Eddy67716's thoughts on what Musescore needs.
Most importantly on this list: Triangle waves synths,
Musescore should have virtual organ drawbars that you can edit and be able to save as text that will dynamically the registration of the organ.
Musescore needs a Jazz organ instrument at 888000000 with the 2 2/3 percus.
Musescore should have some more pipe organ sounds like a Cornet V solo, String celestes, An 8 foot Diapason by it's self, Better pedal and manuals sounds, a Full organ with reeds along with Diapasons, and text to change one or both staves to Swell, Great or Choir registraions.

Musescore should have sampling technology so you can record a sound at A 440 and then get it as an instrument option.
Smooth glissandos need to be smooth and not climb chromatically like they currently do (Except on instrument's where this is impossible like the piano).
Long notes on instruments that you can change the dynamics mid tone like some synths should be able to change dynamically.
Saxophone sound really needs to be redone.
