Well. So I just got the MB 3 weeks ago. Worked well so far. But yesterday I installed the MB Connection software, downloaded from the Arturia website. And after I updated the firmware, as suggested, the MB won't emit any sound. Keyboard doesn't respond, neither does MIDI IN or midi trough USB. When I hit the Tap/Rest button the MB began to spit out random pitches every time I hit the button. But after a few minutes that stopped working as well. So now this 3 week old synthesizer refuses to make any sound at all. Kinda defeats the purpose.
Hoping for a response on this.
