MIDI Data Format

Since this is a relative change parameter, it specifies an increase or decrease centered at

64.

Higher values will lengthen the release which occurs after note-off.

1.2.14Attack Time

This message adjusts the EG Attack Time specified by the sound.

Control# Parameter Data Range

73 Attack Time 0...64...127

(-64...0...+63)

Since this is a relative change parameter, it specifies an increase or decrease centered at

64.

Higher values will make the attack more gradual, and lower values will make the attack

more sharp.

1.2.15Brightness

This message adjusts the low pass filter cutoff frequency specified by the sound.

Control# Parameter Data Range

74 Brightness 0...64...127

(-64...0...+63)

Since this is a relative change parameter, it specifies an increase or decrease centered at

64.

Lower values will produce a more mellow sound.

For some sounds, the effective range may be narrower than the settable range.

1.2.16Portamento Control

This message specifies the key source number for portamento (the key number from

which portamento will start). The portamento source key is specified as 0...127.

When Portamento Control is received, the currently sounding pitch will change at a speed

of Portamento Time 0 to the key of the next note-on that is received on the same channel.

Control# Parameter Data Range

84 Portamento Control 0...127

(C-2...G8)

This is received even if Rcv PORTAMENTO = OFF.

1.2.17Effect1 Depth (Reverb Send Level)

This message specifies the send level for the reverb effect.

Control# Parameter Data Range

91 Effect1 Depth 0...127

Higher values will produce a deeper reverb. The result of the value will depend on the

state of the reverb effect.

1.2.18Effect3 Depth (Chorus Send Level)

This message specifies the send level for the chorus effect.

Control# Parameter Data Range

93 Effect3 Depth 0...127

Higher values will produce more modulation and spaciousness. The result of the value

will depend on the state of the chorus effect.

1.2.19 Effect4 Depth (Variation Effect Send Level)

This message specifies the send level for the variation effect.

Control# Parameter Data Range

94 Effect4 Depth 0...127

However, this is not received if the Variation Effect parameter Variation Connection = 0

(Insertion).

1.2.20Data Increment / Decrement (for RPN)

This message increases or decreases the value of the parameter specified by RPN (see

1.2.22) in units of 1.

Control# Parameter Data Range

96 RPN Increment --

97 RPN Decrement --

The data byte is ignored.

1.2.21NRPN (Non-registered Parameter Number)

These messages are used to set parameters such as vibrato, filter, EG, or drum setup etc.

The parameter is specified by transmitting a NRPN MSB and NRPN LSB, and subse-

quently Data Entry (see 1.2.4) is used to set the value of the specified parameter.

Control# Parameter Data Range

98 NRPN LSB 0...127

99 NRPN MSB 0...127

When the Multi Part parameter Rcv NRPN = OFF, NRPN for that part will not be re-

ceived. The following NRPN messages can be received.

NRPN Data Entry*1

MSB LSB MSB LSB Parameter name and range of values

01H 08H mm -- *2 Vibrato Rate
