Hello, I have the Faderport2 since early September.The original firmware version was V3.01.Je work with several software: Reaper / Audition cs6 and Mixbus. My software is Mixbus and everything worked in protocol MCU (Logic) until I face the firmware maj in V3.21. After configuration of the control surface, no further action of the faderport. On the other hand, it works well in Reaper and better in Audition cs6 using this same protocol MCU (Logic). Thanks in advance for your help.
