Has anybody experience or heard of the W/S AD or other Korg products doing a reboot automatically. The screen goes blank, pulsing noises are heard from the audio outputs, then the KORG logo appears. This seems to happen more often when I am either sequencing or programming a new patch or performance so I wonder if it is software related? Has anybody heard of upgrades for "buggy" wavestation software or does this sound like a power supply problem? Please Help!
