I was the early adopter when Quicco Sound had a Kickstarter going on for their Mi.1. At first, it just could not handle all the cc#11 from my midi accordion on multiple channels. After the firmware update, it works great though the very 1st generation of the Mi.1 which I have can not be updated to the lastest version of firmware because it requires new hardware. Then again, I can never choke my Mi.1 after the firmware update.
