    With the Mac system below, U-Phoria UMC204HD causes Logic Pro 10.7.4 to display the message "Error while trying to synchronize audio and MIDI". When this happens, the Logic song slows down, stutters, and sounds like it is breaking apart. I have tried all the troubleshooting methods that I know of in order to fix this problem, but the only thing that stops the error from occurring is to unplug U-Phoria UMC204HD and not use it at all.

    On my previous pre-M1/Monterey system (an iMac running Catalina), U-Phoria UMC204HD was a pleasure to use, so I am hoping that Behringer might be releasing a firmware update that might fix this new synchronization error. Are there any plans to do that?

    Here is the system that U-Phoria UMC204HD is not working with:
    Mac Studio
    Apple M1 Ultra
    64 GB

      NicJonesMT Hi There.
      Can you please click support at the top of the page and submit a technical support ticket.
      We need to know as much detail on your setup as possible (Sample rate, Bit Depth, USB connections ETC).

      PedroRodrigues Hi MaxSaturation, thank you for your post, please ponder that this alert appears when the sample rate of an incoming audio signal doesn't match the project's sample rate or if the sample rate fluctuates. It appears most often when using an external audio interface, an external sync device, or plug-ins.

      When using an external audio interface such as UMC204HD with Logic Pro, the sample rate for your UMC204HD should adjust automatically to match the sample rate of your project. Sometimes, however, sample rate settings might not match. Check to make sure the sample rate settings match.
      Please confirm that your UMC204HD is set up with the same sample rate than your project on you Logic Pro.
      I would also suggest checking your project’s sample rate, choose File > Project Settings > Audio.
      If your project's sample rate doesn't match your interface's sample rate, select the correct sample rate from the Sample Rate pop-up menu.
      If your project’s sample rate does match your UMC204HD’s sample rate, select a different sample rate from the Sample Rate pop-up menu, then set it back to the original sample rate.

      I would also suggest increasing the I/O buffer size, to increase the I/O buffer size in Logic Pro, choose Logic Pro > Preferences > Audio, then choose a larger size from the I/O Buffer Size pop-up menu.
      Freeze any tracks in your project that have plug-ins.
      Check sync settings if you're syncing other applications or devices to Logic Pro, or if you're syncing Logic Pro to another application or device.
      It is also important to take into o account that when syncing another application or device that can generate MIDI timecode (MTC) or MIDI clock to Logic Pro, turn off “Auto-enable external sync and Tap Tempo.” Choose File > Project Settings > Synchronization, then deselect “Auto-enable external sync and Tap Tempo.”

      When syncing Logic Pro to another application or device using MTC, do the following:

      Make sure the application or device generating MTC is not also generating MIDI clock. See the documentation for your application or device for more information.

      With your Logic Pro project open choose File> Project Settings > Synchronization, click the Audio tab, then select External or Free from the Core Audio pop-up menu.

      I would suggest testing it by first using the built-in audio on your Mac instead of the your UMC204HD and then changing it again to the UMC204HD
      Unplug your external audio interface from your Mac.
      Open Logic Pro, then choose Logic Pro > Preferences > Audio.
      Choose Built-in Output from the Output Device pop-up menu.
      Choose Built-in Microphone (or Built-in Input, depending on your computer) from the Input Device pop-up menu.
      For last follow all these steps again to re-select your UMC204HD as the main audio device.

      I hope this helps

      Thank you

      • U-Phoria UMC204HD not working with Monterey & Apple M1 Ultra
        MaxSaturation Hi Pedro,

        Thanks so much for this detailed response.

        Regarding sample rates that do not match, and I/O buffer size: Yes, I am aware of those concerns. Please let me just mention that I have been recording on DAWs for over two decades, so I am approaching this problem with some experience. Also, it is important to note that the problem did not exist when I was using exactly the same Logic file on an earlier machine and Logic version: an iMac 2019, running the latest Catalina, and Logic Pro 10.6.3.

        But now that the very same Logic file is being used on a Mac Studio M1 Ultra running Logic Pro 10.7.4, the only problem which I am seeing is when I plug in the U-Phoria UMC204HD. As soon as I do that, the synchronization error appears.

        On this Mac Studio, Logic's I/O buffer size is at the maximum, and no tracks need to be frozen (again, the file played perfectly on a much less powerful iMac, so it should be playing even better on the Mac Studio -- i.e. I should not need to freeze tracks). Also, I am not sync'ing to any other apps or devices.

        As for troubleshooting by first using the Mac's built-in headphone out, and built-in mic (with the UMC204HD disconnected): I have done that multiple times. Again, when the UMC204HD is disconnected, my Logic file works perfectly on the Mac Studio. It is only when I plug in the UMC204HD that the sync error appears.

        At this point, with so much time invested in trying to troubleshoot this issue with the UMC204HD (with no success), I think I will simply upgrade to a different interface instead.

        I do have one last question, if you don't mind. You mentioned that although the UMC204HD adjusts automatically to match the sample rate of your project, there is a way to "Check to make sure the sample rate settings match". How does one do that, since the UMC204HD does not have a driver/interface window?

        Thanks again for taking the time to respond.

    After a recent update of Windows 10 (possibly the 21H2 update), the interface is no longer working.

      cr70 Hi, I purchased a new X32 Producer. I potentially want to use all Analogue & Digital capabilities. I use Logic & MainStage for Live & Recording. For a number of years I used 16 channel Mackie on Firewire which was simple enough but now with X32 there seems to be many options and I'm confused. People are trying to help but they are not fully acquainted with up to date digital solutions Routing etc

      My Profile
      I'm a Drummer & this is the Stage setup live

      Everything Goes through X32 Live
      X32 Edit overall control
      Macbook Pro 16 GB Apple M1 Pro Monterey version 12.6

      9 Drum Mics, Bass, Guitar, Violin, Saxophone, synth, vocals and Drums
      Midi Mainstage Patches, Pads/Triggers
      Use approx 6 Triggers & 12 Pads incl Yamaha DTX Multi 12
      Roland midi Keyboard
      2 striking pads one to advance patch program forward the other reverse

      I use Mainstage to Create Patches of Sounds and Rhythms, FX, Arpeggiators etc that are then played live.
      Using Loop Back and Play Back live

      THe Use of X32 Edit to control all front of House P.A. & stage Monitors

      The CONCERN, is it possible to set up MainStage / Logic / X32 without causing duplication or Clashing
      Maybe one of the above should be assign to be the dominant one for settings effects, reverb etc

      I use Logic for Recording and for Live settings including Reverb, Volume levels, FX, EQ, Ect. I would like to use more of X32's potential

      Can you advise/help with this , best regards, Steve Cooper

      Paul_Vannatto Hi Steve, the X32 MIDI implementation can be found here:

      If you want to control other aspects of the X32 (eg. FX settings, etc.) using MIDI, you will need to use the Sysex feature. This is because the "mother tongue" of the X32 is OSC, not MIDI. With Sysex you can send OSC commands to the X32. The best and easiest way to generate these sysex strings is to use the Sysex OSC Generator, found here

    Hi Everyone.

    Im wanting to record video and livestream via my Android phone . I have the phone connected via a USB-C OTG adaptor. I can only record from Channel 1 even though I'm hearing both channels through my headphones.

    Any ideas most welcome.

    Thank you

      PedroRodrigues Hi Osca31thnak you for your post, please consider that is not a supported configuration for the UMC22, this unit must be used connected directly to a computer running Mac or Windows via USB 2.0 avoiding any USB adaptors, as stated on the manual to operate as standard. Thank you

    I have a solo act, where I try to do everything at once, using multiple instruments, and generally post stream live as well as play in front of live crowds.


    I'm looking for entry level, expandable Analog to Digital XLR & 1/4" interfaces, 8 channel or greater, that isn't extremely expensive that I can also utilize through common interfaces such as OBS Studio...I'm not sure if I need an Ableton or another type of software, but wanted to get started with some recommendations.

    (I have a 6 channel USB mixer that currently serves me well, to pick up the pro audio and send it over to OBS.

    So, I'm using two computers, one monitor, switching back and forth. One for regular use, one strictly for music production... but I don't want to use two sets of speakers, so I still want my interface to act as audio for both computers. I've tried simply splitting the USB with a Y cable, USB B to two USB A, but only one computer recognizes the interface (and I don't seem to be able to choose which computer, but as it happens it's the correct one for music production). Is there a way to do this?

      NicJonesMT Hi Tindog13.
      You could try running the UMC into a powered USB hub, and then run this into a USB splitter. I currently do this to have devices like speakers, keyboard and mouse to swap between my Work and Gaming PC.
      One thing to note, We do not normally recommend connecting to a USB hub, as these can cause connectivity issues.

      The only other option would be to unplug your UMC and connect it directly to a different PC.

    • tindog13
      tindog13 Yeah, I was thinking that might be something to try. Think I'll ask around if someone has one to borrow to try first. Thanks.

      As an update, the powered hub did not solve the problem. With the splitter cable at least one computer was recognized, but with the powered hub neither computer is recognized. So unless anyone has any other suggestions I guess I have to have a separate set of speakers for the non-production computer, powered by its internal sound card.

    I'm new here and not sure if this is the right page. Behringer support sent me here to find parts.

    looking for a pair of rack ears for Behringer FCA 1616

      Nigel67 Hi Audiolunatic. I think that support meant to send you to filling out a spares ticket which can be done by clicking on the support tab at the top of the page. A new window will open. Scroll down and click on the Spare Parts tab and submit a ticket. The FCA1616 is a legacy product, so unfortunately there may not be any left in stock to purchase. I would also try posting on the Behringer FB site to see if anyone on there has a pair for sale or may know a company that can make rack ears. You could try this company and see if they have ever made any for the FCA1616 Hope this helps

    I have just bought the Behringer U-PHORIA UMC22 Audio Interface as it is a decent price yet is stated on Behringers own website as having low Latencey. After following all instruction including those of videos on Youtube I cannot get Latency below 1000ms. I'm sure its not my computer as its is a gaming computer with a really fast processor so I can only come to the conclusion the UMC22 is just not up to the job?

    • Wishbonemusic1
      PedroRodrigues Hi Wishbonemusic1,thank you for your post, to evaluate any latency values, you will need to have in to consideration if you are using a Mac or a Windows computer because on Windows computer you will have the drivers transporting the audio from the sound card to the CPU of the computer and them from the CPU of the computer to the sound card again and from there to the speakers.
      In a case of a Mac is different because Mac uses core audio device.

      We also need to consider when addressing latency, the following:
      The computer CPU speed.
      Audio interface quality.
      The type of connection. USB/FIREWIRE.
      The compatibility driver/operating system/ DAW.
      The amount of buffering selected on the DAW, measured in samples.

      Increasing the buffering size gives the computer more time to respond to the audio, per example when you are using plug ins, this is very important but also slows the response of the all system.

      All these points can be addressed to decrease latency issues, but this scenario will also create less stability for your system.

      Latency can be proportional to:

      The number of audio channels used
      Number of Plugins used
      Sample Rate
      Bit Depth
      Amount of Memory
      Processing Power

      I would suggest to checking on the preferences on the DAW what Buffer size are you using and I would suggest using a Buffer size between 256 and 512 samples.

      I hope this clarifies this matter

      Thank you
