3. USING SYSTEM EXCLUSIVE MESSAGES
I Communication between the POLY-BOOH and a computer.
I The POLY 800II can send and receive the following kinds of information via system exclusive messages. This
enables sequencer and other data exchange with a computer equipped with a MIDI interface and suitable
software.
Sending
DATA DUMP: This includes the sound data stored in the 64 programs in memory, sequencer data, settings of
parameters 85, 86, 87, and 88, and chord memory data. This is sent in response to a DATA DUMP
REQUEST.
DUMP ERROR: Sent when a check sum error occurs during reception of DATA DUMP data.
Receiving
DATA DUMP: The program data loaded to the POLY-800II. The contents of this data replace the sound
data stored in the 64 programs in memory, sequencer data, settings of parameters 85,86,
87, and 88, and chord memory data.
DATA DUMP REQUEST: A command to transmit program data. When this request is received, the POLY-800II begins
DATA DUMP transmission after a 300ms delay.
