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 ve-

locity information is meant to reflect variation, having them all set to the same

value is not meaningful if you wish to velocity 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 sequencer.

• You can play slices in real time on your keyboard. The resulting

data will have velocity values reflecting how the notes were struck

when you played.

When velocity values have been adjusted, you can control how much the

various parameters will be affected by velocity. The velocity sensitivity

amount can be set to either positive or negative values, with the center posi-

tion 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 Modu-

lation wheel can be used to apply various modulation while you are playing

the loop. Virtually all MIDI keyboards have Pitch Bend and Modulation con-

trols. 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 keyboard 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 pa-

rameters. 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 positive value is set, the volume will increase with higher

velocity values.

F. Env This sets velocity control for the Filter Envelope Amount pa-

rameter. A positive value will increase the envelope amount

with higher velocity values. Negative values invert this rela-

tionship.

F. Decay This sets velocity control for the Filter Envelope Decay pa-

rameter. A positive value will increase the Decay time with

higher velocity values. Negative values invert this relation-

ship.

Parameter

Description

F. Freq This sets modulation wheel control of the filter frequency pa-

rameter. A positive value will raise the frequency if the

wheel is pushed forward. Negative values invert this rela-

tionship.

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 re-

lationship.

F. Decay This sets modulation wheel control for the Filter Envelope

Decay parameter. A positive value will increase the decay if

the wheel is pushed forward. Negative values invert this re-

lationship.
