Artaher,

All general midi formats are the same. Instrument manufacturers each have their own instrument format for special reasons. Midi is limited to the number of instrument sounds and quality settings. The manufacturers use their own format because it allows more instruments, quality settings, versatility and, some believe sound better than midi. They are not concerned with their files being able to be used on other instruments. The Technics instruments can save music to either the Technics format or the Standard Midi File format (smf). I work with midi files a lot on my KN6500 because I find them easier to work with, and I like to work with them on my computer and then play them on my keyboard. I have 600 midi songs that I have set up for my keyboard, and I like the sound of each one. You can load a midi file into a keyboard and save it as the specific keyboard format, and you can save a specific keyboard format as a midi file. The versatility is there, you just have to decide what you want to do. I hope this helps a little. If you have any questions, just post.
