I would choose IME Piston Honda MK2 over Kermit for your VCO. More musical and better options. Kermit excels as a quad modulation source since the oscillator is too harsh in most cases. I recommend put a case together here and share the link so we can help you better. You need support utilities like attenuator, mults and so forth. I highly recommend the Kinks and Links combo from Mutable Instruments or something like Links and WMD SSF Toolbox.
