Ive been using Musescore for a little while – initially the first version, and more recently the new update. No great problems, but I did have some initial problems with v.1 causing the computer to crash. No issues (so far) apart from a couple of very minor gremlins with the current version. Easy to extract parts and to transpose (as well as dealing with transposing instruments) – I needed Treble & bass recorder parts in Treble clef with C fingerings – dead easy. Reccomended – and you certainly can’t beat the price!
