Transmit
When the “Parameter Change Tx Switch” is On and a parameter is
edited via DME Designer, appropriate Parameter Change data will
be transmitted as specified by the “MIDI Parameter Change Table”
and “MIDI Tx Channel” settings.
Refer to “Supplementary Information 1” for cases in which multi-
ple messages are assigned to a single parameter.
Refer to “Supplementary Information 2” for information on setting
Parameter Data values.
Supplementary Information 1
Messages Transmitted When Multiple Messages are Assigned to
the Same Parameter
The DME8i-C/DME8o-C/DME4io-C MIDI transmit messages
are specified via the “MIDI Control Change Table” and “MIDI Pa-
rameter Change Table.”
(The “MIDI Control Change Table” and “MIDI Parameter
Change Table” can be set up via DME Designer.)
Multiple messages can be assigned to a single parameter, but the
DME8i-C/DME8o-C/DME4io-C will only transmit one of the as-
signed messages.
The transmitted messages are as follows:
• If a Control Change message and a Parameter Change message
are assigned to the same parameter
→ the Control Change message will be transmitted.
• If multiple Control Change numbers are assigned to the same pa-
rameter
→ the smallest Control Change number message will be trans-
mitted.
• If multiple Parameter Change numbers are assigned to the same
parameter
→ the smallest Parameter Change number message will be trans-
mitted.
Supplementary Information 2
Setting the Parameter Change Message Parameter Data Values
The Parameter change parameter values are expressed as 32-bit in-
tegers with or without parity.
•A parity bit (positive:0, negative:1) is added above the most sig-
nificant value bit (bit 31).
• Fractional parameters will be converted according to the integer
table.
• For integers with parity, negative numbers are expressed as the
2’s complement.
