La unica queja que tengo sobre este teclado es el tamaño de sus teclas (keyboard) pero por lo demas es un gran teclado con sequenciador de 8 pistas vector synth sistema de volcado a sysex, pads de percusion y efectos yo suelo usarlo con un controlador midi de teclado grande y sencibilidad al toque aconsejaria hacer eso pero vale la pena comprar uno
