VA-76 Owner’s ManualMIDI

36 being used and sent to the MIDI OUT port. This, of course, depends on the Tone you assign to the Upper1 part.

In Absolute mode, however, the MIDI note number sent to the MIDI OUT port will be the one assigned to the key you press (e.g. note number 60). The advan- tage of Absolute is that you can play a bass line using the VA-76’s Upper1 part and double it with a trumpet of an external instrument.

PartSwtc

The Part Switch parameter allows you determine what happens when you mute a part (see “Muting parts” on page 114). One thing you know will happen is that the part in question no longer sounds when you play on the keyboard – even though its field on the KEY- BOARD MODE page (accessible via the [OTHER] button) is displayed in white, or even though the Arranger is playing. What you do not see, however, is whether a muted part still sends MIDI data. PartSwtc allows you to specify whether or not a muted part should go on sending MIDI messages:

Int— A muted part can no longer be played via the VA-76’s keyboard or Arranger but continues to send MIDI messages to MIDI OUT.

Int+Mid— A muted part can no longer be played via the VA-76’s keyboard or Arranger and no longer sends MIDI messages.

Selecting Int and muting a part thus has the same effect as selecting Local Off (see page 201). Choose whichever is more convenient in a given situation: part mute can be saved to a User Program, while Local and Part Switch can only be saved to a MIDI Set.

Rx Velocity, Tx Velocity

Your VA-76 is equipped with a velocity-sensitive key- board and a tone generator capable of responding to velocity messages. Velocity messages are an important element for musical expression because the way you strike a key results in a loud/bright or soft/round note, telling the listener something about your feelings.

In some cases, however, it may be wiser not to convey the velocity aspect of music making to emulate instru- ments that are not velocity sensitive (such as organs, for example). The VA-76 allows you to activate or deactivate the transmission and/or reception of veloc- ity messages. Use the associated [ON/OFF] fields to switch the reception (RX) or transmission (TX) of velocity messages on or off.

If you select [OFF], you have to tell your VA-76 which velocity value to use instead of the continuous flux normally received (in this case, the word receive applies to both incoming MIDI data and the messages received from the VA-76’s keyboard). That is what Rx Velocity and Tx Velocity are for. The value you set will

be used for all notes received via MIDI IN (RX) or sent to MIDI OUT (TX) – but only when the correspond- ing velocity filter is set to [OFF].

SoftThru for Local

This function actually overrides the MIDI specifica- tions, according to which the MIDI OUTput of an instrument only sends messages generated on the instrument itself (e.g. your VA-76). When you set Soft Thru to On, all notes received on the NTA channel beyond the NTA’s High and Low Limits are re-trans- mitted to the MIDI OUTput. Use the Soft Thru fea- ture for a digital piano or other keyboard instrument without split function.

When you set Soft Thru to On, The VA-76 sends a Local message (CC122) with a value “0” to the digital piano, so that the piano’s sound source no longer responds to the notes you play on its keyboard. Seeing that the VA-76 echoes back all notes that are not used to trigger the Arranger, you hear what you play on the piano – except in the zone set apart for the Arranger. (This requires that you also connect the VA-76’s MIDI OUTput to the digital piano’s MIDI INput.)

When you set Soft Thru back to Off, the VA-76 sends a Local message with a value “127”, thereby switching the piano’s Local function back on.
