Instruments not catered for currently in Musescore
There are currently a number of instruments not available in Musescore. They are: -
1) Lupophone - the Baritone member of the Oboe family - becoming more common, very dark and thick sound - lowest not F2
2) Violino Piccolo - used by both Bach and Fuchs, used widely in the Baroque period, but making a modern comeback. Two variant tunings were common, tuned from B flat below Middle C in fifths, or from Middle C in firths. With four strings. Identical in shape and construction to a violin, but smaller, and with a sweeter sound - especially in the higher registers.
3) Other sizes of Guitar (Classical) - The Contrabass, the Requinto/Alto, and the Treble/Soprano. These are identical to Guitar in every way exept size and pitch, and obviously will sound different at their respective pitches than a standard Guitar (Prime) would. The Contrabass is one Octave lower than the Prime, the Requinto/Alto is one Ffth higher, and the Treble/Soprano is one full Octave Higher.
I hope therefore that these omissions can be corrected soon in Musescore, as I would love to write for these instruments. I notice you have much rarer and much more obscure instruments than these. so why not these instruments?
