I have a strange issue with my DN and Overbridge in Windows 10. Issues occurs in the VST or standalone application.
Audio plays fine no issues - then suddenly it pops almost like a buffer overload and for a while the sounds are slightly tuned up, almost like it is a sample with speed increased slightly… Before long the audio pops again and returns to normal.
I have managed to record this happening. I searched everything I could think of to find an answer but couldn’t find anything… Hoping you guys might be able to suggest something?
Yes, tried a few different projects and a fresh blank one. Realising it is definitely speeding up the playback, it goes out of sync with the clock in ableton also when it happens.
…yup…swedish fm and all in tune can be an issue…sometimes…
no ob needed for this to happen…but it’s rare…no corrupted project…just fm’s complex nature…
Check the sample rate your audio interface is running at and make sure it’s the same as overbridge. From the pop and the pitch change it sounds like what might happen if overbridge is running at 44.1 and your interface is running at 48 and the driver suddenly switches between the settings so that audio transmitted at 44.1 is played back at 48: it would be pitched up about a semitone and you wouldn’t have enough samples for the buffer, causing a dropout
You have no options to change the Sample Rate with OB, only the buffer size. I don’t know why (usually, it’s the first thing I do when installing a new OB version) but my Audio Interface and OB weren’t on the same buffer size so I will report if that was the case for my own issue. Thanks.
I was thinking that maybe OB expects a particular sample rate and if an audio interface is set differently (like if OB only works at 44.1, 256 sample buffers and your audio interface and DAW are working on 48, 128) there could be unexpected behaviour. I haven’t used OB in ages so this is all hand wavey, but the combination of pops and pitch changes could be caused by changing sample rate/buffer len inappropriately.
It’s a good guess. Maybe you just solved my issue. I didn’t have time lately to look at this (family vacations) but I’m hopeful this will do the trick.
I have spent some time playing with buffer sizes, making sure everything is set to the same, trying it at different values. The pop sound that it makes does sound like an overload so this was my first guess.
There is no way to change sample rate in the overbridge control panel, however there is a setting in the standalone Digitone application… There was a discrepancy with the DT set to 48kHz and my interface set to 44.1kHz… I’m hoping this will fix the issue, will report back after playing around with it today.
Yes, have done all that recommended audio optimisation stuff on the PC end. It’s a good call, I went back through and checked everything too. Honestly the PC has been running flawlessly with Ableton and any other VST I throw at it so far, I thought it would handle OB without issue. Thanks for the reply friend.
