clipping sound on new iMac when Logix X is running

HI Art of sound and thanks for your input sorry If I sounded targeting my anger towards you not the case at all.

In regards to the audio inetrface argument , I dont think Audio Kontrol from native instrument is a cheaper interface at all as all reviews online give it very high rating . I have done extensive research and couldnt find one sound card that is compatatible with USB .

Can you please clarify if any of the Motu , or M Audio, or Roland sound cards working without an issue through USB on new Imacs tested and confirmed? I am asking because I would buy one if thats the case.

The only one that seems to be working is the Apogee but I personally dont want it.

thanks

Pancenter yes I bought a powered USB hub and it did not work for me , same results pops and clicks.

I cant raise the sample bufer in ableton higher than 69 , and if I do I get the clikcs and pops ... My midi audfi utility settings have to remian high in the 89000 to get it to work across the machine platforms but at that rate it distorts the sounds in Abelton .

I have to admit the driver of my sound card is buggy but again its not the case when being used on a USB 2 machine.

Organik76,

I used a Motu Ultralite Mk3 Hybrid earlier this week via its USB2 with my iMac with USB3 ports.. (and no FD) and I had no issues at all using the latest Motu drivers with Mavericks,..

However, given it also has a FW connection, I normally use that instead because of the lower overheads placed on the CPU compared to USB2/3 but I tested out the USB2 connection just to see and as i said, i have no issues...

I have to say the Audio Kontrol was a cheap'ish product... built to a low price.. using fairly cheap components... Of course, its also discontinued now... but hopefully NI will continue supporting it in the future (for a while at least) but so far the only statement from them was as folows (in case you missed it..)

Mavericks 10.9 compatibility - An issue has been found involving NI non class-compliant audio interfaces (eg. Audio 4, Audio 8, S4 MK1, Audio Kontrol 1): If such an NI audio interface is connected to a computer waking up from Sleep mode, the device will invariably produce chopped and distorted audio on both Input and Output connections or no audio at all. To resolve the issue please disconnect and reconnect the device to your computer or change a setting of the audio interface - e.g. switching the samplerate. Native Instruments is currently conducting further systematic compatibility and performance tests with the release version of Mavericks, and will provide new information on this page as it becomes available.

This is a good example however, of why I buy Motu products... because my original Motu Ultralite Mk1 is almost 9 years old now.. and it still works great with Mavericks... being fully supported in every driver / OS X update since I bought it.. The same applies to my 6 year old Ultralite Mk2 and I suspect, the same will apply with the Ultralite Mk3 Hybrid I bought recently....

They also all have a FW connection which I have found that connection to be far more stable and efficient than any of the other USB2 connected devices I have tried/tested over the years...

This is one of those cases where you really do tend to get what you pay for.... and as I have mentioned a few times in the past.. Spending $200 on an Audio/Midi interface.. and using it with a $2/3000 Mac + Software setup is much akin to buying a Ferrari and fitting $100 tires to it.. They might be tires and they may all look much the same but you won't get the same performance out of them compared to the high performance tires costing 2-3 times as much...

The Art of sound well put all valid points. I think I know what to do from here. Thanks for sharing

You are very welcome....

Cheers..

Nigel

thanks again, can you please let me know which adapter to get for Motu to convert firewire to thunderbolt ? Any specification ?

thanks

Note that this is a FW 800 adaptor.. you may still need a FW800-FW400 cable or adaptor

also note that whilst the TB-FW adaptor does support bus-power, it only supplies 7W (?) which might not be enough for some devices. A MOTU Ultralite works fine

thanks CCTM. do I understand that the apple thunderbolt to firewire adaptor enought for Motu ultralight ?

Hi

Mine works OK, but you could always use the MOTU power supply to avoid any issues at all.

CCT

thanks CCTM let me check how that goes.

Which is what I do... whenever possible..

Hi folks. Spent a few days reading these threads while I've been troubleshooting my own version of the same thing. Have a new iMac late 2013, 3tb fd, and lots of problems with audio. My Steinberg UR824 USB2 interface chokes all audio completely when it's active. When I first got the machine, I was walked through a process of a clean Mavericks install, then I loaded the steinberg driver, produced the issue, unloaded the driver, it went away. So the tech blamed the Steinberg driver, and at that time I noticed that Steinberg posted a notice about incompatibility so I figured, ok they'll update. (If I had seen this thread, I'd have returned the machine while I still could. This *****.)

Next, Steinberg did update with a "Mavericks compatible" driver, and the problem is still there, and a couple of people on their forums are reporting similar behavior.

A few oddities in my setup / notes:

1. Booting off an external drive has not worked for me. Alas.

2. I have a POD500 USB driver that is working. So my workaround for the moment is to route the Pod to the UR824 inputs, at least letting me playback through my monitors. (But what a nuisance.)

3. My iMac is spontaneously rebooting itself at least once a day with errors largely pointing at IOUSB class libraries.

4. I tried all combinations of direct to port connections, USB3 hubs, and USB2 hubs with no differences in the behaviors.

I opened another case yesterday, and the tech noted that the "sr engineer" on the first case had noted that it may be related to the fusion drive. Which gives me hope that behind the wall of impentrable secrecy at Apple, maybe they really are working on this.

But in the meantime, my $3k audio workstation can't play an .mp3.

This is the worst experience I've had with OSX and Apple hardware since I first switched in the mid 90s. Reading through this thread, at least I know I'm not entirely alone dealing with this.

Thanks

Ugh. 4 machines! Doubtless that involves a lot of re-authorization calls to plugin manufacturers and DRM'd software companies.

Just out of curiosity, one other behavior I've noticed is that USB drives are randomly disconnecting and then reconnecting during the day. We ran hardware diagnostics on the machine yesterday and found no specific hardware issues detectable, but I'm wondering if anyone has seen this too, as it would seem at least possibly to be related.

4 Machines. Wow. Do you think I should push to have it replaced? Before I do, I'm interested to hear whether the non-fusion drive solves problems for you though, so please do keep us posted.

And like you, I do appreciate the detail folks have posted here -- yourself included of course, and everyone.

Hope springs eternal, I guess. Perhaps I should have just bought a refurb'd Mac Pro after all to replace my 2006 Mac Pro, easily the most reliable, best computer I've ever owned (and still in service as a Lion Server file server with all my sample libs and such loaded on its drives).
