Hello again PIONEER!sorry 2 disturb u again...but until now i still cant get my ddm4k to work on my loptop (1st loptop/intel core duo),i even uninstall the latest update of TSpro(1st loptop) coz maybe im thinkin that it will work also w/o the latest update just what i did on my netbook,but still i didnt work,then i thought of putting the license and the latest update on my netbook and surprisingly it work..i even manage to follow ur thread regarding routing the music from my mixer (but i stil cant figure it out how to blink the leds from my mixer)...nwei,nevermind the blinking leds first...i think the problem was on my loptop's usb port coz its not responding to the ddm4k midi cable,i notice it when i did the same setup from my netbook(working),but when i hook the exact setup/settings to my 1st loptop it is not responding the music does go out from my mixer with the audio 8 connected but controlling it thru ddm4k,it fails....do i need to install something/driver on my 1st loptop to make it work?is there any help u can tell me to use my netbook on tspro regarding that the cpu usage on top is goin high that i can hear crackles while mixin on it...i dont want to gamble using netbook on tspro specially if im goin on a gig!waiting again from u man!thanx!
