Messenger is my sixth synth, I have the latest firmware, but I'm must say it still needs some work from Moog team. Has issues with syncing to midi clock, at the current state it's almost unusable on the stage. Not sure why Moog decided to feature it with USB C interface, when most synths use USB B, which is more affordable and you can easily find longer cables around. Overall sound quality is very good, but still limited on synthesis capabilities, yet for this price it is a great entry-level Moog synth.
