Making the Volume Change ([F4 (TVA)])

Press [F5 (Global)] to turn Global on and display the "✔" to the left of the function name; the same settings are applied to all Partials used in the Patch being edited. When Global is set to OFF, then only the currently selected Partial (the Partial appearing on the screen) is edited.

Press [F6 (MIDISel)] to display the "✔" to the left of the function name; You can also press a key on a connected MIDI keyboard to select the pertial.

TVA

Level (Partial Level)

Range: 0–127

Adjusts the sound volume of the entire Partial.

Pan (Partial Pan)

Range: L64–0–63R

Adjusts the pan setting for the entire Partial.

Level

Keyfollow Point

Range: A0–C8

Determines the key used for the center of the key follow effect. The two independent parameters controlled by key follow (level and envelope time) are both affected by the Key Follow Point set here.

Level (Level Keyfollow)

Range: -63– +63

Changes the volume level relative to the key follow point. Higher settings will produce more change. Positive (+) settings will increase the volume level when higher keys are pressed. Negative (-) settings will decrease the volume level.

TVA Velo (TVA Velocity)

Curve (Velocity Curve)

Range: 0–3

Selects the curve which corresponds to the velocity value and the volume level. When this is set to “1,” velocity has no effect on the volume level.

Sens (Velocity Curve Sens)

Range: -63– +63

Determines the depth of the velocity curve.

The curve effect which was set in the Velocity Curve parameter can be gained with a setting of “0” here. The effect is emphasized for positive values, and becomes weaker for negative values. When this is set to -63, velocity has no effect on the volume level.

TVA Envelope

These parameters set the characteristics of the TVA envelope,

which applies changes over time to the Tone’s Tone level

setting.

key is pressed key is released

Time Keyfollow (Envelope Time Keyfollow)

Range: -63– +63

Changes the envelope time (from Time 1 to 4) relative to the key follow point. Higher settings produce greater change. Positive (+) settings will reduce the time when higher keys are pressed. Negative (-) settings will extend time.

Time (TVA Envelope Time 1–4)

Range: 0–127

These settings determine the times over which the Tone level setting will change from one TVA envelope level to the next.
