Saving Your MIDI Data
For the most part, saving MIDI data in your sequencer program is like saving data in any computer program. Yep, you need to click the Save button (or press cmd+S if you have a Mac). Don’t forget to save your work regularly, lest your computer crashes and you lose several hours’ work.
The main thing to know about saving data in a sequencer program is that most programs have their own proprietary file format. You generally can’t take a saved file from your program and play it on another one.
If you want to play your MIDI tracks on another sequencer program or make it available on the Internet for other people to play, make sure that you save your music as an SMF (Standard MIDI Format) file. Nearly all sequencer programs allow you to save in this format. Some even do this by default.
Check your owner’s manual to see how to do this. Then you can give your MIDI tracks to anyone who can play an SMF file, and if you recorded your stuff by using a GM standard, it sounds just how you intended it to sound, regardless of the listener’s gear.
