When a key is pressed partially, its MIDI note number is displayed dimly in
hexadecimal. The MIDI note numbers range from $24 (decimal 36) for the
lowest key to $60 (decimal 96) for the highest key. Pressing the key fully
should make the display brighten but otherwise not change. If the diagnostic
detects an error (lower contact made but not the upper contact for example),
some or all of the LEDs will blink. When the key is pressed hard enough to
activate the pressure sensor, the note number display is replaced by the
pressure value display.
To exit the LED-based diagnostic, power should be turned off then back on.
