Quattro Under Osx 10.2.1, Need to know who else is having issues. Options

[ecksfive]

In an effort to determine whether its just my Quattro thats flaking, or all Quattros in general, can anyone please post if they have had wonky issues with recording under OSX. My outputs are fine, but my inputs seem like they are getting run through a heavy distortion filter unless I turn the latency to "high". Even then, I can only record via Live, and not Peak or Amadeus, as it still comes out garbled. Also, even in Live I can only record a few loops before the quality drops out again and goes to nasty noise/distortion. I must then quit Live, and reset the Quattro from system preferences, or physically turn it on/off to get it back to normal. But then I can only record a couple more times before I must repeat.

I've heard the OSX drivers are a little sketchy, especially USB, but this still seems like a hardware issue to me...

Anyone else have similar problems?

I've had the same problem and I've emailed the Midiman tech support about. Don't worry you're Quattro is not broken. It's actually a software issue. They told me that core audio in the Mac OS 10.2 and 10.2.1 that is malfunctioning and are working with Apple to fix it.

The Quattro works fine in OS 9.2.2.

Midiman also told me that it should work fine in OS 9.2.2 and OS 10.1.5.

They are working on a fix.

Hope that helps

Thanks, that helps.. sorta
I still can't record! heh... I wish that when something says 'Built for OSX' on the box it would actually mean it.. I'm contemplating buying another (larger?) audio interface instead.. I've heard the MOTU 828's are a bit buggy driver wise too.. what is everyone else using these days under OSX?

what is everyone else using these days under OSX?

An acoustic guitar.

Hello ecksfive,
I tried several audio configs under Mac OS X running different audio sequencing hosts (reason, melodyne, live, spark, logic..) the last few months. I have to say that the best results with affordable hardware
I had with MotU's 828. I also have to recommend the Emagic emi 2/6
for certain, not so advanced applications, they supported Mac OS X also quite early, so reason/emi 2/6 was in fact the first running Mac OS X Audio System I got under my fingers. Now I switched from Powerbook to the big iBook (yes!, G3/700 MHz, 640 MB RAM) and use it with the 828 (beta OS X drivers, downloadable from MotU: Your´re right, MotU's driver aren't the best around, but this beta works very reliable although it doesen't support the digital I/Os yet). As host application I either use this fantastic melodyne by celemony or Propellerheads reason sometimes, works great with both.
I use MIDIMAN Midi Interfaces for years but I'm not a believer of their
audio interfaces because I need really good signal quality and their built in audio A/D/D/A converters aren‘t the best for me, too.
Best-

I have a Quattro here and tried it with Deck LE 3.5 in both 10.2.1 and 9.1. Had all the OS X issues you mentioned. Booted into 9.1 and it worked as advertised. I bought the Quattro because it had to Omni I/O port on it for expansion. The Omni Studio comes with the Delta 66 PCI card which will give me the best of both worlds, usb for portability and PCI for my tower. You can buy the Omni by itself if you don't need PCI.

[ecksfive]

Yeah well... only problem is I'm on a Powerbook G4 so no PCI for me.
In any case... if anyone wants to buy a Quattro, email me. I'm not so much selling it because of these issues (there will be drivers out soonish). But more for the fact that I got a new mixing console and would like to take advantage of it's 8 outputs.
