Creating a Rhythm Set

RHYTHM KEY TVA (Making the Volume Change)

The TVA (Time Variant Amplifier) controls the Rhythm Tone’s volume changes and stereo positioning.

VEL CURVE
(TVF cutoff velocity curve)

FIXED, 1–7

This selects one of seven curves that determine how keyboard playing dynamics (veloc-
ity) influence the Rhythm Tone’s cutoff frequency. When V-Curve is set to “FIXED,” the
cutoff frequency remains unchanged regardless of how hard or soft the keys are played.

VEL SENS
(TVF cutoff velocity sensitivity)

-63–+63

This sets the amount of change to the Cutoff setting to be applied as a result of changes
in playing velocity. With higher settings, there is a greater amount of change between
softly and strongly played notes. Negative (-) settings reverse the direction of change.

TVF ENVELOPE

These parameters determine the amount of filter enveloping—changes to your original
cutoff frequency setting that occur over time—the effect of velocity on the TVF envelope,
and the basic characteristics of the TVF envelope itself.

ENV DEPTH
(TVF envelope depth)

-63–+63

This adjusts the amount of filter enveloping. Higher settings produce more change. Neg-
ative (-) values invert the effect of the TVF envelope.

ENV VEL CURVE
(TVF envelope velocity curve)

FIXED, 1–7

This selects one of seven velocity curves that determine how velocity will affect the depth
of the TVF Envelope. The selected curve is displayed graphically to the right of its value.
When set to “FIXED,” the TVF envelope depth remains unchanged, regardless of how
hard or soft you play.

ENV VEL SENS
(TVF envelope velocity
sensitivity)

-63–+63

Use this parameter when you want keyboard playing dynamics (velocity) to affect the depth
of the TVF Envelope. With higher settings, there is a greater difference in the TVF envelope
depth when you play softly or hard. Negative (-) settings reverse the direction of change.

ENV T1 SENS
(TVF envelope time 1 velocity
sensitivity)

-63–+63

Use this parameter when you want keyboard playing dynamics (velocity) to affect T1
(Time 1) of the TVF envelope. With higher settings, the T1 value will change more signif-
icantly depending on whether you play softly or with greater force. With positive (+) set-
tings, greater keyboard velocity will reduce the T1 setting. With negative (-) settings,
greater keyboard velocity will increase the T1 setting. Use this parameter when you want
velocity to affect T1 (time) of the TVF envelope. For higher settings, there will be a greater
difference between softly and strongly played notes. For positive (+) settings, keyboard
velocity will speed up the T1 time. For negative (-) settings, keyboard velocity will slow
down the T1 time.

ENV T4 SENS
(TVF envelope time 4 velocity
sensitivity)

-63–+63

Use this parameter when you want key-off velocity—the speed at which you release a
key—to affect T4 (Time 4) of the TVF envelope. With higher settings, the T4 value will
change more significantly depending on whether you release the key slowly or quickly.
With positive (+) settings, faster key-off velocity will reduce the T4 setting. With negative
(-) settings, faster key-off velocity will increase the T4 setting.

ENV T1–T4
(TVF envelope time 1–4)

0–127

Specify the TVF envelope times. Higher settings lengthen the time until the next cutoff
frequency level is reached. (For example, T2 is the time over which L1 changes to L2.)

ENV L0–L4
(TVF envelope level 0–4)

0–127

Specify the TVF envelope levels. These settings specify how the cutoff frequency changes
at each point, relative to the standard cutoff frequency.

LEVEL
(Rhythm tone level)

0–127

This sets the Rhythm Tone’s basic volume. This setting is useful primarily for adjusting
the volume balance between Rhythm Tones in a Rhythm Set.
* The overall volume of the Rhythm Set is set by the Level (Rhythm Set Level, p. 63) setting,

raising or lowering the Tone level settings of its individual Rhythm Tones by the selected
amount.

VEL CURVE
(TVA level velocity curve)

FIXED, 1–7

This setting allows you to select from seven velocity curves that determine how the
force with which the keyboard is played is to affect the Rhythm Tone’s volume. When
set to “FIXED,” the Rhythm Tone’s volume will not be affected by the force with which
the keyboard is played.
