Diki , when a musician pay 4,000 - 5,000 $ for an arranger key the company that sale the key should make one that includes most of the popular styles and sounds , and dance/house/hiphop/trance/ from the 21 century are very popular so i do not understand Ketron that makes almost only dance from the eighties or disco from the seventies . we are in 2024 . shame on them that i need to pay more money for contemporary dance styles and sounds.
