Filter/AMP Envelope Release Time
NRPN MSB = 01H
NRPN LSB = 66H
Data Entry MSB = mmH
mm.. Filter/AMP Envelope Release Time = 00H to 40H
to 7FH (-64 to 0 to +63)
Recognition
When the instrument receives this message, the preset
Filter/AMP Envelope Release Time value for the tone is
changed to the value that corresponds to the data entry
MSB of the received message. There is no change when
the value of the data entry MSB is 40H(0).

NRPN LSB = 20H
Data Entry MSB = mmH
mm .. Cut Off Frequency = 00H to 40H to 7FH (-64 to 0 to
+63)
Recognition
When the instrument receives this message, the preset
Filter Cut off Frequency value for the tone is changed to
the value that corresponds to the data entry MSB of the
received message. There is no change when the value of
the data entry MSB is 40H(0).
Filter Resonance
NRPN MSB = 01H
NRPN LSB = 21H
Data Entry MSB = mmH
mm.. Filter Resonance= 00H to 40H to 7FH (-64 to 0 to
+63)
Recognition
When the instrument receives this message, the preset
Filter Resonance value for the tone is changed to the val-
ue that corresponds to the data entry MSB of the received
message. There is no change when the value of the data
entry MSB is 40H(0).
Filter/AMP Envelope Attack Time

Data Entry MSB = mmH
mm.. Filter/AMP Envelope Attack Time = 00H to 40H
to 7FH (-64 to 0 to +63)
Recognition
When the instrument receives this message, the preset
Filter/AMP Envelope Attack Time value for the tone is
changed to the value that corresponds to the data entry
MSB of the received message. There is no change when
the value of the data entry MSB is 40H(0).
Filter/AMP Envelope Decay Time

The MSB and LSB of an RPN specify the parameter be-
ing controlled, while the specified parameter’s value is
set in accordance with the MSB of the subsequent data
entry.
See “Pitch Bend Sensitivity” through “RPN Null” for the
data entry MSB value range and other details.

RPN (Registered Parameter Numbers)
On the instrument, RPNs are defined as settings for the fol-
lowing parameters.
NRPN MSB NRPN LSB Parameter
00H 00H Pitch Bend Sensitivity
00H 01H Master Fine Tuning
00H 02H Master Coarse Tuning
7FH 7FH RPN Null
n....... Voice Channel Number = 0H to FH (Ch1 to Ch16)
qm ... MSB of RPN
ql ..... LSB of RPN
Recognition
• RPN messages not defined by the instrument can also
be received, but subsequent data entry values after un-
defined RPN messages are ignored.
• After the MSB and LSB of an RPN are received and the
applicable control parameters settings are made, the
value is set by receipt of the MSB of the subsequent
data entry. The data entry LSB is ignored.
Send
An RPN is sent whenever an operation that changes the
parameter assigned to the RPN is performed.
