May not seem like it from the numbers, but this is a major update. The UI refresh reflects that it's part of the H9 Live series, and adds support for the Tempo section update, but the biggies are NKS compatibility and, drum roll, the ribbon is now MIDI-Learnable! No more convoluted workarounds to automate the ribbon or connect a hardware control to it! Woo hoo! Just tried it. Works fantabulous!
