In this code, how can I change it so that when a midi signal is received, a servo motor moves instead of an led lighting up

I want to use this code so that whenever I hit a note on my drums, a servo motor moves. right now an led lights up when the signal is received. How can I change it so that a motor moves instead of an led lighting up? I have my code below.

[code]
#include <MIDI.h>  // Add Midi Library

#define LED 13    // Arduino Board LED is on Pin 13

//Create an instance of the library with default name, serial port and settings
MIDI_CREATE_DEFAULT_INSTANCE();

void setup() {
  pinMode (LED, OUTPUT); // Set Arduino board pin 13 to output
  MIDI.begin(MIDI_CHANNEL_OMNI); // Initialize the Midi Library.
  // OMNI sets it to listen to all channels.. MIDI.begin(2) would set it 
  // to respond to notes on channel 2 only.
  MIDI.setHandleNoteOn(MyHandleNoteOn); // This is important!! This command
  // tells the Midi Library which function you want to call when a NOTE ON command
  // is received. In this case it's "MyHandleNoteOn".
  MIDI.setHandleNoteOff(MyHandleNoteOff); // This command tells the Midi Library 
  // to call "MyHandleNoteOff" when a NOTE OFF command is received.
}

void loop() { // Main loop
  MIDI.read(); // Continuously check if Midi data has been received.
}

// MyHandleNoteON is the function that will be called by the Midi Library
// when a MIDI NOTE ON message is received.
// It will be passed bytes for Channel, Pitch, and Velocity
void MyHandleNoteOn(byte channel, byte pitch, byte velocity) { 
  digitalWrite(LED,HIGH);  //Turn LED on
}

// MyHandleNoteOFF is the function that will be called by the Midi Library
// when a MIDI NOTE OFF message is received.
// * A NOTE ON message with Velocity = 0 will be treated as a NOTE OFF message *
// It will be passed bytes for Channel, Pitch, and Velocity
void MyHandleNoteOff(byte channel, byte pitch, byte velocity) { 
  digitalWrite(LED,LOW);  //Turn LED off
}
[/code]

do you know how to drive a servo ?

There are many examples in the IDE for driving a servo. Start with one of those. Figure out how it works and then incorporate that into your MyHandleNoteOn and MyHandleNoteOff routines to do what you want.

Replace the digitalWrite(LED, something); with servo.write(angle);
