Accordion/Bandoneon and French Horn overlap when played together

[frog8412]

Describe the bug
Accordion/Bandoneon are very close to French Horn which makes them overlap

Offending MIDI file
Pretty much every MIDI that has them playing together, but I'll link 2 MIDIs

Expected behavior
Accordion+Bandoneon/French Horn should be in different positions, or alternate their positions if both instruments are displayed

This should be an easy fix. I'll get on it!
