Chapter 6. Creating Rhythm Sets

TVA VELOCITY

Velocity Sens

(TVA Envelope Velocity Sensitivity)

Specifies how keyboard playing dynamics will affect the depth of the TVA envelope. Positive (+) settings will cause the TVA envelope to have a greater effect for strongly played notes, and negative (-) settings will cause the effect to be less.

Velocity Curve (TVA Envelope Velocity Curve)

Selects one of the following seven curves to specify how keyboard dynamics will affect the TVA envelope. Set this to FIXED when the amount of TVA Envelope applied is not to be changed according to the force with which the keys are pressed.

TVA TIME ENV (TVA Time Envelope)

Here you can make settings for the TVA envelope (time-

variant changes in volume).

V-T1 (TVA Envelope Time 1 Velocity Sensitivity)

Use this parameter when you want keyboard playing (velocity) to affect T1 (Time 1) of the TVA envelope. If you want T1 time to be speeded up for strongly played notes, set this parameter to a positive (+) value. If you want it to be slowed down, set this to a negative (-) value.

V-T4 (TVA Envelope Time 4 Velocity Sensitivity)

Use this parameter when you want key-release speed to influence the T4 (Time 4) value of the TVA envelope. If you want T4 time to be speeded up for quickly released notes, set this parameter to a positive (+) value. If you want it to be slowed down, set this to a negative (-) value.

TVA ENVELOPE

T1–T4 (TVA Envelope Time 1–4)

Specify the TVA envelope times (T1–T4). Larger values result in longer times until the next volume is reached (for instance, T2 controls the time from L1 until L2 is reached).

L1–L3 (TVA Envelope Level 1–3)

Specify the TVA envelope levels (L1–L3). These settings specify how the volume will change at each point, relative to the standard volume (the Rhythm Tone Level value specified in the TVA page).
