Howdy,
Re. the score for transposing instruments: you can choose to show either concert pitch (which is what you have right now) or the Instrument Transposed pitches for the conductor's score and/or the individual instrument parts. In either the Staff or Format menu, you can select to show Concert or Instrument transposed pitches.
For sound balance, it's sometimes very dependent on the particular MIDI playback device that one uses. For instance, my default playback device is an SB Audigy 2 soundcard that I have loaded with soundfonts. When I played the song, the flute sounded fine, but the saxes were really low. It may be instructive to let folks know what device you're using, so we can understand where any differences in dynamic nuances may arise with our own favorite playback device. If you're using something like the GS Wavetable, then folks can use that (it's standard on Windows computers) to get a better idea of the relative instrument balance. Or if you're not, we'll know why it sounds different
Keep up the great work! I'll be looking forward to hearing more
ttfn,
