Yeah, the Moog is super fat but no downsweep and limited envelope shape options (unless using CV) though I have a build idea which, if it works, will solve this, whereupon I’ll rebuy the Moog.
By the way, I like the colouration that the Moog gives in bypass mode.
For formants, check out the Future Impact for sale from the same seller. Also, Glou Glou’s new Pralines will do formants as it’s 4 parallel BP filters with individual frequency control.
Glad you’re enjoying the Manta. Please share some patches on the dedicated thread when you are able to.
