I’m a cellist using the Aeros Loop Studio (Firmware 5.4.5) in 6x6 mode with a MIDI Maestro. I use the “Start & End” command for more flexibility.
The issue: Whenever I start a new session, I hear a very distinct “click” or “pop” sound at the loop seam (the transition point) during the first 2 or 3 cycles of the loop. After a few minutes or a few cycles, the sound usually disappears and the transitions become smooth.
Connection: Aeros is connected to a Yamaha MG10XU mixer and an Acus One for Street amp via a Palmer PAN 01 DI box.
WiFi: OFF.
What I’ve noticed:
The “click” is audible through the speakers but doesn’t seem to be recorded onto the track itself.
Since I play the cello (continuous notes), I suspect the loop point is cutting the waveform too abruptly.
I looked for the “Loop Seam Crossfade” setting in the Device menu, but I can only find “Fade In/Out” settings in seconds, which isn’t what I need.
My questions:
Is it possible to adjust the Loop Seam Crossfade (in milliseconds) in firmware 5.4.5 to smooth out the transition for continuous instruments like the cello? If so, where is this setting located?
Why does the “click” only happen during the first few cycles and then stabilize? Is there a buffer or sync calibration happening at the start?
Could the MIDI Clock from the Maestro be causing this initial “jump” at the loop point?
Any help or advice from other 6x6 users or the dev team would be greatly appreciated!
Thanks for your answer. I have the feeling that this specific MIDI command is what’s causing the click/pop :
CC41, Value 0, Channel 1 (Next Track + Record)
I’ve done some extensive ‘dry testing’ (with absolutely nothing plugged into the inputs, only the Aeros output to the amp). The ‘click/pop’ occurs even when recording total silence, so it’s definitely internal.
What’s strange is that it only happens 1 or 2 times when the unit is ‘cold’ (just after power on). Once the gear has been running for a few minutes and is ‘warmed up’, the click disappears completely, even with the CC41 command.
I haven’t had the time to record the video yet, but I will send it to you as soon as possible so you can hear the glitch. Hope this specific CC info helps!
Just a comment from an electric guitarist : the pop also occurs in my setup and I do not use midi. The pop occurs 1 time only in my case, it’s not recorded in the loop.
I get the pop on one channel infrequently. It is not specific to a MIDI command and happens randomly regardless of whether the unit is hot or cold. Because of the randomness, it is difficult to reproduce.
I know, I’ve actually mentioned it before quite a while ago. I thought maybe the updates might have fixed something.
I’d like to start using the Aeros for professional gigs now, so it’s better if I can find the source of this problem, as the pop/click is very loud.
By this weekend, I’ll have time to film a video to illustrate the issue and send it to support. You’ll be able to see if it’s the same one you’re experiencing!
I’m getting the feeling more and more that it’s a CPU overload issue causing a digital click (I’m not sure if that’s the correct technical term!). It’s as if it has too much to process.
I don’t have that looper anymore. I sold it. The audio pop started after an update four years ago—I don’t remember the exact version, but it was around version 4.0.1 The pop would get recorded in the loop, but after a few updates, it stopped recording but remained audible and quite loud. I hope for you they solve the problem!
I bought a Headrush Core pedalboard and I’m using the built-in looper—it’s a single-track looper, but the sound quality is excellent. easy & Simple to use witha midi controler aswel
Thank you for the info. I tested this on my unit and I was able to reproduce the issue using the CC:41 value 0 channel 1 command upon power up. I reported this to the dev team for investigation.
Thank you as well for the detailed testing and observations.
Today, I set everything up to film it, but of course… the clicking sound didn’t want to come !
I only managed to catch one on recording. I don’t know how to share it with this thread ?
Right now, I’m working a lot with the looper, and the click really only happens ‘cold’. After that, I can play for an hour or two without any issues!
I also found a workaround: I load a pre-saved track, switch parts, and record with the amp output turned off!
After that, everything works perfectly—I can even open a new track, change settings, and the click is completely gone!
While running all these tests and troubleshooting, I once forgot to turn off my amp before powering down the Aeros, and it made the exact same click. Could the MIDI command be causing a voltage drop or something similar? (I am using the correct power supplies).
It’s quite hard to reproduce on camera because once the machine is warmed up, you have to wait a long time!
Let’s wait and see what the devs have to say about it then. Thanks again,
The Aeros is perhaps the best loop machine on the market and has been for several years now; however, it’s quite frustrating to have to deal with issues like popping sounds, and it’s so difficult for Singular Sound’s engineers to quickly find a solution. For live performances, not being sure the equipment is working properly adds a lot of stress to the experience.I hope that an update or patch for this problem will be released sooner rather than later.
I agree. The looper is perfect for me except for this issue. I am frustrated that SS puts the burden on the user to find such an intermittent and major issue. They actually suggested that I get an ESD mat which is rediculous. I have used Boss loopers for years without a single pop or click ever.
I too am experiencing this issue. Unfortunately for me it happened at a gig and everyone jumped. I heard someone say, “WTF was that!” Not good. I’ve also noticed that the loops are not syncing properly. This wasn’t an issue for a while, then it just popped up. It happens all the time when I undo a recording and then try to record something new in its place. But sometimes it happens on a brand new track too.
once I get it on video I’m going to start my own thread. It’s really frustrating because, if I make a mistake and need to re-record a loop during a gig, I can’t rely on it. I have to clear the whole song and start over.
