sebby2000 Posted January 5, 2012 Share Posted January 5, 2012 Hi all, I'm a new member because I recently buy a MMS 2011 + Logic pro 9 on the Mac App Store Meanwhile I have a little problem with my MOTU board. When I'm playing music on Logic pro or playback a mp3 song with my motu Ultralite mk3 hybrid I listen glitches on main audio output. I always listen the music but artefact are superposed on audio. Theses glitchs are random and can be present upto once by second. I tried to change the buffer size of logic but it has no effect. Anyway the problem is present playing a video on YouTube , it's not a problem with Logic. Configuration - I use Mac os x Lion server. - Ultralite is auto-powered by the mac Mini (FW 400 => FW 800 cable) I'm searching on all forum since many days and have no answer to my problem. Have you idea ? Regards Sebby2000 Quote Link to comment Share on other sites More sharing options...

triplets Posted April 29, 2012 Share Posted April 29, 2012 Did you install the latest Motu driver from their website? Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted April 29, 2012 Author Share Posted April 29, 2012 Yes I do it today, problem is the same ;( Quote Link to comment Share on other sites More sharing options...
triplets Posted April 30, 2012 Share Posted April 30, 2012 Have you tried the USB port? What about another firewire cable? Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted April 30, 2012 Author Share Posted April 30, 2012 My motu is autopowered by FireWire, I Will try with USB cable as soon as possible. Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 1, 2012 Author Share Posted May 1, 2012 Before to change my configuration from Firewire to USB, I do some additional tests changing the clock source parameter. (I Playback Apple Loop in logic Pro directly from the media navigator) Clock source : internal sample rate : 44.1/48 => glitches Clock source : SMPTE When I change the clock source to SMPTE, the AppleLoop Playback works correctly without glitches. The main problem is the logic sequencer which is completely desynchronized, my current project can playback (position of measure in transport panel is hazardous). Clock source : Built-In Input / AUDIO IPC Playback is OK Sequencer is OK What is the clock source you have to used with a Mac + MOTU + external Synth (recorded in Midi and Audio) ?

triplets Posted May 1, 2012 Share Posted May 1, 2012 The clock source should be the Motu because you're recording and monitoring thru it. Did you try a Motu reset? There's obviously something going on with the interface. Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 1, 2012 Author Share Posted May 1, 2012 When you say The clock source should be the Motu, does this mean clock source must be internal ? Quote Link to comment Share on other sites More sharing options...

Jordi Torres Posted May 2, 2012 Share Posted May 2, 2012 Motu reset, what is the procedure ? Factory Defaults Push VALUE to restore the UltraLite-mk3 hardware to its factory default settings. Push VALUE again to confirm, or turn PARAM to cancel. J. Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 3, 2012 Author Share Posted May 3, 2012 Thank's for the procedure but I don't understand why a factory default setting can solve my problem ........ Quote Link to comment Share on other sites More sharing options...
triplets Posted May 4, 2012 Share Posted May 4, 2012 Sometimes Motu interface issues were resolved with a factory reset. Normal process of troubleshooting. Quote Link to comment Share on other sites More sharing options...

sebby2000 Posted May 5, 2012 Author Share Posted May 5, 2012 Hi, I tried the factory reset, it didn't resolve my problem . Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 5, 2012 Author Share Posted May 5, 2012 HI, I tried with DC power supply instead of auto powered byFIREWIRE => problem is alway present, glitches !!! Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted May 5, 2012 Share Posted May 5, 2012 Did you ever checked if you get the same result when having it connected via USB? J. Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 5, 2012 Author Share Posted May 5, 2012 Hi jordito, Your question is good because, few minutes ago I tried the USB connection with my MAC mini and it seams the problem dissapear !! I don't understand, bad firewire cables ??????? I bought a Mac Mini 2011 6 months ago to make music instead of Windows and buy the soundcard MOTU ultralite hybrid to have the system with the less problems (MAC + FIREWIRE + LOGIC) and take my time to make music (instead of driver debugging!!) and the result is a bit disappointing because I have to switch to USB to have stability what is the real problem ?

Jordi Torres Posted May 5, 2012 Share Posted May 5, 2012 Most likely the problem lies in the FW800 to FW400 cable you're using. But don't worry about using it through USB, that should be enough for most home studio needs (i.e., recording a couple of sources at a time). If you want to use firewire no matter what, get a better cable or adapter. J. Quote Link to comment Share on other sites More sharing options...
sebby2000 Posted May 5, 2012 Author Share Posted May 5, 2012 Concerning the FireWire cable, i didn't used the cable supplied with the motu because It is FireWire 400 and not compatible with my Mac. I bought a 400 / 800 cable but don't Know the quality of it. What is the best choice if i want use firewire link ? - use motu cable plus adapter 400 / 800 - use a new 400 / 800 cable Regards Sebby Quote Link to comment Share on other sites More sharing options...
triplets Posted May 5, 2012 Share Posted May 5, 2012 I use a good fw400 cable and bought and adapter for fw800. They cost like 7 bucks or something. Quote Link to comment Share on other sites More sharing options...
Skelter Posted September 16, 2012 Share Posted September 16, 2012 Sebby2000, do not despair ... attention: The problem stems from the Mac (in my case Mac Mini 2011). Apparently, as I read in various forums looking for Mac and Logic, the new models of Mac Mini (2011) have lowered the voltage Firewire. I have the same problem with my new Track-16. I can only work well in USB connection. Either we change the computer model, or users of Mac Mini (2011) we can forget a Firewire connection powerful and efficient. Only remains for me try to connect to an external HD Motu firewire 800 which is connected to the Mac Mini previously. I guess the external HD, to be powered via AC, will have enough voltage to the Motu. Best regards.

sebby2000 Posted September 23, 2012 Author Share Posted September 23, 2012 Hi Skelter, I tried the MOTU powering according 2 ways: auto powered by Mac mini and power by AC power supply => problem is the same ! Some speak about firewire cable quality, I didn't use a "no name" but I can't guarantee it's a high quality cable. No problem with USB but not really happy if Apple sell mac mini incompatible with firewire characteristics Quote Link to comment Share on other sites More sharing options...
rafaelminari Posted May 7, 2020 Share Posted May 7, 2020 Hi guys, I'm with the same audio gltich problem when I playback at logic or any other player (youtube as well). I'm using my Motu Ultralite MK3 with a USB cable (the original one tha came with the audio interface) and the original power suply in a Macbook Pro 2015. Anybody knows what is happening? Thanks!

What operating system are you on? Did you check if there were driver updates on the Motu website? Quote Link to comment Share on other sites More sharing options...
rafaelminari Posted May 7, 2020 Share Posted May 7, 2020 I'm using OS X Mojave (10.14.6) and the most recent driver on the MOTU website (v1.6.83634 | Jan. 2, 2020). Quote Link to comment Share on other sites More sharing options...
triplets Posted May 7, 2020 Share Posted May 7, 2020 Could be USB acting up. Can you test the FW port on your mk3 into the thunderbolt port of the laptop? You would need adapters obviously. I had the old mk1 Ultralite that was only FW and never had any issues. It actually is still getting used today in the studio as an aggregate device.

rafaelminari Posted June 22, 2020 Share Posted June 22, 2020 I think the problem is solved for me. Today is fourth day without audio clipping or audio glitches. Thanks alot for the tip with the firewire cable. Quote Link to comment Share on other sites More sharing options...
