I've been working my way through your comments.
Sorry, I meant Wasp for a filter. I think you suggested I try to maintain 3 filters, so to replace the 18hp Qpas I could put the Wasp and Polaris by Intellijel (looks pretty good). If I needed to save 2 hp I could go with Ripples 8hp and wasp 8hp for a total of 16 hp; saving 2 hp for another envelope.
So here is where I'm confused. You asked if I needed another ADSR (Synthrotek) but believed you would add another envelope. I thought ADSR was an envelope. Could you explain further? What am I looking for?
