Interesting - that's good to know... I'll still do some testing to make sure that everything's working right!
It can be very difficult to find a good soundfont. If you want to have the best possible sound, you will probably need to use Logic X or a different app to use a commercial piano sound plugin. SeeMusic will never be able to provide that level of MIDI Synth sound inside the app - the MIDI Synth in the app is a convenient, basic option.
Dear Peter, I updated on 1.14 some minutes ago and now it works. But the insert grand-piano sounds better than the Fazioli Grand.
The email is on the way. Your piano sound is quite different from what I find in your app. What do you use?
