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).
fig.3-44.e
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.
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.
TVA ENVELOPE
These parameters make settings for the TVA envelope
(changes over time in the TVA level).
fig.3-46.e
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.
