INTERFACING DATADISK

DATADISK CONNECTED TO A SINGLE MIDI DEVICE

Set-up of the is simplicity itself. Simply connect the MIDI
DATADISK
Out of the synthesizer, sequencer, effects processor, or other MIDI
device that is to send system exclusive data, to the MIDI In of
. To off-load data, connect the MIDI Out of to
DATADISK DATADISK
the MIDI Input of the MIDI device that will be receiving the data.
HAND-SHAKING
Although most MIDI devices that are capable of dumping data to
will only need one MIDI cable at a time when using
DATADISK
(MIDI device Out to In for a dump;
DATADISK DATADISK DATADISK
Out to MIDI device In for an up-load), there is some earlier MIDI
equipment that requires both cables to be connected for operation.
This is because the MIDI device must Handshake with .
DATADISK
When such a MIDI device is in the receive or up-load mode,
may be able to send data faster than the MIDI device is
DATADISK
able to process it. In order to give itself a chance to catch up with
the transmission, the MIDI device sends out a command to stop the
transmission (the "Handshake"), then after it has caught up, it
sends out another command to begin transmission again.
