Hi all Help for a newbie. Can anyone please give me some advice. I have a new wk7600 and I wish to play midifiles stored on an Sd card through the keyboard. I have worked out how to do this but was wondering is there any way you can mute a particular channel to stop the sound playing while still hearing the rest of the channels instruments? I have many midifiles and the lead voice seems to be on channel 4 so I wish to just mute the channel and play the lead myself. Any help greatly appreciated. Gary
