this isn’t really serious issue to be honest but it’s something that might need to be just check out.
I’ll boot my 10.9.2 iMac Late 2012.
Then i’ll turn on the UR28M via the wall socket, then press the power button to turn it on.
If I load dspmixfx it always comes up with “No Device Found”
If I close down dspmixfx, then reboot my UR28M using it’s power button then reload dspMixFX it works fine.
This happens every time.
Not a problem, just annoying
