It still sounds like a bass and sounds great playing along with stuff. So don’t fall into the trap of thinking it’s substituting a bass, it’s a different bass that’s all. Still sounds ‘bassy’ and fat. An octaver adds options, one of which is normal bass range, but even with a polyphonic octaver with perfect tracking it’s not what these are all about imo. They’re simply great fun and hugely flexible/inspiring and of course amazing for synths!
