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 performed 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 operation is performed using the initial screen in the Synthesizer Mode.

2.3.20.9 Drawbar ControlNRPN MSB = 40HNRPN LSB = 00H to 08H (16' to 1')

Data Entry MSB = mmH
