Xpand!2 Pressure Controls

Many MIDI keyboards provide pressure (also called aftertouch) to generate a MIDI control signal which depends on how hard you press down held keys after the initial “note on.”

With Xpand!2 you can use this control signal to modulate a number of useful controls.

Pressure Destination

Select a destination for the modulation using pressure (aftertouch) from the pop-up menu.

 

Pressure Destination button

 

The following destinations for pressure action are provided:

 

Pressure Destination	Description
Pitch	Affects the Part’s pitch.
Wave	Changes the sound in different ways, depending on the selected Part. For example, shaping waveforms, FM modulation depth, sample start point offset, detuning.
Filter	Affects the Part’s filter cutoff frequency.
Volume	Affects the Part’s volume level.

Depth

This knob sets how much the signal is affected by the pressure control signal. Depth is a bipolar control, which means that it can be set to positive and negative values.

 

Pressure Depth control

 

For example, with destination set to Filter, applying aftertouch increases (positive Depth value) or decreases (negative Depth value) the filter cutoff frequency.
