Arduino uno midi system exclusive

[rebwar15]

I have found this copy, then I would study midi SysEx more, and when I upload the code in my UNO, then on serial monitors only strange signs come ....
is there something wrong with UNO that does not fit this service or is there something wrong with my PC?!!!

#include <MIDI.h>

byte sysex14[] = { 0xF0, 0x43, 0x20, 0x7E, 0x4C, 0x4D, 0x20, 0x20, 0x38, 0x39, 0x37, 0x33, 0x50, 0xF7 };
byte sysex15[] = { 0xF0, 0x43, 0x20, 0x7E, 0x4C, 0x4D, 0x20, 0x20, 0x38, 0x39, 0x37, 0x33, 0x50, 0x4D, 0xF7 };
byte sysex16[] = { 0xF0, 0x43, 0x20, 0x7E, 0x4C, 0x4D, 0x20, 0x20, 0x38, 0x39, 0x37, 0x33, 0x32, 0x50, 0x4D, 0xF7 };

                    0x20, 0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, 0x28, 0x29,

On serial monitor:----
