Aeros audio pop sound issue (makes it unusable for ambient music)

hey tried this but no luck!

I also have that issue :frowning: My Aeros Loop Station is first in my chain, so it is not related to pedals that go before it. I also have MIDI in connected to tempo sync. @BrennanSingularSound Any updates on this topic? Do you need any type of testing on our side?


+1… It s very important to fix this issue. It is not an little issue for a Looper… It s a BIG ISSUE.


+1, any updates on this would be massively appreciated


I have the same issue, in ROP mode I get a “pop” at the beginnig of the loop.
This makes ROP mode useless for soundscape players, the pop is really annoying.

I made a video with this issue:

The issue looks the same in quantized mode.

Is there any chance to fix it?


Been lurking in this thread for a while hoping for a fix. I’ve got exactly the same problem, have the Aeros bypassed on my board gathering dust because of the pops. It’d be awesome if there was some official news on the issue.


I have had the same problem when updating to 5.1.x. Going back to the previous version 4.3.x solved the problem for me, but it is not ideal. I look forward to the team solving this problem. Some information on this would be nice, it is a pretty serious error.


Hey everybody,

First off thanks for all of the feedback and reports, they have been helpful in pinning down the problem

We do not have any news to report but we are actively looking into it and it is currently our top priority to fix this issue, we intend to have improvements for the next iteration of the firmware

Thank you for your patience!


Hello all,

I am happy to inform you that it appears we have solved the major issues causing a majority of the pops and may have fixed the issue entirely

The new fixes will be part of the new 5.2.x firmware which we will be showing a sneak preview of at NAMM this week! Meaning the beta is not long away, just the new features still need tweaking and some known bugs are present.

Hi Brennan, does “Loop decay redesign” means continuous decay across seams in a loop a.k.a. Frippertronics? Thanks.

Correct! We are testing a version that has the ability to constantly decay without having to press any buttons


Thanks. Is it possible to join the beta?

Not at this time, but very soon

Thank you all for your patience


any news about 5.2.0??

It is currently in closed testing and we hope to have it ready as a beta for open testing soon, thanks for the question and your patience


I have to say that you guys at Singular sound could have stopped development by now and still have an amazing product…THANK YOU so much for continuing to make Aeros even better. Ive turned on so many of my looper friends to Aeros mostly because of the awesome support and effort you guys are putting in to this magical little box.


We fixed it :slight_smile: :tada:


It’s fixed! Amazing, thank you so much! And the other updates are awesome too. This looper is probably the best one out there now!

Edit: It now pops on the loop seams when fading to a stop, but that’s a much more chill bug to have in the short term.
