Well , i took a look on E-Bay ... , seen the cable you are talking about ... you were right about the fact it doesnt need drivers

, and to be honest , i don't really have a clue so far ... due to the fact i never worked with such cables ... , but i guess it has to be something simple ... , Does these led's light up like hows its been described on E Bay ? ( LED's indicate power on, MIDI in signal and MIDI out signal. ) , if they aren't , then something aint right .... , wigle the cables a bit on the back of the keyboard , cos i know that these MIDI plugs loose contact easy ... ( Had my old keyboard midiplug tightly taped

)
If nothing on the above worked , try switching the MIDI-in and MIDI-out .... perhaps you mistaked ? , or me ...
Well , ...
Im empty with possibily's now ... , hope anyone else got some bright idea's for you ?
