looking at the above, is that the build currently has NO VCAs...and that's just not going to work out nicely. So what I would suggest is to grab two different 6 hp VCAs: the Happy Nerding 3x VCA (linear - for CV/modulation work + mixing) and an Intellijel uVCA II (dual VCA, adjustable for either linear or exponential [audio] response, plus 2 channels of mixing). That gives you five VCAs and two mixers in one shot. Keep the 2hp modules...I think you're apt to find them rather useful.
