Multimode filters are nothing new but this one takes its inspiration from some of the earliest examples. Like the ARP 2500, EML 101 modular and EMUs UAF filters before the Modcan Multimode uses discrete OTAs in place of CA3080s or the more recently popular SSM2164. The result is a rawer sound with a lot of resonance.
Our version of the Multimode does not self-oscillate but does get louder as resonance is increased.
It does represent a unique flavour of Euro filter.
