control. Each speci fi c command consists of four bytes (a string of four hexadecimal numerals).
Each SysEx message you send can contain as many of these speci fi c commands as you want.
See MSB and LSB on page -4 for an explanation of how to use MSB and LSB to send values in the
range from -128 to 255.
