Chapter 3. Creating Your Own Sounds

TVF VELOCITY

V-Sens (TVF Envelope Velocity Sensitivity)

Use this parameter when you want velocity to affect the TVF Envelope. Higher settings will result in a greater difference between strongly and softly played notes. Negative (-) settings will invert the effect.

V-Time (TVF Envelope Time Velocity Sensitivity)

Use this parameter when you want velocity to affect the time of the TVF envelope. Higher settings will result in a greater time difference between strongly and softly played notes. Negative (-) settings will invert the effect.

V-Resonance (Resonance Velocity Sensitivity)

Use this parameter when you want velocity to affect the Resonance. Higher settings will result in a greater difference between strongly and softly played notes. Negative (-) settings will invert the effect.

TVF ENVELOPE

These parameters set the TVF envelope (the way in which the cutoff frequency will change over time).

Pan

Adjust the pan (stereo location) of the Rhythm Tone. L64 is full left, 0 is center, and 63R is full right.

Random (Random Pan Depth)

Use this parameter when you want the stereo location to change randomly each time you press a key. If you do not want the stereo location to change randomly, set this to 0.

Alternate (Alternate Pan Depth)

Use this parameter when you want the stereo location to alternate between left and right each time you press a key. Higher values will result in a greater width of change. L or R values can be set, and this will reverse the left/right order of the panning. If you want to alternate the pan position of two Rhythm Tones, set them to opposite L and R settings.

TVA VELOCITY

Specify how keyboard velocity will affect the time of the TVA envelope.

Velocity Sens (TVA Envelope Velocity Sensitivity)

Use this parameter when you want velocity to affect the TVA Envelope. Higher settings will result in a greater difference

between strongly and softly played notes. Negative (-) settings will invert the effect.

Velocity Time

(TVA Envelope Time Velocity Sensitivity)

Use this parameter when you want velocity to affect the time of the TVA envelope. Higher settings will result in a greater time difference between strongly and softly played notes.

Negative (-) settings will invert the effect.

T1–T4 (TVF Envelope Time 1–4)

Set the times over which the cutoff frequency will move from

one point to the next.

L1–L4 (TVF Envelope Level 1–4)

Set the cutoff frequency levels for each point, relative to the

basic cutoff frequency.

■Changing the Volume and Stereo Location of a Rhythm

Tone (TVA)

The TVA (Time Variant Amplifier) controls volume changes and stereo location.

TVA

Level

Adjust the basic volume of the Rhythm Tone. Use this parameter to adjust the volume balance between Rhythm Tones.

TVA ENVELOPE

These parameters make settings for the TVA envelope (changes over time in the TVA level).

T1–T4 (TVA Envelope Time 1–4)

Adjust the time over which the volume changes from one

point to the next.

L1–L3 (TVA Envelope Level 1–3)

Adjust the volume level of each point relative to the basic

TVA level.
