Loud beep in one loop in advanced mode beta

Just getting started with there ML10x and off to a bit of a rocky start.

I’m getting a strange issue when using any effect in either tip or ring of Loop A. I get a louder than guitar signal constant beep that changes pitch when moving volume and gain controls. If the controls are very low it goes away. It’s only present when in advanced mode beta, and even stranger it only happens when I bypass the loop. It goes away when the loop is engaged. If I bypass on the pedal itself it goes away.

I can’t replicate the exact chain, but the issue is not present when in simple mode whether the loop is engaged or not.

I’ve tried having it on its own power rather than daisy chained and this did not help. I tried various power scenarios but nothing fixed the issue.

I’m at a bit of a loss where to go from here. Any help would be greatly appreciated, thanks!

Hi! James just posted an update to the firmware that addresses this issue: Release Firmware v1.2.0 (BETA) · Morningstar-Engineering/ML10X · GitHub
