Getting error with PBValue

[mat-tgn]

Validating the code from PB Example on board Arduino Leonardo i get this error

"Compilation error: 'PBValue' does not name a type"

It must be something simple, but I can't figure out what I'm doing wrong.

`
#include <Control_Surface.h>

USBMIDI_Interface midi;

// Instantiate an object that listens for MIDI Pitch Bend messages on channel 1.
PBValue pb {Channel_1};

void setup() {
Control_Surface.begin();
Serial.begin(115200);
}

void loop() {
Control_Surface.loop();
// If the Pitch Bend value changed
if (pb.getDirty()) {
// Print it
Serial.println(pb.getValue());
// Clear the dirty flag to acknowledge the change
pb.clearDirty();
}
}`

Which version of Control Surface are you using?
