Chapter 5. Creating Patches
TVA TIME ENV (TVA Time Envelope)
fig.05-80
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.
Time Keyfollow
(TVA Envelope Time Keyfollow)
Use this parameter when you want keyboard position to
affect TVA envelope times (T2–T4). Based on the TVA
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. Higher values will cause more
change.

TVA ENVELOPE

fig.05-81
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).
To edit the overall Patch while preserving the relative
differences in the T1 parameter (Attack Time) values set
for each Tone, set the Atk parameter (PATCH/
COMMON/PATCH MODIFY) (p. 71). Similarly, to edit
the overall Patch while preserving the relative
differences in the T4 parameter (Release Time) values set
for each Tone, set the Rel parameter (PATCH/
COMMON/PATCH MODIFY) (p. 72).
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 Tone Level value specified in the
TVA page).
