MIDI Out Randomly dropping out over USB
« on: June 17, 2017, 08:58:58 PM »
Another issue I just discovered which seems to have something to do with the screensaver as well. When connected to a Mac computer via USB, the MIDI out transmission over USB seems to randomly stop working after the screensaver awakes. The only way to get it working again when this happens is to unplug the USB cable and reconnect it again (or of course, restart the computer). This is an especially troubling issue since I was also planning to use the Rev.2 as a MIDI controller as well. I've been able to reproduce this multiple times now on two separate units. I'm not sure at this point if the USB connection being Class Compliant has anything to do with it, since I've also noticed other odd drop outs with equipment in the past that were supposed to be USB Class Compliant. I will have to try plugging the keyboard into a MIDI hub with independent drivers and see if it does the same thing or not.
