Where do you change the sample rate (FF settings or Logic)? Do you have other devices connected digitally to the UFX?

Hi Jeff,

First of all thanks for your quick reply, Chapeau! ;-)

No other digital devices connected. Yes I do change sample rates within in Logic however I tried also to change them in "Fireface USB settings".

Before I was using Metric Halo 2882 & ULN-2 and never experienced these issues.

I have even cleaned my hard disk (format) and re-installed all OS, drivers and software.

Current installed:

OSX 10.6.7
Fireface USB settings 1.50
Firmware v342
Totalmix 0.93

Have you tried higher latency settings? Don't think you need very low latency settings for most of your work, do you?

Hallo Daniel,

Does it happen with both USB and Firewire?

I have not checked with Firewire yet, will download drivers and see what the result will be however I want to emphasize that I would like to run my unit in USB mode.

Thanks for your suggestion, will revert back to you as soon as I have the results available.

Cheers,

Gaston
