Address 1: EFX TYPE
Data 1: Use the two values MSB and LSB to specify the effect type. For details
on the effect type, refer to Insertion Effect Types (p.48) and to Inser-
tion Effect List (p.156).
Address 2: EFX PARAMETER 1 (– 20)
For details on the parameters, refer to Insertion Effect Types (p.48)
and to Insertion Effect List (p.156).
Data 2: Specify the parameter value in the range of 00 – 7F (0 – 127).
Checksum: Refer to How to calculate the checksum (p.184).
Address 3: PART EFX ASSIGN
x: Part Number (In the MIDI implementation, the part number is de-
scribed as the block number. For more about the correspondence be-
tween part numbers and block numbers, refer to p.176.)
Data 3: 00 – 01
00 = BYPASS (Effect Off), 01 = EFX (Effect On)
<Example> Applying Insertion Effect 06:Distortion to Part 1
Transmit the following System Exclusive Messages in turn.
Firstly, set the effect type to 06:Distortion by transmitting EFX TYPE.

Effect Type
Secondly, sets the effect parameter Drive to 127 by transmitting EFX PARAMETER 1.
