DATA SAVE AND LOAD
To save the data stored in the RAM of the mainframe on an
external device or to load the external data onto the RAM of the
mainframe, use the exclusive MIDI message.
The following explains how to transmit and receive the data.
CAUTION
When the data load is executed, all the data stored in the
mainframe will be erased,
•Using the MC500mk2 (sequencer)
HOW TO SAVE THE DATA
The TD-7 transfers the stored data to the external MIDI instrument.
Make connections between [MIDI OUT] of the transmitter (TD-7)
and [MIDI IN] of the receiver (MC500mk2) as shown below.
