SysEx ◊ Handshake
Following the guidelines of the MIDI specifications, data is transmitted as
follows: First, the System Exclusive Header is sent. The amp will wait
200ms to look for a handshake. If no handshake is received then the amp
will transmit the first data packet. The transmission continues until all the
information has been sent. After the last packet, the End of File message is
sent. The System Exclusive device ID must be set to Omni (or the same as
the transmitting device ID) to accomplish the data transfers. NOTE: Data
values are displayed in hexadecimal with "H" for clarification.
