Creating a Patch

Env Time KF (TVF Envelope Time Key Follow)

Use this setting if you want the TVA envelope times (Time 2–Time 4) to be affected by the keyboard location. Based on the TVF envelope times for the C4 key (center C), positive (+) settings will cause notes higher than C4 to have increasingly shorter times, and negative (-) settings will cause them to have increasingly longer times. Larger settings will produce greater change.

Value: -100, -90, -80, -70, -60, -50, -40, -30, -20, -10, 0, +10, +20, +30, +40, +50, +60, +70, +80, +90, +100

Env Level 0–4 (TVF Envelope Level 0–4)

Specify the TVF envelope levels (Level 0–Level 4). These settings specify how the cutoff frequency will change at each point, relative to the standard cutoff frequency (the cutoff frequency value specified in the TVF screen).

Value: 0–127

Env Time 1–4 (TVF Envelope Time 1–4) ★

Specify the TVF envelope times (Time 1–Time 4). Higher settings will lengthen the time until the next cutoff frequency level is reached. (For example, Time 2 is the time over which Level 1 will change to Level 2.)

Value: 0–127

The envelopes appearing at the lower part of the TVF settings screen graphically depict the current values of the settings. Solid lines represent the TVF envelope, while dotted lines are used for the TVA envelope. This lets you compare the TVF and TVA envelopes while you make settings.

Adjusting the Volume (TVA)

For details on the setting, refer to “How to Make the Patch Settings” (p. 42).

TVA

Patch Level

Specifies the volume of the patch.

Value: 0–127

Tone Level ★

Sets the volume of the tone. This setting is useful primarily for adjusting the volume balance between tones.

Value: 0–127

Bias

Bias causes the volume to be affected by the keyboard position. This is useful for changing volume through keyboard position (pitch) when playing acoustic instruments.

Bias Level

Adjusts the angle of the volume change that will occur in the selected Bias Direction. Larger settings will produce greater change. Negative (-) values will invert the change direction.

Value: -100, -90, -80, -70, -60, -50, -40, -30, -20, -10, 0, +10, +20, +30, +40, +50, +60, +70, +80, +90, +100
