Solved Error msg Sample Rate 50182 [SOLVED]

[offtheroad]

After I just upgraded to Yosemite 10.10.3 I get this Logic Error msg: Error while trying to synchronize Audio and MIDI. Sample Rate 50182 recognized. Check conflict between Logic Pro X and external device. MOTU Ultralitemk3

If the issue disappears when you switch to built-in input and output devices in Logic's audio preferences then that points to a possible issue with the MOTU driver. You could contact MOTU to see wether they're aware of the issue with their drivers and 10.10.3?

Yes thanks, when I disconnect MOTU and just listen thru Mac internal spkr it's no problem.

It looks like MOTU may have to update their driver for 10.10.3 then.
