Oddy-Free is an emulation of an Arp Odyssey Mk.II - much attention to detail was given in the layout of the signal path to have it behave as accurately as possible. It does have just a touch more umph than most originals would - this particular emulation was based on the "illegal" filter versions based on Moog's -24dB Low-Pass filter, so it sounds quite a bit smoother and richer but at the same it can produce the harsh metallic tones known from the Odyssey.
