Keystation 61es - Doubled notes in Logic Pro X 10.2.2


i have a keystation 61es plunged with my macbook Pro model 2012

i use Logic Pro x vers. 10.2.2

if i try to play a instrument in Logic with the key station i hear a double tone , like i drop two times the button and after them there will don ́t stop the tone . And the octaves on the left side are not the highest . two octaves from the left side are deep tone and after there begins the normal highest tone

in the midi monitor i see came a response from the key station if i play them

is the keystation not compatible with the new software from apple ?

Please don ́t worry with my english i am from Germany
