The Vibrato Delay message cannot be sent.
2.3.20.4 TVF Cutoff Frequency
NRPN MSB = 01H
NRPN LSB = 20H
Data Entry MSB = mmH
mm : Cutoff Frequency = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the TVF Cutoff Frequency message, the reset TVF cutoff frequency
value for the tone is changed accordingly. There is no change when the value of the data entry
MSB is 40H (0).
Send
The TVF Cutoff Frequency message is sent whenever a cutoff frequency operation is performed
using the initial screen in the Synthesizer Mode.

The TVF Cutoff Frequency message is sent whenever a resonance operation is performed using
the initial screen in the Synthesizer Mode.

2.3.20.6 TVF/TVA Envelope Attack Time

NRPN MSB = 01H
NRPN LSB = 63H
Data Entry MSB = mmH
mm : TVF/TVA Envelope Attack Time = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the TVF/TVA Envelope Attack Time message, the reset TVF/TVA
envelope attack time value for the tone is changed accordingly. There is no change when the value
of the data entry MSB is 40H (0).
Send
The TVF/TVA Envelope Attack Time message is sent whenever an attack time operation is per-
formed using the initial screen in the Synthesizer Mode.

2.3.20.7 TVF/TVA Envelope Decay Time

NRPN MSB = 01H
NRPN LSB = 64H
Data Entry MSB = mmH
mm : TVF/TVA Envelope Decay Time = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the TVF/TVA Envelope Decay Time message, the reset TVF/TVA
envelope decay time value for the tone is changed accordingly.
There is no change when the value of the data entry MSB is 40H (0).
Send
The TVF/TVA Envelope Decay Time message cannot be sent.

2.3.20.8 TVF/TVA Envelope Release Time

NRPN MSB = 01H
NRPN LSB = 66H
Data Entry MSB = mmH
mm : TVF/TVA Envelope Release Time = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the TVF/TVA Envelope Release Time message, the reset TVF/TVA
envelope release time value for the tone is changed accordingly.
There is no change when the value of the data entry MSB is 40H (0).
Send
The TVF/TVA Envelope Release Time message is sent whenever whenever a release time opera-
tion is performed using the initial screen in the Synthesizer Mode.

2.3.20.9 Drawbar Control

NRPN MSB = 40H
NRPN LSB = 00H to 08H (16' to 1')
Data Entry MSB = mmH
mm : Bar Position = 00H to 7FH (0 to 8)
The following shows the relationship between the NRPN and the drawbar numbers.
MSB LSB Drawbar Number
40H 00H 16'
40H 01H 5 1/3'
40H 02H 8'
40H 03H 4'
40H 04H 2 1/3'
40H 05H 2'
40H 06H 1 3/5'
40H 07H 1 1/3'
40H 08H 1'
The following shows the drawbar position for each mm value.
mm : Bar Position
00H to 0EH 0
0FH to 1CH 1
1DH to 2AH 2
2BH to 38H 3
39H to 47H 4

While a Preset Drawbar Organ tone (Bank Number 60H) or User Drawbar Organ (Bank Number
61H) is selected on the MZ-2000, you can use Drawbar Control messages for external adjustment
of harmonic component levels.
