Suddenly developed wrong drum sound

> 1. When you first installed Musician on your new machine and then

No, for the first 3 weeks of using Musician on my new laptop, all the midis would play fine without any manual adjustment. Just load and play away.

Yes, I am loading the same original midi files which played perfectly before; not the ".not" files.

Entirely different instrument like piano.
