I have been using the included PSU for a while with no issues, but today, it powered up and the oscillators sounded pitch modulated, even on an init sound. The resonance had an interesting fizzy quality that isn’t expected. I tried a ton of stuff but nothing helped. So I grabbed my beefier Apple PSU and used it to drive Mono and it works perfectly. Did my included PSU just fail? I know others have complained about quirky behaviors related to PSUs and computer bus-power. Suggestions?
