Today, I attempted to use my Casio Celviano AP-15 as a MIDI controller by plugging it into my PC with a MIDI to USB cable. I could not find MIDI drivers for this model but I plugged it in anyway. FL studio recognized the keyboard as "USB A" so I set that as the input and output but there was no response from the keyboard. The MIDI in and out indicators on the wire flashed briefly when I plugged it in but did not light up afterwards. I assume that finding appropriate drivers will fix this issue. If otherwise, is there anything else I can do to get this to work? Many thanks.
