How did this end up in unsent drafts?  Sorry for the late reply.

You can fix unbalances in your MIDI-interpreter by extending the
following from ly/midi-init.ly:

instrument-equalizer-alist  = #'(
         ("flute" . (0 . 0.7))
         ("oboe" . (0 . 0.7))
         ("clarinet" . (0 . 0.7))
         ("bassoon" . (0 . 0.6))
         ("french horn" . (0.1 . 0.7))
         ("trumpet" . (0.1 . 0.8))
         ("timpani" . (0.2 . 0.9))
         ("violin" . (0.2 . 1.0))
         ("viola" . (0.1 . 0.7))
         ("cello" . (0.2 . 0.8))
         ("contrabass" . (0.2 . 0.8))
         )

I don't know what MIDI-expander those values were intended for, to be honest.
