Sound Parameter

Largo User´s Manual

multiplication of the source signal and this parameter, the
resulting amplitude depends on the type of modulation
source you select:

•

For the so-called unipolar modulation sources, the
resulting amplitude lies within the range of 0…+1,
if  Amount  is  positive  or  0…-1,  if  Amount  is
negative.  These  sources  are:  all  envelopes,  all
MIDI  controllers  including  Modwheel,  Foot
control etc., Velocity, Release Velocity, Aftertouch
(Pressure) and Polyphonic Pressure.

•

For  the  so-called  bipolar  modulation  sources,  the
resulting  amplitude  lies  within  the  range  of  -
1…0…+1.  These  sources  are:  all  LFOs,  Keytrack,
Pitchbend and the Modifiers.

Dest (Destination)

see table Modulation Destinations

This pop-up menu defines the modulation destination.

Modifier

Modifiers allow you to apply mathematical functions on
modulation signals. Depending on the function type
selected,
calculation
will

affect

two  source  signals  or  a  source  signal  and  a  constant
parameter.  You  can  use  up  to  four  independent  modifier
units. The result of each operation is not directly audible,
but  is  used  as  input  source  for  the  Modulation  Matrix.
Moreover,  you  can  use  it  as  source  for  yet  another
modifying process.

The parameter for the modifiers can be found after the
pages of the Modulation slots. Please select these pages
with the

Selection Dial

an.

Src A (Source A)

see table Modulation Sources

Selects the first source signal used for the calculation.

Src B (Source B)

Const / see table Modulation

Sources

Selects  the  second  source  signal  when  two  sources  are
required  for  the  calculation.  See  description  of  modifier
functions  for  further  details.  The  possible  settings  are  the
same  as  for

Source A

with one exception: “

Off

” is

replaced by “

constant

” meaning that the calculation is

performed with a constant value that you can set up with
the

Constant

parameter.
