Thank you for viewing. I purchased this, but I'm selling it because I don't seem to have a chance to use it. I took it out of the box once for the purpose of taking photos. Immediate purchase is OK. Various chord progressions are converted into data. It recommends multiple next chords that connect smoothly from a single chord. With an intuitive performance interface and arrangement function, you can play chords, melodies, and rhythms as you like. You can create song ideas anytime, anywhere. Equipped with an 8-track sequencer and approximately 150 types of sounds.
