First, as always, a big thanks to Eventide for making great products. And for listening to customers as they develop improvements and new features.
I agree that polyphonic pitch shifting would be really nice. There are a number of algorithms that have a flavor of pitch shifting. But I do feel like many of them suffer because of tracking issues. Implementing a better pitch shifting capability would be a very nice addition that would span many algorithms. It seems like something that is well worth doing. While I think the H9 does many things extremely well, it seems to be a bit behind the times in terms of pitch shifting. There are a number of other pedals that seem to do a better job.
