Interesting. I have many MIDI files on my old web page that I made back in the day and they all play fine in older Quicktime 7 here. Some sound a bit different than on a Windows system because the Midi sounds are a bit different but they still sound ok. I am quite sure my friends Midi's that he makes play here also. Will check that later and report back. Not sure what is going on.
Dave, did you read Mine and Craigs post?
I will find you a url to Quicktime 7. Install that. New quicktime will still work, but in QT7 you can not only play Midi's but use Perian and Flip4Mac like before Mavericks.
I have a Mac OS 10.7.5.
I cannot play MIDI files -- I've downloaded Quicktime 7 into Applications/Utility folder, but still -- NOTHING! I'm a novice at this… can anyone walk me through this please?? Thank you!!
