Hello all... I am a brand new Maschine user. I don't have a complicated setup by any means; Macbook, headphones, and of course an MK3. I have only had my MK3 for 2 days. I unboxed it, plugged it into my Mac, turned it on, and was able to play and hear everything thru my Mac's speaker! I am very happy!! I had to go to work so shutdown everything... I came back to it and everything was working fine the same as before. I begin watching tutorials for beginners and went about downloading an expansion pack. At some point, I got an alert in Maschine that a firmware update for the MK3 was available. I downloaded it. Installed it. It restarted. I went back to use the MK3 after the firmware was updated and the expansion pack was installed. I immediately ran into hearing NOTHING. I could see everything in the Maschine and on the MK3 working exactly as expected only no sound what so ever. Start/stop projects in Maschine or on the MK3 and watch them both work as if I had muted my system; however, I could hear sound from other NI instruments like FM8 and Absynth just fine. I literally only installed those two things. I don't think I even touched Maschine or the MK3 during the installations. At this point, I am very sad. I read a bunch of stuff on how to fix the problem but nothing was exactly the same problem and nothing worked. Every setting change I made during this process was undone as soon as I determined it didn't work. I rebooted my Mac with the MK3 plugged and not plugged. I tried also to use the MK3's headphone jack no difference in any configuration. I have no idea what else to do or try. Any of you much experience users have any ideas or recommendation? I would really appreciate any help anyone is able to provide. Sláinte!
