Wondering if anyone else has experienced this issue, or knows a workaround. Very rarely, a patch with delay will have the delay time randomly shift without touching it (resulting in the well known pitch shifting sound). This happens maybe 1% of the time, and once it starts with a patch it seems that it will continue to exhibit this behavior intermittently. And then on a few patches there seems to be some audio trapped in the buffer of the delay, and even when I navigate away and then back to it, if I turn up the delay level I will hear the same loop (even if I haven’t played anything since switching patches). If I then turn the feedback down to 0 the loop will stop, but then the delay wont work for that patch even when I turn it back up. This honestly has almost never been an actual issue for performance or recording, as it happens so rarely. However, It would be nice to know if there was a workaround, or bug fix, or just to know from UDO if they have seen this before. Thanks in advance! ---

I have exactly the same issue with the delay! Thanks for sharing your observations. Additionally, I’m quite sure that I heard the arpeggiator speed jump around on my model. It’s similar to the delay time shifting you are describing. ---

Same issue has occurred with my S6. Only happened a handful of times since I purchased mine back in March. ---

happens fairly often on both mine and a friend’s unit during sessions. changing the delay level seems to sometimes trigger it when the level should be a wet mix and not alter the delay time. I get it’s a small company, but it is disappointing UDO doesn’t chime in on threads like this where it is clear multiple people have an issue. Seems like you have to file a support ticket to get any kind of response. ---

Good news is I’ve never had a support ticket not answered, and much to my surprise, UDO actually added an entire feature (VCA gain as mod dest) to their synthesizer at my request. I love this company. ---

I’m having this same issue. Any resolution yet? ---

I also have this bug from time to time ---

Its happening nearly all the time for me ---

Anyone figured out a fix for the arpeggiator speed jumping around? I sent my unit in for repair where the circuit board containing the delay was replaced. Since then, I’m not hearing the delay bug anymore. However, that didn’t fix the issue of the arpeggiator speed and it looks like it got worse over time. ---

I updated to FW 1.6 hoping that this delay bug would disappear. But it seems to happen more frequently now. Changing wet/dry will often trigger time shifting effect, and overall the delay will randomly shift without touching the controls. I also have the rare instances where audio buffer seems to be filled with something when loading patch. Did anyone get response from UDO on this? ---

Hey, I did the same, sent the unit in to have the delay circuit board replaced. The delay behaviour is now much improved. Sadly I can also attest that arp/tempo is still unreliable and today I experienced the worst tempo changes in a long time when running arp synced to external midi clock. Division lights kept jumping back and forth. Is it the physical encoder that gets rusty, seems like it improves somewhat when you work it for a while?
