You can set the PCM sample rate to 88200 instead if that's what you want to downsample to. Or keep that as it is and add a DSP resampler to whatever rate you want. As long as you aren't setting the SACD PCM sample rate to 44100 and resampling UP afterwards it's ok.

 
So I have to use the resampler after all?? Anyhow, thanks for the advices!

Have you checked if TASCAM's Hi-Res Editor (freeware) is fast enough editor for you to clip a 10s (DSD256) sampe from the original file ? 

That's great, thank you for bringing our attention to this!
