In another thread, this is what I posted..

"The RealBand help system says "RealDrums with an "Ntn" in the # column of the RealDrums Picker dialog can display notation." So I picked a RealDrum that had Ntn in the # column and generated. I also have the "When generating RealTracks also generate a RealChart" box checked (I don't see anything that separates out RealTrack instruments versions drum/percussion instruments).

I get the generated wave form, but do not get a RealChart for it."

Clearly this needs fixing in RealBand.
