In MIDI documentation, data values and addresses/sizes of Exclusive messages, etc. are 92 3E 5F expressed as hexadecimal values for each 7 bits. 9n is the Note-on status, and n is the MIDI channel number. Since 2H = 2, 3EH = 62, and The following table shows how these correspond to decimal numbers. 5FH = 95, this is a Note-on message
