It sounds like what I linked to does the same. I just tested it out finally and the noise gate isn't doing it, it's just the DSP bypass, so I will try this out. Thanks. In case anyone who knows sees before I purchase/try one though: does the M5 use an isolation transformer? That's one rationale for me substituting the ground loop isolator for it.

Oh I missed that! Hmm. Will have to see if turning the gate off and keeping DSP on still removes noise. I wish I could just test a noise gate but I don't have one on me. If it's not the noise gate ... I posted a more detailed description of the overall problem on a Facebook forum and someone (who's spent a lot of time looking into my setup) thinks it might be that the Line 6 uses an isolation transformer. Could it be possible? Does it use one? If so, it seems like this could solve my issues, outputted from my audio interface (interface is acting like a pedal). https://www.amazon.com/RadioShack-System-Isolator-Electric-reducer/dp/B002YGM5D8

Thanks for your input. It manages to remove the noise with DSP Bypass mode but not True Bypass mode, so I reckon it's the DSP bypass only. I can't find any information about that anywhere. I can't see a noise gate in the setup. And yeah, I'm not using the dedicated noise gate effect (under Distortion, I think). I want to get a really small, really cheap pedal to do what the DSP Bypass mode is doing. I don't want to get another Line 6 M5, just because I don't see the point in getting something with so many features that I don't really need. For example, maybe the Mooer Lofi Machine would do the same noise removal as the M5 if always on with dry output only? To know this for sure before I buy one I'd need to know what DSP Bypass mode is.

I saw the sticky, saying that response takes a while because the team works through it, so to clarify my question: all I want to know is what the DSP signal chain is, so I can isolate what's reducing the noise. Or even just an internal circuit diagram that I could show to someone who could tell me. Thanks. I'm hoping to get my board complete for the new year, and this is an important stage.

Hi all, My Behringer UM2 interface is causing oscillating noise when running a Linux jack server. This noise gets eliminated by my M5 if I place the M5 between the interface and the amp. My question is, what does the DSP bypass mode have the signal run through? Is it just a buffer, or a buffer with ad-da signal conversion, or otherwise? I need to get a small pedal to fill the M5's noise removal role, but I don't know what I need to look for. Some other brands of pedals aren't this amazing at removing the computer noise. Thanks, Paul P.S. the M5 is awesome. I use it with an an EHX 8-Step to great effect.
