This is the perfect companion for Dionisi and Metamorf : Faderfox EC4 (https://www.faderfox.de/ec4.html). This is a faderbox that can send 14 bit MIDI CC messages, for fine resolution of frequency, without zipper noise. I updated Dionisi firmware to 2.2 (https://alfadelta.be/dionisi.html#downloads) and Metamorf firmware to 1.1 (https://alfadelta.be/metamorf.html#downloads). These latest firmwares also fix some issues with the quantisers.
