AH speeds up and slow downs (warble) on start via OB

Hi ya’ll. So I’ve got this AH mkii and I finally tried the plugin with Overbridge (which is awesome).

I’m having a weird problem though. When I play the audio from the DAW (or toggle the AH from off to on while the audio is playing), the audio gets all warbled and speeds up and slows down before snapping to the correct pitch and time. It’s kinda like a VHS tape effect, but not a happy VHS tape effect.

Has anyone ever ran into such a problem? Any help would be greatly appreciated. The Elektron staff is on vacation for a month. I’ve tried the manual, messed around in settings, tried googling, and searching here as well.

The AH is connected via USB directly to an M2 Pro Mac Mini (Ventura) running Reaper at 48kHz.

Thanks very much

I don’t have any information for you beyond what is available in the search, however it seems like there are still some stones left unturned.

Good luck and hope you can resolve it with the available resources, as it does sound like you are not the only one to notice this behavior when using AH with overbridge in a DAW.

Hey thanks for responding. I read though the post that you linked. This isn’t latency though. The audio actually speeds and pitches up, warbles a bit, cuts out, and then corrects itself… until I stop and then start the audio again. Then it does it again. The whole things lasts around 5 seconds.

I’m sending audio directly from the DAW to the AH and then back to the DAW, all though the USB which is plugged directly to the computer (no hub).

I’ve never used an Analog heat so my only suggestion is to try it with the standalone app instead of reaper and see if the behavior is still present.

The only thing that I can think of is that if your AH has the warble effect (which I believe has the behavior of tape emulation), perhaps it’s a byproduct of that being engaged.

Unfortunately, I can’t provide any decisive opinion though.

Maybe try and dime the dry mix and see if it’s still present. I assume that there’s a wet / dry ratio somewhere, or that you could create one if necessary?

You could also try it without overbridge. Elektron devices will record to a stereo track if assigned as a class compliant audio device, just like hooking up an audio interface and piping it to a track.

Arm a stereo track to record and try the AH straight to that, bypassing the OB plugin and check for results. Make sure to switch out of Overbridge mode in the device menu in order to accomplish this.

That should at least tell you if the problem is related to the AH or to OB (or as a byproduct of settings related to OB).

That’s ok, thanks for helping me think it through. It’s a mkII so no effects.

I tried with with Dry all the way (no wet) as well as disengaging the ON button, and it still happens. It doesn’t happen when I bypass the plugin from within Reaper.

I’ll try your bypass OB idea and report back.

I’ll try Ableton as well as it could be a weird Reaper setting, now that I think about it.

I feel like it could be a sync issue somewhere. It could be one of those things where it takes a week and a half to find that one cryptic hidden menu item to uncheck lol.

I’ll report back so if someone else has the same problem in the future, there’s a record.

Thanks again for your help.

Let me know how it turns out. I don’t have any other ideas at the moment but it’s possible with more information something may occur to me.

You tried monitoring from the headphone or the physical outs and it was not present there?

The problem is looking in 6 directions at once. With shit like this you really have to start by looking for the culprit and then figuring out why that component is behaving in that way. Right now it’s too vague in that we aren’t sure where to point the finger, so if you aren’t getting any warble from the audio outs or the headphones it casts suspicion towards the DAW or I guess the computer itself, or even the USB cable, you never know.

As unlikely as something may be, you never know.

Even opening and working from a new test project is usually a good measuring stick for if the problem is specific to settings or more of a global issue.

Yeah, you said this is only sending audio through OB/usb yes?

Is this on a track directly or on a fx send?

Does this happen at 96k?

if you have synced effects they may be ‘catching up’ as the clock changes. you could try having sync off but set the bpm to match. just a guess.

Sooooo, I tried it in Ableton and had no problems. Looks like a Reaper problem. My intention is to use this during a mix, and I mix in Reaper. But I haven’t exhausted trouble shooting and there might be a setting somewhere (Reaper has a ton of them). I am also going to try loading in the VST3 version. I’m working on the AU version here for the plugin.

Yeah, only through OB/USB. It’s on a track insert. It happens at 44.1 though 96k. As stated above, it is working in Ableton, so I need to dig into Reaper a bit more.

I tried finding this setting via Settings but it is not letting me turn off the sync. I tried disabling Active At Start under the sync and rebooting the AH but it resynced anyway. It’s a good idea though, I’ll look for settings in Reaper that pertain to sync and see if one of them is messing it up.

OK, so I’m new here and I’ll figure out how to not spam the thread with multiple replies lol. Thanks for everyone’s help. I’ll poke around and update when I get something interesting. I’ll mess around with it again tomorrow. I had a long day and have an early start tomorrow.

If it’s only happening in reaper after testing with ableton I would probably focus my efforts there but I can’t imagine what it is other than incompatibility with the plugin itself. I mean there could definitely be some settings in there that I’m not aware of because I don’t have any experience with reaper, but maybe some of the same issues others faced with different elektron gear will be relevant.

This person notes that sync is an issue, and they made some seemingly useful observations.

it also looks like they made a video that explores their method of multi-channel recording.

I would at least scan those for a source of potential conflicts which may ultimately be relevant to the AH as well.

Good work on troubleshooting this though.

Oh awesome! Thanks so much for your help. I’ll go though all of that for sure. Super appreciate it.

I love Reaper, but it’s a little crazy with all the options and I haven’t been on it for that long, so I’m still in the learning curve.

It’s supposed to be a super capable DAW, and I got interested in it at one point, but decided that I didn’t have the patience to learn something with that much depth at the moment and then just haven’t dipped my foot back in. Hopefully this ends up being something which you can just grift a little method out of someone else’s past labors to resolve and then just get back to recording.

Does make me wonder if Ableton sends clock continuously whereas maybe Reaper does not with whatever settings until transport start?

@Maldaisy_Jenkins Try disabling clock receive on the AH, if it doesn’t react the same then you know what the issue is.

@ shigginpit Yeah I’ve used most major DAWS except for Bitwig and Logic at this point. Reaper is definitely finicky, but with any DAW, once you crack the code on a handful of quirks things speed up. Maybe two handfuls for Reaper though lol.

@ thermionic Oh good call! I’ll mess with it.

The price is right!! That might be all the motivation necessary lol
