Thanks for the tip on the ring modulator. It does indeed say that it can be used as an octaver. I'll give it a go.I figured that you might have a spring loaded pedal............And no there is no 2nd pitch block, I was looking at the wrong effects list on the wiki. But you could mess around with the 'Ring Modulator'. I believe that it can be setup to do the octave-down thing?
From the Wiki........
- Use the Ring Modulator effect in tracking mode (with Hi Cut turned down).
