So, I have a Casio MA 150 and I've been trying to connect it to FL Studio. Casio MA 150 has a MIDI out and I bought a midi-usb cable and tried to connect it. FL studio detects the midi controller but when I press the keys, it doesn't really work. I tried putting both MIDI out and MIDI in ports but tough luck for both. Although, when I connect MIDI IN of the cable to MIDI out of the keyboard, few unusual sounds start coming. Can anyone help please ?
