Hi, i have a Casio ctk 591 that i have since around 2007 when i was a kid. in the last years i haven't used it at all, but i wanted to start using it again but as a midi controller, so i bought a cheap usb to midi cable, the program i use recognizes the usbmidi cable and i can play some notes ok, but some other keys play a sustained high pitched note, for example: i play a key in the second octave and the program says its playing the key on the 11th octave.
Now my question is what its the problem, i dont know if the midi cable its just bad or if there is somethign with the keyboard, maybe some configuration or some driver.
Thanks.
