MIDI library conflict?

Using Arduino Audio
32

to clarify, this is one that was looping in setup; I have a feeling the 2nd SD.begin is not needed.

void setup() {
 

 MIDI.begin(MIDI_CHANNEL_OMNI);
//  Serial.begin(57600);
   pinMode(MIDI_ENABLE, OUTPUT);      // sets the digital pin as output 
  digitalWrite(MIDI_ENABLE, HIGH);
  //  MIDI.turnThruOff();

  //   MIDI.setHandleClock ( HandleClock );


  //MIDIfile & SD card setups
  // Initialise SD
  if (!SD.begin(chipSelect, SPI_HALF_SPEED))SD.initErrorHalt();
  // Serial.println("begin success");
 
  SD.begin(chipSelect, SPI_HALF_SPEED);

  // Initialise MIDIFile
  SMF.begin(&SD);
  SMF.setMidiHandler(midiCallback);
//  SMF.setSysexHandler(sysexCallback);
//MIDI.setHandleNoteOn(HandleNoteOn);
 MIDI.sendProgramChange(P,10);   
}
