Sigh.......
You know, most likely Samuel's DLS is being played back by the MS synth, anyway, so you really can't say it sounds better than the MS synth.
Whenever you're talking about the quality of a DirectMusic synth, such as the MS synth, the synth's quality can only be as good as the instrument samples in the DLS its using.
Which is why the MS synth can sound totally different, depending on the DLS loaded.
