SUBTRACTOR SYNTHESIZER
119
The following parameters can be velocity controlled:
Pitch Bend and Modulation Wheels
The Pitch Bend wheel is used for “bending” notes, like bending the strings on a guitar.
The Modulation wheel can be used to apply various modulation while you are playing.
Virtually all MIDI keyboards have Pitch Bend and Modulation controls. Subtractor fea-
tures not only the settings for how incoming MIDI Pitch Bend and Modulation wheel
messages should affect the sound. Subtractor also has two functional wheels that
could be used to apply real time modulation and pitch bend should you not have these
controllers on your keyboard, or if you aren’t using a keyboard at all. The Subtractor
wheels mirror the movements of the MIDI keyboard controllers.
Pitch Bend Range
The Range parameter sets the amount of pitch bend when the wheel is turned fully up
or down. The maximum range is “24” (=up/down 2 Octaves).
Modulation Wheel
The Modulation wheel can be set to simultaneously control a number of parameters.
You can set positive or negative values, just like in the Velocity Control section. The
following parameters can be affected by the modulation wheel:
|Destination |Description
Amp This let’s you velocity control the overall volume of the sound. If a pos-
itive value is set, the volume will increase the harder you strike a key.
A negative value inverts this relationship, so that the volume de-
creases if you play harder, and increases if you play softer. If set to
zero, the sound will play at a constant volume, regardless of how hard
or soft you play.
FM This sets velocity control for the FM Amount parameter. A positive
value will increase the FM amount the harder you play. Negative val-
ues invert this relationship.
M. Env This sets velocity control for the Mod Envelope Amount parameter. A
positive value will increase the envelope amount the harder you play.
Negative values invert this relationship.
Phase This sets velocity control for the Phase Offset parameter. This applies
to both Osc 1 & 2, but the relative offset values are retained. A posi-
tive value will increase the phase offset the harder you play. Negative
values invert this relationship.
Freq 2 This sets velocity control for the Filter 2 Frequency parameter. A pos-
itive value will increase the filter frequency the harder you play. Nega-
tive values invert this relationship.
F. Env This sets velocity control for the Filter Envelope Amount parameter. A
positive value will increase the envelope amount the harder you play.
Negative values invert this relationship.
F. Dec This sets velocity control for the Filter Envelope Decay parameter. A
positive value will increase the Decay time the harder you play. Nega-
tive values invert this relationship.
Osc Mix This sets velocity control for the Osc Mix parameter. A positive value
will increase the Osc 2 Mix amount the harder you play. Negative val-
ues invert this relationship.
A. Attack This sets velocity control for the Amp Envelope Attack parameter. A
positive value will increase the Attack time the harder you play. Nega-
tive values invert this relationship.
|Parameter |Description
F. Freq This sets modulation wheel control of the Filter 1 Frequency parame-
ter. A positive value will increase the frequency if the wheel is pushed
forward. Negative values invert this relationship.
F. Res This sets modulation wheel control of the Filter 1 Resonance param-
eter. A positive value will increase the resonance if the wheel is
pushed forward. Negative values invert this relationship.
LFO 1 This sets modulation wheel control of the LFO 1 Amount parameter.
A positive value will increase the Amount if the wheel is pushed for-
ward. Negative values invert this relationship.
Phase This sets modulation wheel control of the Phase Offset parameter for
both Osc 1 and 2. Note that Phase Offset Modulation (Subtraction
or Multiplication) must be activated for this to have any effect (see
page 110).
FM This sets modulation wheel control of the FM Amount parameter. A
positive value will increase the FM amount if the wheel is pushed for-
ward. Negative values invert this relationship. Both oscillators must
be activated for this to have any effect.
