Is it erroneous that I don’t see any Presets for my Vibraphone “standard library” in VI Pro? Matrices & Patches are accessible under “Download Instruments; Percussion+Co; 21D Vibraphone” …But in the Presets category, under "Download Instruments", I see “Brass” and “Woodwind” subcategories containing their respective instruments, but no "Percussion+Co" or "Mallets". (I see only my "Celeste" under the "D. Percussion; Mallets" Preset category ...which seems questionably mis-categorized, but that's something else.)
By doing a search I found a Vibraphone Preset under the “Sibelius” category (I have the most current Sibelius presets installed).
