The Octopass is a serious contender if you're chasing that classic Moog filter sound in a Eurorack format and need polyphonic capabilities. It's a fantastic workhorse for sound design and sequencing, especially if you're already invested in Tiptop's Polytip ecosystem. This module shines for those wanting a focused, powerful filter without the complexity of a multi-mode behemoth.
