I am having an issue on my genos when i am using midi files with my saved registrations the problem is volume levels.some registrations load up with the midi file volume level very low even with volume set to max and some times other way around ,say i select an organ sound which i can make adjustments in mixer even with that cranked all the way is very low.it makes it very hard going from song to song maintaining volume levels.i know you can save all the settings with registrations,but the sound levels if set to max and still not enough and the issue is midi files as how to get more volume and no other way but on the main control panel on upper top left of keyboard
