n : Voice Channel Number = 0H to FH (Ch1 to Ch16)
pm : NRPN MSB
pl : NRPN LSB
Receive
NPRN are not received when Rx.Nrpn = OFF. Though undefined NRPN can be received and
stored, subsequent data entry values following undefined NRPN messages are ignored.
Applicable parameters are set following receipt of the NRPN MSB and LSB, the data entry MSB
is received and the value is set in accordance with the data entry MSB. The data entry LSB is
ignored.
Send
An NRPN and data entry are sent whenever the parameter assigned to the NRPN is changed.
2.3.20.1 Vibrato Rate
NRPN MSB = 01H
NRPN LSB = 08H
Data Entry MSB = mmH
mm : Vibrato Rate = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the Vibrato Rate message, the reset vibrato rate value for the tone is
changed accordingly. There is no change when the value of the data entry MSB is 40H (0).
Send
The Vibrato Rate message is sent whenever a vibrato rate operation is performed.
2.3.20.2 Vibrato Depth

Data Entry MSB = mmH
mm : Vibrato Depth = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the Vibrato Depth message, the reset vibrato depth value for the tone
is changed accordingly. There is no change when the value of the data entry MSB is 40H (0).
Send
The Vibrato Depth message is sent whenever a vibrato depth operation is performed.
2.3.20.3 Vibrato Delay
NRPN MSB = 01H
NRPN LSB = 0AH
Data Entry MSB = mmH
mm : Vibrato Delay = 00H to 40H to 7FH (-64 to 0 to +63)
