+MIDI output has been improved
+@itemize @bullet
+@item voices are kept separated, which makes the MIDI much more useful for postprocessing
+@item optimal channel distribution: identical instruments share the same channel.  This means that e.g. for a full orchestral score there are always 16 (15 plus percussion) diffently sounding instruments available, unrestricted by the number of staves or voices.
+@item dynamics are now rendered as note velocities, no longer as midi dynamics.  This improves the sound on [high end] midi renderers.
