OK, it works fine now. Probably the problem was that I was using an old MacCsound file where the -b option was too low and caused the distortion. These options are only visible with a text editor like Smultron but not with qutecsound - which I am using currently. I can't test it now with the Motu but will try tomorrow.
Anyway now it's working fine!
Thanks Victor!
Luis

Is there anyone using csound with live input on a Mac? I have been using live output without any problems with the default portaudio device. But I can't figure why live input should be a problem. I tryed the built-in device and the motu 828 and both give a terrible sound.
