What is Device ID
According to the explanation on page 58 of this manual, Exclusive data is not differentiated by channel.
However, this would mean that in a complex MIDI system that contained two or more SPD-20s, it
would not be possible to transmit Exclusive data to only a specific SPD-20. To get around this problem,
each SPD-20 has its own Device ID number (116) on which it transmits and receives Exclusive data.
Exclusive data can be received only when the Device ID number of the receiving device matches the
Device ID number of the transmitting device.
In the SPD-20, the Basic Channel number is also used as the Device ID number.
In some devices, the MIDI channel number and the Device ID number can be set independently, and
will not necessarily be the same. When transferring Bulk data to another device, refer to the operation
manual for that device.
If you are using a sequencer to control two or more SPD-20s, you can set each unit to a different
Device ID so that select data can be sent to each unit. But remember that the Basic Channel numbers
will also be different.
