Appendix 4SysEx E 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
handshake messages the amp will respond to are:
