 MIDI output has been improved
 @itemize @bullet
-@item voices are kept separated, which makes the MIDI much more useful for postprocessing
+@item voices are kept separated, which makes the MIDI file 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.
+@item @code{\set Score.midiChannelMapping = #'staff} assigns one MIDI channel per staff, previously the default behavior.  This setting is required if you want instrument changes to create MIDI program changes on a single MIDI channel.
