Question about MIDI library

Question

I'm trying to replace this code with something that uses the Arduino MIDI library:

#include <SoftwareSerial.h>

#define rxPin 2
#define txPin 1

SoftwareSerial midiSerial (rxPin,txPin);

void setup() {
  midiSerial.begin(31250); }

while ( midiSerial.available()) {
    incomingCommand = midiSerial.read();
    incomingNote = midiSerial.read();
    incomingVelocity = midiSerial.read()*8.05511811024; 
  if (incomingVelocity <=1023) {
    midiSerial.write(incomingCommand);
    midiSerial.write(incomingNote);
    midiSerial.write(incomingVelocity); } }

Here's what I came up with:

#include <MIDI.h> // MIDI Output
MIDI_CREATE_DEFAULT_INSTANCE();

byte MIDIChannel;
byte programByte1;
byte controlByte1;
byte controlByte2;

void setup() {
  MIDI.begin();
}

void loop() {
 if (MIDI.read()) switch (MIDI.getType()) {
      MIDIChannel = MIDI.getChannel();
    case midi::ProgramChange:
      programByte1 = MIDI.getData1();
      break;
    case midi::ControlChange:
      controlByte1 = MIDI.getData1();
      controlByte2 = MIDI.getData2();
      break; 
    default: break; 
    }
}

Does that look correct? It doesn't function as smoothly as the version that uses SoftwareSerial
