Like a user below (I wanted to start a new topic to upvote that issue) my MF simply will not accept midi signals from my DAW. I've played with every setting, switched cables, ports, midi channels, USB vs DIN, tried a different DAW, etc., and still nothing. It sends midi (although it can be very glitchy and temperamental), but no dice on receiving. I just got this yesterday, updated the firmware, etc. Two other Arturia devices work fine with my system, as does all my other gear. I've been using midi since the late 80s, so I don't think I'm missing anything...
Not sure whether this is a QC hardware issue or a software bug, but I'm very disappointed with such a basic flaw. I already spend half a day trying to fix this, and I've just about had it. Grateful if anyone else has advice (or a similar issue), but this is probably getting sent back. I can only infer that Arturia rushed this to market because of the hype, and it wasn't ready. I've also noticed some other, more minor bugs and glitches as well.
