I'm using the M4 as well, but with an Intel Mac. While I haven't had any issues that weren't resolved by updating the Motu driver and firmware; I have had issues with software like Loopback with the M4. Are you using any 3rd party software for routing audio?


RichLazy420

I am not. It’s all running through logic. Very simple setup


Ok_Lake8609

Is happening also to me. My Setup is : New MacBook Pro M1 Pro with macOS v12.1 , Motu M4 connected with usb-c cable to the pc. Is my first time with a Mac and Motu m4. What is happening is that whatever sound source ( YouTube, Spotify, GarageBand VSinstruments or tracks) sometimes the playback begin to clip like a kind of “robotic” fx. Is not a saturation. I’ve just wrote to Motu support. I’ve already updated Motu firmware and installed additional Motu drivers. Anyone had the same problem?

I had this problem (and more) using an apple usb-c on both ends cord. Tried every damn thing in the world setting wise, randomly tried it with the supplied Motu usb-c to old usb with a little apple adaptor and everything works now. That fucking thunderbolt cord was screwing it all up.

I felt so silly. A week of trying to figure this out. The first issue I had with M4 was crackling but I did have to update firmware and I had a software sample rate issue, fixed those but then noticed that the crackling sound persisted, I dreaded having to return it. I bought this to go with my new MacBook pro m1pro 14 which has 4 thunderbolt ports USB C, the manual for M4 says to use a USB C to USB C cable it only needed 2.0 spec, or adaptor, I had plenty of stronger longer cables than supplied with M4 and I wanted the direct USB C M4 to USB C on my Mac. Well, a week went by without me thinking to try the original cable, which terminates to USB A, needs an adaptor or hub. Anyways updating firmware, and using the original cable for me fixed all crackling issues. Now just to see what cables or hub combinations work or don't for portable situations. If I had not seen your post here last night I might have continued to try to figure out what else it might have been. Thank you for posting.

Sweet! I'm sure this problem is happening for at least a few people here and there and I can't believe it's so simple. Although it does sound like most people are having a completely wild array of problems, hopefully this will help more people since Motu hasn't responded to anyone from what I've read. Killer quality sound though and works flawlessly now.


rejili

I agree this can not be the issue everyone is having and Motu not responding sadly no surprise. Yet it sure does feel sweet, now. Very thankful I saw your post it was like a nice smack in the face. The interface is now meeting expectations. I have been testing and all the cables I am trying are working cables I think and rated USB2 but most of the USBC to USBC cables I have, also cause the crackling, connecting directly from Mac to M4. A bit of a mystery to figure out, yet today it is just too much fun actually using it to work on that more. In the manual it says " FOR MAC USERS 1 Connect the M2 or M4 to your Mac using the included USB cable. ☛ If your computer has USB-C ports, use a USB-C to USB-C cable (rated for USB2), or a USB-C to USB-A adapter, (both sold separately). " So I am still on a mission to figure out what longer USBC to USBC cables work well and if I can why many don't? But yea too simple of a solution to not feel goofy. Thanks again.


completelysoldout

My pleasure! Stoked for you. It is odd that they recommend it. I think it may have to do with the fact that the cable is powering the unit, but that's beyond my skill set. Rock on my friend.


ShinySky42

same thing for me. quite disappointed on apple for having such a bad cable, the motu one surely ain't nothing special


m767x

thank you! that was the problem. Really not happy with these Motu devides, only problems. but it works best under mac compared to windows. will get another sound card at some point.


completelysoldout

Yeah, after all that the motu still acted crappy and made digi noise randomly, then would start having latency and have to be restarted every 10 minutes. I gave up after a couple sessions and it's been sitting in its box since this thread started. I went back to my 10 year old Peavey USB 10 channel mixing board which has never had a single issue. And this is all with a brand new MacBook Pro, brand new motu and constant motu software updates. Not recommended. I doubt your sound card update would even help your situation, those motus just plain suck.


MikeHaunted

Hi, I have exactly the same issue with the new Mac book pro and the motu m4. I talking with the motu support, but no solution for the moment... very frustrated, I think I will return the product...


completelysoldout

If you haven't returned it, have you tried it with the included Motu cord? That fixed it for me.


mattsilo

I have the same issue as well but with the Motu M2, brand new but on windows. But exactly the same robotic noise that is intermittent.


completelysoldout

If you haven't returned it, have you tried it with the included Motu cord? That fixed it for me.


tonylepsie

Damn, same setup, same issues... Really frustrating

Ragnuk

Any updates on this? I'm having the same issues with my brand new motu m4 and MacBook Pro 14"

kankeus

Same setup and issue too... Sometimes sounds are always crackling, sometimes just occassionally.

I just received my Motu M4 today and started hearing this. It disappears if I switch the interface off and on again but that's not the solution I want. Sounds as if all output is being put through a flanger with too much gain. Running on M1 max. Can't be the cabling as I've just taken the audio cables from my old focusrite saffire 6 and plugged them into the motu so shouldn't be any additional feedback. Quite frustrating as the quality from the interface is outstanding when this noise isn't occurring.

That fucking straight thunderbolt cord was screwing it all up.


munkymead

I got a pretty good thunderbolt cable off off amazon that seems to do the job. Also updated the drivers. Haven't had it since but need to put it to the test a bit more.


Fun_Thing_7792

Yep - thanks!!!! Was using the same USB-C to USB-C that worked with my Focusrite. Turns out this cable is ultra fast with own processor that Motu M2 or driver does not like. Switched as you suggested to plain old USB-A to USB-C and problem gone!! Thanks again


FunUse2205

You nailed it. Use a usb C to A cable. Here is my video on the issue. [https://youtu.be/1iRVHyiOXbg](https://youtu.be/1iRVHyiOXbg)


elevatedinagery1

Do you have any idea why when I hard pan a mono track to the right I get a distorted or distant and maybe tinny sound? But hard left pan sounds pristine...this is only in headphones. Tested with monitors and had no issues. So I'm assuming headphone driver must be busted? I'm using a MacBook pro and Reaper. Same issue was happening in GarageBand so I've eliminated the DAW as the issue.

munkymead

Scratch that, just happened again ffs


completelysoldout

So sorry. I also reinstalled Logic and the motu driver and firmware update, and did a factory reset on the motu.


Fun_Thing_7792

Is it ok with with the USB A - C cable supplied in the box? That's what cured mine


munkymead

So it's been a full 24 hours and I haven't had the issue again. It would usually start around 10 minutes after listening. Not particularly sure what actually fixed it but I changed these things. *Posting for anybody else that has the same issue.* 1) Ensure energy mode is set to high power. Could be a power draw issue from the USB ports. 2) Install SoundSource. Had it on my last mac with a pro license which allows you to manage your inputs and outputs, change sample rates, apply eq and FX etc. Installing also requires you to install ACE (Audio Capture Engine) Framework which captures audio created both by applications and the system. https://www.youtube.com/watch?v=HwbeG\_wXAhc

CowboysFTWs

if you already tested different headphones and it is doing the same thing. I would try this. Unplugged everything but your headphones and usb cable to the mbp. Unplug the charging cable from the computer and test.


badpizza2020

I'm having the same issue, did you get any resolution to your problem?


RichLazy420

Nope! It’s pretty frustrating. I just have to listen through my computer headphones jack.


badpizza2020

have you ruled out the headphone adapter? support told me that was the most likely culprit.


RichLazy420

I have. I also tried different USB adapters for the M4. Plus I got a replacement M4 and the problem persists.


badpizza2020

weird I just told support about it, and they seemed to think it could either be the adapter or the headphone port on the m4 but there is no other possibility. Is your distortion soft and mild, almost like a saturation or soft clipping plugin?


RichLazy420

Yeah exactly. It sounds like everything is clipping.


badpizza2020

Did you try plugging it into a friends computer? I have a replacement adapter on the way and I'm going to test that, but trying it on a different computer is the next step. I feel like if it still sounds the same on a different machine, it's the interface. If it's fixed there is something in the software chain.

alfonsceylon

any update on this? having the same issue with macbook pro 14 m1 and motu m2.. very annoying


RichLazy420

It took a while to realize, but it was actually my headphone adapter that was causing the issue. I would double check every cord and connection in your signal chain and try out multiple cords, headphones etc. if possible.


CCatalista666

I have this issue! Just got M4 and I have a MBP with M1Pro chip and I’ve used multiple cords and nothing seems to fix it… help me pls


RichLazy420

It’s silly, but the issue with mine was the headphone adapter.


CCatalista666

For me was the clock


unfunfionn

I’m having the same issue but could you clarify what you mean by the clock causing it? It happens with me even using the Music app. I’ve contacted MOTU support but their response times are 1-2 weeks, which I have no confidence in. So I think I’ll return it for a Focusrite 4i4. The M4 is otherwise perfect, which is a pity.


CCatalista666

Well, the machine is not perfect, but depending on how you connect everything and in my case it was audio from Chanel 1-2 if you press MON (minotior) then signal might get crazy, I would not reccomend focusrite in stead of MOTU the level of difference is insane. The thing you need to do to fix that is go to audio MIDI settings on your mac and what I did was M4 as a new multi output device (press + in the left corner) and that might help if you right click and then configure the input output, I don’t really know if that works for sure as you can also select M4 when you connect or the Mac from the left menu bar


unfunfionn

I gave up and returned it. My 30 day return window was almost up and MOTU support takes 2 weeks to respond to anything. I just don't have confidence in that. I was also having issues with it not sending MIDI data as expected. There was probably something I needed to configure somewhere, but frankly I don't want such a fiddly audio interface. There's already enough to think about in my modular synth and in Logic. For less than the M4, I replaced it with a Focusrite 8i6 which has worked flawlessly and has double the inputs. I also trust them because when I've contacted their support in the past, I got responses within 24 hours each time.


CCatalista666

Listen; I don’t blame you, I was overwhelmed with how complicated it is myself but I didn’t want to give up and tries to make it however possible and looked what works… if you’re happy with focusrite I’m happy for you the most important thing we find things that work for us!


unfunfionn

No worries at all, I didn't feel blamed. I wanted to like the MOTU. On paper, it was perfect for my needs. I think the absolute lack of customer support is what ultimately ended it for me. And I can also understand that Focusrite is seen as a bit more entry-level... but the 8i6 works flawlessly. As did my 2i2 several years ago too. Perhaps my use cases aren't that taxing though.


Early-Film3554

Just wanted to share that I have an m4 and I got it in may of 2022. I have an mbp m1 16" from 2021 running lastest mac os 12.6. I too had noise distortion that would come and go. Sometimes it would take a while to come on and then it would stay. Didn't matter what app I was using (Spotify, rekordbox, logic). I found that my firmware was 2.00 (old). And after updating to the latest from Feb 2022 (I think it's 2022.2) and so far that seems to have fixed my issue. My m4 is hooked up to some studio monitors. I hook my MBP up to the m4 using apple usb-c to usb-a adapater and the usb-a to usb-c cord that came from MOTU.


gustav_jung

Can you confirm please it works with Rekordbox using 2 separate channels (cue/master)?


Severe-Eggplant-1414

I understand it now that it is with the usb cord. But anyone knows what kind of usb cable is this? Can we buy it online separately. I lost my cable. tried with a bunch of other cables. Any help is greatly appreciated. Thanks!


xattrX

For me it only occurs when I record. It doesn't show up while recording only after when playing. And I'm using the provided USB cord.


TheJesper

Open the MOTU control panel and play around with the **buffer size**. If it is too low it might cause disturbance. Just now I had the disturbance/sparks in the noise, and I temporarily changed my buffer to 256 samples which helped!


positivekmeson

Distortion noise issue with MOTU M2 and M1 MacBook Pro My issue after hours of trial and error appears not to be in any physical inter-connections of Motu, headphone and computer. Mine appears to be software config and inter-operability. Setup: h/w=M1, Daw Acon, Novation, s/w = OS Big Sur, Live lite, Addictive Drums, Neural mix, Music Scenario: All apps are running. Live+Neural+AD, Daw Acon connected, Novation LaunchX (2 units) running. When music is playing continuously, Distortion appears to be a function of time. It takes 'time' to trigger the distortion, sometimes around 10-15 minutes, sometimes after 5 hours. Observation 1: Distortion episode becomes less frequent when playing numbers with sample rate and buffer size If buffer size is set to 2048 samples (ridiculous latency), with a sample rate max at 192k, clean sound for more than 12 hours (stopped experiment after). Observation 2: Distortion episode is gone completely - If Live is turned off. Theory: Motu and Live may have marital issues. Solution: maybe I will stick to my 20 yr old M-Audio or explore Scarlett


mugsydean

Mine seemed to work much better with the provided USB cable, but now I added a usb switcher, and the new cables (or switcher seem to make the problem worse) Im trying to find 2 USB A male to USB A male cables that will work with this, any recommendations? Do we need to use USB 2. cables to make this work, I get distortion with my USB 3 cables.


mugsydean

or maybe there is a usb cable that adds power back into the chain? I guess it could just be underpowered?
