Hey - just tried my first. Bach Prelude XXII - a .pdf generated from a Finale ( Ok we all had to start somewhere ! ) piece that I worked on to try and make an original piece of sheet music a bit more legible and easier to play.
It uploaded, was ready in about 10 seconds and downloaded OK.
The result was indeed impressive for a "work in progress" application / add on.
1. A few bars got either dropped or mangled.
2. Some counterpoint bars - 2nd / 3rd voice rests omitted for clarity - confused proceedings.
3. Puked at the last bar.
4. Default tempo went to 120 bpm at playback, but this was easily changed. Might be asking a bit to read the tempo from the original .pdf.
I can send you the original .pdf plus the MuseScore generated one if that would be helpful.
Please let me know of "yes" - otherwise, I hope this feedback helps you refine an already excellent debut.
