So i have a MIDI Keyboard, plugged in my MIDI to USB cable in the correct ports etc. then when I go to play a key through FL, it's very intermittent. Like hit and miss with what key I play. I have used MIDI-OX to pick up what's being pressed and it's the same story. But, when I change style on the keyboard, it picks up every single change straight away.
Sorry if this doesn't make sense, it's very difficult to explain but hopefully you understand.
