Cello is: VSL Cello from Solo Strings Full.
Reger- Suite 2 - part 1 - Prelude [Largo]
Reger- Suite 2 - part 2 - Gavotte[Allegretto] - humorous piece!
Still 2 parts to go. Rather complicated getting a decent recording. It is going too far explaining it all, but when you insist... On my website [under Windows ] there is another piece for cello solo: Stiastny - Etude, a musical not so interesting piece, merely written for study purposes, I think.
Have fun and enjoy the music,
