In the following section, SYS_HEAD refers to a valid System Exclusive header. The System Exclusive header
starts with the System Exclusive status byte, and includes all bytes through the DigiTech device type. F7(h) is the
System Exclusive 'Message End' byte. All SysEx numbers in the format definition of each procedure are given as
hexadecimal values, along with this symbol (h) for clarification. Binary numbers are identified with this symbol
(b).
