Transmit
When the “Parameter Change Tx Switch” is On, appropriate Parameter Change data will be transmitted when a parameter
is edited via the panel controls, as specified by the “MIDI Parameter Change table” and “MIDI Tx Channel” settings.
Refer to “Supplementary Information 1” for cases in which multiple messages are assigned to single parameter.
Refer to “Supplemental Information 2” for information on setting Parameter Data values.

Supplemental Information 1

Messages Transmitted When Multiple Messages are Assigned to the Same Parameter
The DME64N/24N MIDI transmit messages are specified via the “MIDI Control Change Table” and “MIDI Parameter
Change Table.” The “MIDI Control Change Table” and “MIDI Parameter Change Table” can be set up via the DME
Designer application.
Multiple messages can be assigned to a single parameter, but the DME64N/24N will only transmit one of the assigned
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 parameter → the smallest Control Change number
message will be transmitted.
• If multiple Parameter Change numbers are assigned to the same parameter → the smallest Parameter Change number
message will be transmitted.

Supplemental Information 2

Setting the Parameter Change Message Parameter Data Values
The Parameter change parameter values are expressed as 32-bit integers with or without parity.
• A parity bit (positive: 0, negative: 1) is added above the most significant 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.
