I've been very intrigued with the Second Voice since first hearing about it, but have been turned off by reports of the noise issues on older models. According to some reports the newer versions have cleaned up the noise alot, as well as added several very useful looking new features. Anyways- I am wondering how serviceable it would be tracking-wise as a suboctave? Is it always a bit glitchy or can it be dialed in to handle tracking similar to something like an OC-2 or Copilot Cubic? I am also interested in the Octave up for a couple parts in my band, so open to reviews of that as well! Also- my understanding is that the newer version has a dedicated Octave down, so if I wanted to use an Octave up for a song and switch to Octave down for another I would just have to fiddle with the Octave/Harmony volume controls right? Thanks for the help!
