NotePerformer bad bass guitar note

[Wallander]

@nradisch

Anyone else getting a Db instead of a low Ab on the bass guitar? It only happens with that instrument. If I force NotePerformer to use contrabass, I get the correct pitch. If I force Dorico to use halion I also get the correct pitch. Only the low Ab causes this problem

This is a known bug in NP 4.5.0.

We will fix it for the NP 4.5.1 maintenance release.
