_saveMIDI (line 180)

Saves MIDI file in designated tmp directory and returns the src attribute

Uses Valentin Schmidts Midi Class 1.6 to create the MIDI file. This package can be downloaded from http://staff.dasdeck.de/valentin/midi/. Since Midi Class 1.6 uses Call-time pass-by-reference, I set the error level to supress warnings while opening the midi.class.php file if allow_call_time_pass_reference is set to off in php.ini.

return: value of the src attribute (file path) to the saved MIDI file
access: private

string _saveMIDI ()
