Hi everyone, I'm new in this forum, recently I bought a Casio LK 280 to start playing piano, but I don't know if there is a midi secuence library to this keyboard, I tried download a diferent MIDI songs from the internet but the lightning key board doesn't light only plays the song. I configured the songs to the channel 3 and 4 but it doesn't work, so thats why ask you, if you know some songs for this keyboard that I can download? Thanks
