Reason for being junk: When connected to a PC and playing MIDI files with a sequencer, the indicators are working, but there is a buzzing noise from the Audio OUTPUT and Phone jacks, and no sound is produced. All four rubber feet on the bottom are missing. I feel it's a waste to throw it away, so I'll give it to someone who can fix it. Also, I am selling it elsewhere, so if it sells there, I apologize, but I will have to cancel the sale.
