OP-Z audio issues


I have a problem with popping / clicking audio on my OP-Z.

When I am on the drum track, certain samples will a loud klick after the kick sound, when previewing or in the track - like a clipping noise, although it shouldn’t be clipping. Again, this happens on the preview and on the track in playback. Changing parameters doesn’t help. I looked at the app, to see if it’s actually clipping. But that doesn’t seem to be that case.
The clicking noise is sort of like an “sample playback stopped noise” if you know what I mean, like unclean stop of the signal.
Those drum sounds are unusable to me.

Then I have “ghost” sounds. So there are noises / clicks playing, when there’s no steps on a track.
It seems to happen, if there’s previously were steps on the track, and I then removed them. This is mostly on the end of tracks, so the last steps. These ghost sounds are like dirty echoes from an FX channel / return.

I already tried turning off and on again.

Anybody else having any audio issues?

Factory reset the opz, maybe it helps

Ok, thanks, I’ll try that.

factory samples or custom? would be awesome if you can upload a sound-recording

Are you modding the envelopes with longer decay? Shift + Green leds? Overloading the master mix?

Are you modulating Rez by mistake ?

I’m having the same problem, did the factory reset and reinstalled the firmware to no avail. The noise appears only on the headphones output, sounds clean when recording through the internal usb interface. Did you figured out a solution?

Here is a recording of what I’m referring to. https://www.dropbox.com/s/7p1o2a76xlwgu46/opz%20clicks%20and%20pops.m4a?dl=0

Resetting the OP-Z actually did the trick for me back then!


I’m experiencing the same problems as aylk. Have you found a solution?

Hi, I am experiencing the same audio problems as in your recording linked above. How did you fix this?

Ended up sending it back to TE for repair. They were very helpful and responsive, got it back in about two weeks if I remember right. Good luck.


Sadly I’m experiencing this too — OP-Z clicks after loud transient sounds, like metronome and kick drums. Only with headphones. Factory reset did not help unfortunately.

it happens because you probably have something going on in tape track*(11) and if loop1* uses synth A track(6) and next loop2 uses synth B track(6) , tape track glitches. solution for me is to use tape track more strategically when im having many different synths in one project.

this may also happen is you have a heavy delay effect in track (9,10) that applies to synth A and B when switching loops.

*by track I mean instrument on channel 6. And synth A and B are the instruments stored on track 6
*by loop i mean your sequence 1 out of 16.

I’m thinking this could be a different issue. If I mute every single track, and just play the metronome, I get this sound. Same if I mute every track and just play the kick. Video below.

master compressor is really heavy handed and can make clicks adn stuff too
have u tried turning that down?

maybe you have “punch” cranked way up in mixer parameters

thank you both for responding. the master compressor is turned all the way down. I just did a factory reset and this problem continues.

It seems quite strange (the clicking is just as loud even if the kick or metronome is turned very low).

Any advice on repairs? I bought second-hand.

than its some electrical interference. probably a micro-component damage. you can still debug digital vs. analogue audio. Try connecting with USB-C cable and stream digital audio.

Yes it works fine over USB. Thank you for the confirmation that it is probably micro-component damage.
