Filter Cut Off Frequency

NRPN MSB = 01H

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 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 Attack Time

NRPN MSB = 01H

NRPN LSB = 63H

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

NRPN MSB = 01H

NRPN LSB = 64H

Data Entry MSB = mmH

mm.. Filter/AMP Envelope Decay Time = 00H to 40H to 7FH (-64 to 0 to +63)

Recognition

When the instrument receives this message, the preset Filter/AMP Envelope Decay 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 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).

RPN (Registered Parameter Numbers)

On the instrument, RPNs are defined as settings for the following parameters.

RPN Null

The MSB and LSB of an RPN specify the parameter being 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.

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.
