I understand that you are trying to find the number of notes in the MIDI and .wav files.
Notes in a music piece are essentially set of frequencies varying with different octaves. I suggest you can convert the piece to frequency domain and note the different frequency variations.
You can analyze the MIDI file using the MIDI Toolbox and there is a file on the MATLAB central File Exchange available for the same purpose. You can find it on the following link:
For .wav file the process is similar. You can read the file using the audioread function.
For further information on the audioread function please refer the following link:
