Do you have a reference that would work fine with a CT-640 ?

Ok thank you so much.

I tried on an USB 2 and an USB 3 port, same issue.

Hello. It's this one : https://www.aliexpress.com/item/4000250264687.html

Hi. I have a Casio CT-640 and I'm trying to use it with my computer (windows 10 laptop) via a midi/USB cable. I can't figure out how to solve this problem : Input is working just fine, I can send midi from the computer and the keyboard plays it. If a press a key, on the keyboard it will play a note on the computer. Sound is working fine on the ct-640 but the midi ouput seemingly is able to send only one single note, the first I press. I tested both in ACID 4 and in Midi-OX. In the midi console of Midi-OX, same thing, only one note appear (cf. pic). The strangest thing is that if on the keyboard I change the chord/midi selector,exit the midi position, and get back to it I can play another single note. Does anyone experienced the same issue ? Am I missing something ? A setting ? Should I worry about the cheap chinese Midi/Usb cable ? Or the venerable but not so young casio ? I unfortunately do not have another keyboard to test the cable... Any help would be really apreciated, I'm stuck. Thank you and take care. Sam
