MZ-2000 MIDI Implementation
Receive
When the MZ-2000 receives the Vibrato Delay message, the reset vibrato delay 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 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.
2.3.20.5 TVF Resonance
NRPN MSB = 01H
NRPN LSB = 21H
Data Entry MSB = mmH
mm : TVF Resonance = 00H to 40H to 7FH (-64 to 0 to +63)
Receive
When the MZ-2000 receives the TVF Resonance message, the reset TVF resonance 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 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

Receive
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.
