Catalinbread Perseus?

Do you happen to know what circuit the Catalinbread Perseus is modeled after, or modified from?  It has a little blue box flavor, but glitchy.  I'm curious if they use biasing for the octave or a flip flop.

Thanks,

The keywords in the product description would appear to be "monophonic" and "glitchy".  Flip-flop-based octave division need a mono signal, and the signal needs to be above a given threshold voltage.  When it hovers around the threshold, some consecutive peaks may be sufficient to result in flip-flopping, and others won't.  That's where you get the glitchiness.

Catalinbread touts the great tracking of the unit so I gather they/he did something a little extra/different to deliver a more consistent signal to the flip-flop.  I guess think of it like a tweaked OC-2 or Blue Box.

Thanks Mark, that answers my question.
