Opening a midi file (.mid) in GarageBand is the easiest thing ever, but how do I go the other direction? I want to take a piece I recorded as a midi performance in GarageBand and turn it into a midi file. How can this be done?
Background:
- I have GarageBand 10.1.6
- I record midi performances all the time in GarageBand and can easily export them as an MP3
- I want to save/export them as midi files so that I can open them in Synthesia (Synthesia only opens midi files)
Best Answer
You can get MIDI from GarageBand using these free application or browser conversion methods
Kobbe also created an experimental JavaScript-based version of the GB2MIDI app which works directly in your browser. This is great because, if the application ever stops working (e.g. after updating your operating system), the browser version still works wonderfully!
Conversion Process
Once you have your MIDI performance in GarageBand, you may create a MIDI file (.mid) using the following steps:
Now you can use the MIDI file for whatever you wanted. In my case, I'd open the MIDI file in Synthesia. Thanks to this process, I can make videos like this one.
