Thanks brock, a few things:
1. The 100% wet sum-to-zero but was only a bug in Harmodulator, this wasn't a problem in Harpeggiator that I'm aware of.
2. The 'dot' is intentional on our part, and you're right about it's meaning.
3. The encoder nuance in Bank mode for Diatonic and Quadravox is also intentional.
