Velocity Control
Velocity is usually used to control various parameters according to how hard or soft
you play notes on your keyboard. A REX file does not contain velocity values on its
own. And when you create sequencer track data by applying the “To Track” function,
all velocities are set to a default value of “64”. As velocity information is meant to re-
flect variation, having them all set to the same value is not meaningful if you wish to ve-
locity control Dr.Rex parameters.
There are basically two ways you can apply “meaningful” velocity values to REX files:
• After creating track data, you can edit velocity values in the Velocity Lane in the se-
quencer.
• You can play slices in real time on your keyboard. The resulting data will have ve-
locity values reflecting how the notes were struck when you played.
When velocity values have been adjusted, you can control how much the various pa-
rameters will be affected by velocity. The velocity sensitivity amount can be set to ei-
ther positive or negative values, with the center position representing no velocity
control.
The following parameters can be velocity controlled:
Pitch Bend and Modulation Wheels
The Pitch Bend wheel is used for “bending” the pitch up or down. The Modulation
wheel can be used to apply various modulation while you are playing the loop. Virtually
all MIDI keyboards have Pitch Bend and Modulation controls. Dr.Rex 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 key-
board at all. The wheels mirror the movements of the corresponding 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:
| Parameter |Description
Amp This let’s you velocity control the overall volume of the file. If a posi-
tive value is set, the volume will increase with higher velocity values.
F. Env This sets velocity control for the Filter Envelope Amount parameter.
A positive value will increase the envelope amount with higher veloc-
ity values. Negative values invert this relationship.
F. Decay This sets velocity control for the Filter Envelope Decay parameter. A
positive value will increase the Decay time with higher velocity val-
ues. Negative values invert this relationship.
|Parameter |Description
F. Freq This sets modulation wheel control of the filter frequency parameter.
A positive value will raise the frequency if the wheel is pushed for-
ward. Negative values invert this relationship.
F. Res This sets modulation wheel control of the filter resonance parameter.
A positive value will increase the resonance if the wheel is pushed
forward. Negative values invert this relationship.
F. Decay This sets modulation wheel control for the Filter Envelope Decay pa-
rameter. A positive value will increase the decay if the wheel is
pushed forward. Negative values invert this relationship.
