hey tried this but no luck!
I also have that issue 
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?

Hi!
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.

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

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.

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.
