I have a Korg i30 and would like to know how to change the key of any given song in a standard midi file. It seems that everything else is readily accessible, but not the key signature. Thank You, Big Red.

When I used to own the I30, i had the same trouble.. I am afraid the only way I found to do it is changing the transpose track by track via the menu option. As far as I know there is no 'song only' transpose button. The only other option the I30 has which was of no use to me, was to disable the midifile transpose whilst adjusting the master keyboard transpose. This was no use because if a song was too high, you were going to play it high anyway. Korg should of thought about doing it the other way round!

the best way is to do it track by track unfortunately..
