VA-76 Owner’s Manual—MIDI

Control change messages

These messages control parameters such as modula- tion and pan. The function of a message is determined by its control change (e.g. ID) number.

Modulation (CC01) *— This message controls vibrato.

Volume (CC07) *— This message controls the volume of a part. When this message is received, the volume of the part receiving on that MIDI channel will change.

Expression (CC11) *— This message conveys volume changes. It can be used to add expression. The volume of a part will be affected both by Volume messages (CC07) and Expression messages (CC11). If a value of “0” is received for either of these messages, the part volume will be 0 and will not rise even if the other message is sent with a higher value.

Pan(pot) (CC10) *— This message controls the ste- reo position of a part.

General purpose controllers (CC16~19)— These are

control change messages that have no set function within the MIDI standard. On the VA-76, CC16 and CC17 allow you to control two parameters of the M- FX. CC16 is assigned to the [M-Value 1] slider, and CC17 to the [M-Value 2] slider. See also page 219 for the parameters that can be controlled. CC18 and CC19 (as well as CC16 and CC17) are also used for VariPhrase control.

Hold (1) (CC64) *— This message conveys the up/ down movements of the Damper (Sustain, Hold) pedal. When a Hold On message is received, notes will be sustained. In the case of decay-type instruments such as a piano, the sound will decay gradually until a Hold Off message is received. In the case of sustain- type instruments such as an organ, the sound will continue sustaining until a Hold Off message is received.

Sostenuto (CC 66)— The Sostenuto pedal on a piano sustains only the notes that were already sounding at the moment the pedal was pressed. The Sostenuto message conveys the movement of this pedal.

Note: This function can be assigned to the optional foot- switch (see page 191) and an optional FC-7 (see page 194).

Soft (CC67)— The Soft pedal on a piano softens the tone during the time the pedal is pressed. The Soft message conveys the movement of this pedal. When Soft On is received, the cutoff frequency will be low- ered, causing a softer sound. When Soft Off is received, the previous sound will return.

Note: This function can be assigned to the optional foot- switch (see page 191) and an optional FC-7 (see page 194).

Reverb Send Level (CC91)— This message adds a

Reverb effect to the part.

Chorus Send Level (CC93)— This message adds a

Chorus effect to the part.

Delay Send Level (CC94) — This message adds a Delay effect to the part. Delay is not available for the Drums (ADrums and M.Drums) parts, nor for the VariPhrase/Audio In parts (VA-7).

Portamento (CC65), Portamento Time (CC05), Por-

tamento Control (CC84)— See page 89 for details. When a Portamento message is received, the Porta- mento effect will be turned on or off. Portamento Time controls the speed of the pitch change. Porta- mento Control specifies the source note number (the previously played note).

RPN LSB, MSB (CC100/101) *, Data Entry (CC06/

38)*— Since the function of RPN (Registered Param- eter Number) messages is defined in the MIDI specifi- cation, this message can be used between devices of different types. The RPN MSB and LSB messages specify the parameter which is to be modified. Data Entry messages can be used to modify the value of that parameter. RPN can be used to adjust Pitch Bend Sen- sitivity, Master Coarse Tune, and Master Fine Tune. Note: The values modified using RPN messages will not be initialized even if Program Change messages etc. are received to select other sounds.

NRPN LSB, MSB (CC98/99), Data Entry (CC06/

38)— NRPN (Non-registered Parameter Number) messages can be used to modify the values of sound parameters unique to a particular device. The NRPN MSB and LSB messages specify the parameter which is to be modified, and then Data Entry messages can be used to modify the value of that parameter.

Since the GS format defines the function of several NRPN messages, GS compatible application programs can use NRPN messages to modify sound data param- eters for Vibrato, Cutoff Frequency, Resonance, and Envelope values.

Note: The values modified using NRPN messages will not be initialized even if program change messages etc. are received to select other sounds.

Note: With the factory settings, the VA-76 will ignore NRPN messages. After a GS Reset message is received, NRPN messages will be received. You can also manually turn on Rx NRPN (NRPN Receive Switch), so that NRPN messages will be received.

Aftertouch (Channel Pressure only *) — Aftertouch is a message that conveys the pressure applied to the keyboard after playing a note, so that this information can be used to control various aspects of the sound. There are two types of Aftertouch message: Poly- phonic Key Pressure which is transmitted separately for each note, and Channel Aftertouch which is trans- mitted as one value that affects all notes on the speci- fied MIDI channel.

All Sounds Off— This message turns off all currently- sounding notes.
