Very difficult to use drumsets/percussion staves about musescore HOT 2 OPEN

There are changes being designed for percussion, but I don't know any details, so I'll leave it to others to consider how much of this might still be relevant to the new designs. However, there are also some points of confusion here with respect to the current design that I can address. Also, it is much better to file separate issues for separate problems so they can be tracked individually. I suspect this issue isn't really actionable as is. But I will try to summarize the separate issues being raised here and comment on them briefly:

1. The key signature issue is real and I think is also being tracked as #14714 which is still open with some activity, although that issue also references #14702 which is marked as resolved, so I'm not really sure of the current status
2. "Percussion" should definitely be listed among "Common" instruments; that seems a trivial fix.
3. It is true the "Percussion 1" and "Percussion 2" instruments in the Concert Band template have different drumset definitions than the Percussion instrument available to add from the main instruments dialog. So that too is a real and separate issue that would have a trivial fix. Note that while many pitches are the same between these, it looks like some pitches were defined in one but not the other, and some namings are different. But anyhow, when the new system for percussion definitions is created, we should be sure to update both the default Percussion instrument and the templates that use it.
4. I think you (@wizofaus ) may have overlooked the fact that MIDI pitch 59 is defined and works as expected in the default Percussion instrument - it is simply mislabeled as "Ride Cymbal 2". But it behaves in all other respects just like it does in the concert band template
5. The way to know which pitches are available for which notes is to consult the General MIDI standard, looking at the "orchestral" kit which is (or should be, anyhow) used for these staves.
6. Tam-tam is indeed missing from GM, but hopefully the new system will allow percussion instruments to assign Muse Sounds to individual notes instead of being limited to pitches within a soundfont (GM or otherwise).

It's been a conscious choice to keep that percussion instrument a bit buried because we want to do some major work on this method of writing.

Tam-tam in MSBasic references the Standard Kit "China Cymbal" (totally different instrument, but it is what it is) so the reason it doesn't translate to the percussion instrument is because the percussion instrument uses the Orchestra Kit.

This is also likely the source of confusion of how "Ride Cymbal 2" got mis-labeled (that note references Ride Cymbal 2 in the Standard Kit). Definitely need to correct that.

On a totally subjective note:
I'll be the first to cry about GM Percussion, from my perspective it is just wild that something so ill-concieved is the industry standard.
