Hi. everyone.
I have been using the aux. input for midifiles from an external roland midifile player/soundcard through the main output to an amplifier. My reason for this is that I can control the midifile volume independently
to the main keyboard volume for better balance. I have suddenly found that the midifile is not getting through to the amplifier, even though it is playing through the keyboard speakers. If someone can give me a hint as to the cause of this problem It would be most appreciated. Best regards Alan

I use line in, you have a volume control on the keyboard giving you an easy way to balance.

1-Main volume control
2-Control for midi files (line in)
3-Control for mic. if you user one.

Technicsplayer had posted some good information about the Aux impute about a month or so ago.
