The Distortion Parameters - Yamaha VL70-m Owner's Manual

The Distortion Parameters

Distortion is an excellent way to drastically change a sound — although subtle distortion settings can
produce surprisingly delicate variations.
Type
• Distortion Type
• Settings: THRU, DISTORTION, OVERDRIVE, 3-BAND EQ
Selects the distortion type, or "THRU" if no
distortion effect is required. Refer to the separate
"List Book" for brief descriptions of each of the
distortion types.
Type-Specific Distortion Parameters
• See separate "List Book"
Each of the distortion types, selected via the
"Type" parameter, above, has a different set of
parameters that specify the actual distortion sound.
Refer to the separate "List Book" for information
on the individual parameters for each distortion
type.
AT DstCtrl
• Aftertouch Distortion Control
• Settings: -64 ... +63
Aftertouch distortion control allows one of the
selected distortion effect parameters to be con-
trolled in real time via keyboard aftertouch pres-
sure. The parameter which can be controlled is
individually preset for each distortion effect type
(see the separate "List Book"). The "AT DstCtrl"
parameter determines to what degree the effect
parameter is affected by aftertouch pressure. For

Effects & Effect Editing
example, if the OVERDRIVE effect is selected
aftertouch controls the "Drive" parameter. In this
case higher positive "AT DstCtrl" values cause
increased aftertouch pressure to increase the
amount of drive, while higher negative values
cause increased aftertouch pressure to decrease the
amount of drive. If this parameter is set to "+00"
aftertouch control has no effect.
AC1DstCtrl
• Assignable Controller 1 Distortion Control
• Settings: -64 ... +63
Assignable Controller variation control allows one
of the selected distortion effect parameters to be
controlled in real time via assignable controller 1
(page 54). The parameter which can be controlled
is individually preset for each distortion effect type
(see the separate "List Book"). The "AC1DstCtrl"
parameter determines to what degree the effect
parameter is affected by the controller. For ex-
ample, if the OVERDRIVE effect is selected the
controller affects the "Drive" parameter. In this
case higher positive "AC1DstCtrl" values cause
increased controller settings to increase the amount
of drive, while higher negative values cause
increased controller settings to decrease the amount
of drive. If this parameter is set to "+00" assign-
able controller 1 has no effect.
