Yes, it’s polyphonic... and it tracks beautifully, although that’s probably not the right word for it. This is an oversimplification of how the technology works, but it’s truly more like an effect pedal than a synth in that it colors the whole sound (whether a chord or single note). Because of that, it even “tracks” fine with string bends. I don’t have that one, but I have the C9 Organ Machine (same technology, different sounds) and it’s freaking sweet. It’s REALLY badass when I use it with my 10-string.
