Just FANTASTIC Ted Nicely answered and thanks a ton for giving time for me. I have downloaded Data Manager 6, which ran perfectly on a desktop with XP, but not working on my laptop having windows 7, 32bit. Error on Visual C++ runtime. I will try on weekend to uninstall Visual studio and then will see or I will try with backward compatibility mode. Regarding using CTK as slave you have explained that why it cannot be done. I dont have another keyboard. Have you tried to send left hand fingered chords from a second keyboard to CTK/WK while on ACCOMP mode? Nice to discuss with you. Have nice time. Regards S Ghose
