The Mimetic has four sequencers in it. The outputs are not quantized. So a quad quantizer might be useful if you really want to use it for four pitched sequences. I'd really download the manual and understand what you will need to trigger the Mimetic and its range of functionality. It'll save you some heartache if it doesn't suit your needs; especially if you're using the Mimetic to send gates. (page one of the manual has most of the useful info). Download the manual.

Plaits doesn't have a quantizer built in. But if you use it with a Braids module... the Braids does. You have a Plaits. But a Braids might be better if the sounds work for you. Here's a link.
