Hi! Brand new to this forum, just purchased and received my first ER1 used! While making sure everything was functioning as it should, I noticed a low hum noise coming through my headphones during a few scenarios and was wondering if this seems normal or if I have a problematic device. My headphones are functioning fine on other devices.

So one example is when executing a Write to save a pattern of settings, the devices makes a brief 1-2 second low frequency hum. Not the end of the world. But the same hum also starts up when I hold Tap to mute parts. If there are multiple part indicator lights on at the same time I can hear that same hum only it’s the whole time I’m holding down the Tap button and muting/unmuting parts. It stops when I release the Tap button. Another example is when the Accent part is selected, and if more than a handful of the step buttons are lit it starts emitting a continuous hum. If I start removing accents so that fewer step lights are lit, the hum incrementally gets quieter and eventually stops when only a few are left lit. Same If say hi hats are sequenced on all 16 steps. If I select the hi hat part and all or most of the step lights are lit, the hum comes on. It’s unfortunately loud enough to hear over the top of while a pattern is playing. Sad

So through testing, it seems like whenever there are a lot of button lights lit, it starts the low hum. Im hoping it’s not a faulty device. Any insight if this is a known thing? Seems like some sort of low interference hum that is enhanced the more lights that are lit. Except when doing the Write command. That just does it briefly even without many device lights lit. But like the more energy it’s using, the more the hum. Could it be a faulty power issue?

Anyway, would love a knowledgeable opinion or idea of what might be going on. Thank you!

Mark
