Hi
Sysex stands for System Exclusive messages. They are little lines of code numbers that can be inserted into a MIDI file & sent to the keyboard to set it up a certain way before the MIDI song starts playing. Every different keyboard/module manufacturer has different code numbers to accomplish the same thing - such as set the reverb. That is why they are called System Exclusive. If you look in your i30 Owner Manual, usually at the very back, there will be a list of all these Sysex messages, and what they do. I will leave it to another to explain how to get the Sysex codes into measures 1-3 of your MIDI file.
