While we're asking random questions about GPO-A... will it contain Brass Band instrumentation?
By "Brass Band," I'm referring to the British concept of brass band, which has been a steadilly growing movement in the USA. "Standard" instrumentation is:
One E flat Soprano Cornet
Four B flat Solo Cornets
Two B flat Second Cornets
Two B flat Third Cornets
One B flat Repiano Cornet
One B flat Flugelhorn
Three E flat Tenor Horns (Solo, First and Second)
Two B flat Baritones
Two B flat Euphoniums
Two B flat Tenor Trombones
One Bass Trombone
Two E flat Tubas
Two B flat Tubas
Three Percussionists -- Timpani, battery, and mallets are standard for almost all compositions.
I've experienced a lot of frustration trying to mimick the sound of Brass Band instrumentation with GPO. SOmetimes I can get close, but usually not.
A good Brass Band library would be a good thing.
