Can i plug my keyboard Midi output to an external speaker?So that i sound better?

Hi and good question. Unfortunately, MIDI (short for Musical Instrument Digital Interface) cannot output audio. So here is what you might want to do instead. Simple plug the audio outputs of your keyboard into a home theater amplifier. Or even better, use a pair of powered studio monitors and you can even hook up your laptop to the powered monitors. You will need a stereo mini plug and two audio cables. Personally, I prefer using powered montiors for mixing instead of a home theater set up.
