Aeros - pop

Hi everyone,

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.

My setup:

  • Firmware: 5.4.5

  • Storage: Internal Memory (No SD card used).

  • Power: Original Singular Sound 9V power supply.

  • Instruments: Cello (high sustain/continuous wave).

  • 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:

  1. The “click” is audible through the speakers but doesn’t seem to be recorded onto the track itself.

  2. Since I play the cello (continuous notes), I suspect the loop point is cutting the waveform too abruptly.

  3. 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:

  1. 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?

  2. 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?

  3. 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!

Thank you for your detailed message and for reporting this.

Could you please make a short video recording of the issue you are experiencing and include the following:

  • which MIDI command you are sending from the MIDI Maestro

  • confirmation of the firmware version shown on the device in the video

    With that, I should be able to reproduce the issue on my end and report it to the dev team.

Please send the video to support@singularsound.com and include a link to this forum thread in your email.

Thank you!

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.

Hi all,

Just chiming in as another string player (viola). I’m experiencing the exact same scenario:

  • 6x6 mode used with Midi Maestro and XR12 mixer.
  • Popping noise usually occurs when switching to playback on the first recorded loop of a session.
  • The recording mode (RPO/ROP) does not seem to matter.
  • Pop is audible but not recorded.
  • The issue never seems to occur after a few loops (even if recording ambient textures with continuous sound).

Thanks The.Buffoon for starting this thread.

This problem has been going on for four years !

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’ll keep you posted regarding the video!

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!

Which looper did you choose?

Me ?

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
