Incorrect playback of Bagpiping Embellishments and Incorrect tuning.

Just before we start this off, I am the Pipe Sergeant of my Pipes and Drums band and have been playing the Great Highland Bagpipes for over 6 years.

I used Musescore as a program to allow me to compose and arrange music for other instruments, as it is my hobby. I've recently taken on a project to compose music for the GHBs and a generic concert band. But, recently, I have come across a problem.

First, the bagpipes tune incorrectly. Due to not being able to play a C (preventing them to tune from C), they tune from A. Depending on the scenario, the bagpiper either tune at A = 466hz (Bb) when playing with other instruments, or A = 475hz (around Bb-B) when playing solo or in a band setting. Because of the inaccuracies in tuning, it has been extremely difficult to actually compose music properly for the bagpipes. On top of this, it gives a lot of composers the false notion that GHBs (which is what I assume the "Bagpipe" instrument in Musescore is referring to) tune to C = Bb. Second, the embellishments are played drawn out like traditionally played in other instruments. Embellishments are done extremely quickly, almost as if a blip or tap. If you would like to hear how the embellishments are supposed to sound, search up some Bagpiping music.
