Sometimes patches get hung up. When this happens the knobs or buttons no long have an affect on the patch. You can press Program or Bank buttons to advance to different patches but the sound will not change. The screen shows you have advanced thru the patches but still no changes in sound. When you put the unit to sleep during this the LFO buttons will remain lit and blinking at the rate that they were on the stuck patch. The only option is unplug the power cable.

Im also experiencing issues with dead keys.

I do not use the unit via USB except for updates (latest OS installed) and patch swapping. I use the analog outputs for sound and sequence it with hardware using Midi.
