I got the middle-gear version (39 euro/year) since it is said to manage up to 4 tracks, and I am mostly working on SATB choir scores or solo with piano accompaniment, every chord in the piano part is considered a separate track, so you quickly go over 4.... I was willing to update to the pro version (79 euros/year), but there was no way to pay the extra 40 euros. They did honor the cancellation with a full refund optio,n so I decided to explore the trial version since I had other concerns. The trial version is very limited. In particular, there is no saving, no editing, and it woudl play only 20 seconds.... I could not find any software that would perform better, so I pinched my nose and I bought the pro version. It is very cumbersome, in my opinion.
