Dear Eddy
Thank you for your respose. What I understood from your posting few days ago on the oriental X1 is that you do not need anymore the quarter tone convertion box (which comes as a standard part of the oriental kit upgrade for the standard X1). In the New X1 the quarter tone is instantaneously available through the 13 buttons of the parts volume , and that you can change the tone of any note as you play. if my understanding is correct then the difference berween the standard and the new oriental X1 is not only limited to the X_Y switch. Please correct me if I am wrong.
