Also, make sure that the Realtek chip does native 44.1... I feed my MOTU card from the SPDIF output of a Creative Audigy* and I had to change my workflow to 48k because the Audigy turned out to "fake" 44.1 by constant upsampling/downsampling around its fixed-48k DSP.
* because the FireWire connection is so fragile and the damn MOTU freezes all the time Andras On Fri, Nov 11, 2011 at 04:38, Ingo <i...@miamiwave.com> wrote: > I think if you are using a mixed patch with osc and samples only the > samples > would play correctly and any osc~ might get detuned.
