Hi,
I just received our LK-S250. We connected the usb to our iPad. We are having problems separately adjusting the volume on the keyboard and the midi file. The midi file is too loud and the keyboard volume is too low. The keyboard volume adjustment buttons make the midi even louder when we try to make the keyboard louder. We can barely hear the keyboard over the midi. Also the App buit-in sound is off. Please help us figure out how to make the speaker volume on the keyboard lower for the midi and higher for the keyboard. Thank you kindly
