Hi Steve,

I have used the -b flags and still get problems with the audio when using CoreAudio. It may be due to the MBox drivers, as they do give problems every now and then.

The MBox and CoreAudio works fine with other applications such as MacCSound and when running CSound from the terminal. So not too sure what is different about the audio setup in blue. I have tried changing the buffer sizes and this does not correct it either.

Hi Gary,

If you're running the CSD itself with Csound directly and it's
distorting, then I would imagine it being an issue with buffer size.
Are you using -b and -B flags?  I don't have a Mac to test on, but
perhaps someone with a Mac may be able to help here. To use the MBox,
you may need to change what device is used.  With PortAudio, you
should be able to set it by using a number like dac1, dac2, etc.  With
CoreAudio, I'm not quite sure what the settings would be. Have you
tried the CoreAudio driver with Csound?
