Use iTunes to convert MIDI to audio files Apps
I teach music tech and digital audio at the University level and have never had much use for iTunes, as it seems to me to be designed mainly for teenagers' CD collections. But a colleague showed me this trick, and I was so floored I had to repeat it before I'd believe it.

As everyone knows, MIDI is not sound, but instructions for playback of sound. The actual sound is generated by the local synth (which makes MIDI a good choice for internet music). If you burn a MIDI file to CD, it's just data and can't be played on a CD player. You have to send the playback to a synth, record the synth in a digital editor and burn those files to create actual music files.

But create a playlist in iTunes with MIDI files, then burn that to CD and it burns audio files that can be played back on a CD player. I'm guessing it converts the QuickTime synth sounds in real time while burning. Not even ProTools has a similar feature. Pretty slick.

Use iTunes to convert MIDI to audio files

You don't need to burn the MIDI file to a CD and import it back, you can just select it and choose `Convert Selection to AAC' (or MP3 or whatever) from the `Advanced' Menu.

Yep this is a cool trick

I assumed iTunes would do this, since QuickTime supported MIDI.

Last Christmas, I scoured the internet for MIDI Christmas songs. I put them in iTunes and created several CDs for friends' parties. Worked like a charm.

…designed mainly for teenagers' CD collections?? Hardly. How else would you design a music library application for playing back songs, entire albums, or just any random song?

Use iTunes to convert MIDI to audio files

Slightly offtopic, but also for people who haven't looked for MIDIs in a long, long time that want to do this... :-)

I'm interested in using bluetooth on my PowerBook to move MIDI files from the PB to my cell phone... to use as ring tunes. It's actually pretty neat. What sites do you guys go to for quality MIDIs? (I've noticed that MIDIs as a whole seem to have gone into hiding ever since MP3s became popular).

Use iTunes to convert MIDI to audio files

If you're interested in converting MIDI to sampled audio, you might want to improve the quality of the resulting audio by changing the default QuickTime sound font. This has been covered previously on MacOSXHints.

Be aware that QuickTime is a soft synth and on slow Macs it may not be able to render MIDI sound in real time using a high-quality font. But I suspect a music tech teacher would have the latest G5:s at his disposal.

Funnily enough, the QuickTime default font is very good for its size and CPU requirements.

But... does anyone know how to convert .MOD files? There was a plug-in for SoundJam...

Use iTunes to convert MIDI to audio files
Authored by: j-beda on Aug 25, '06 06:53:16AM
It doesn't work any more in iTunes 6.0.3, 6.0.4, and 6.0.5 according to http://docs.info.apple.com/article.html?artnum=303429, which says:

iTunes: MIDI files cannot be converted in iTunes 6.0.3 - 6.0.5

Attempting to convert a MIDI file to another format in iTunes results in an alert message:

Error occurred while converting the file "filename". An unknown error occurred. (-50).

Products affected

* iTunes 6.0.3
* iTunes 6.0.4
* iTunes 6.0.5

Solution

If you have QuickTime Pro, you can export the MIDI files in QuickTime Pro to another audio format (such as WAV or AIFF) using QuickTime Player, and then convert those files in iTunes.
