=> The EMAX will transmit and receive data at one of two speeds:
=> --31.25 Kbaud (asynchronous, MIDI or RS-422).
=> --500.0 Kbaud (synchronous, RS-422 only, odd parity).
=> The EMAX powers up at 31.25 Kbaud.
=> Numbers in parenthesis () decimal, all others hex.

=>EMAX then switches internally to 500 kbaud.
=>EMAX waits for receive to send ACK (see MMA exclusives) at 500khz:
=>if no ACK comes within the timeout period, (programmable by using
exclusive #21) EMAX displays error and aborts.
=>EMAX starts high speed transfer by sending MMA-type data packet at 500 kbaud:
=>Sound data in the data packet is sent as 12 bit SIGNED linear data.
=>Data packet (see MMA Data Packet) contains 120 bytes packed like this:
byte 0: bbaaaaaa aaaaaa = 6 ls bits of data word 0
byte 1: ccccbbbb bbbbbb = 6 ms bits of data word 0
byte 2: ddddddcc cccccc = 6 ls bits of data word 1
dddddd = 6 ms bits of data word 1
byte 3: ffeeeeee eeeeee = 6 ls bits of data word 2
--etc- byte 119: zzzzzzyy zzzzzz = 6 ms bits of data word 79
=>Note that bit 7 is used in these packets, unlike standard MMA format.
=>EMAX then waits for an ACK, as per MMA protocol:
=>if no response comes within a few seconds, EMAX sends CANCEL, aborts.
=>if NAK or transmission error, EMAX retransmits packet. EMAX will try
re-sending 5 times before giving up and sending CANCEL.
=>if CANCEL, EMAX displays "Cancelled by Receiver" and aborts.
=>if WAIT, EMAX resets its timeout counter (a few seconds). If receiver
needs more time, it must keep sending WAITs.
=>if ACK, EMAX increments packet number and transmits next packet.
=>Maximum packet number is 127, as per MMA protocol. Packet numbers
wraparound and continue from 0 after that.
=>Receiver must handshake the last packet (respond with ACK).
=>After completion of transfer, EMAX automatically switches back to 31.25 kbaud.
=>The "length" in the header refers to # of 12-bit data words, (80 per
packet) not to the actual number of bytes in the packet, which is 120.
=>If key and level refer to a null voice, EMAX sets length=0 and does no high
speed transfer at all.
=>EMAX will only do this command upon receiving a request (exclusive #07).
=>Uses current preset.
