Thank you for r1723
Well, I've been anxiously waiting for this new prerelease, checking often in the last 2 weeks...
The good news: Playback of ties now works.
Not so good news: When I read a MIDI file, it still did not seem to set the instruments properly, so all of them seems to be set to some kind of piano-like sound. This is with the use of SF2.
Bad news: Previously I found a workaround to the instruments problem (documented in previous topics). Unfortunately, now the workarounds won't work either.
So, one step forward, one step backwards... My hope was to use MuseScore to read one of my compositions (through MIDI, since Sibelius can't generate MusicXML) and then generate a WAV file. It is still not working in r1723... (Of course, not willing to wait for so long, I have already downloaded other open source software, a VSTi host and a VSTi client that could use SoundFonts2, to do exactly the same thing. But it'd still be nice to see MuseScore able to do this.)
