I don't know if it's my sound card or what but I was writing today and noticed that the synthetic Marimba Samples of Eb5 is way out! I know this is a little picky but the marimba part I was writing was using the D Eb E Natural line and it just caught my attention. Has anyone else noticed this or am I weird?
You're not going crazy. There was a bug in that instrument, and we're just about ready (finally!) to release a library maintenance update that will fix it. If you can live with the wrong pitches ther for a few more days, the solution will be available very soon.
