I connect the controller and turn it on, turn on ableton, and as I press keys I can see the midi light go on and off, but I have no sound.
I then have to fiddle with settings in the preferences, and sometimes it works, sometimes it doesn't, mostly because I lose patience.
I don't have a dedicated sound card, and I'm using Asio4all driver.
I doubt my computer is the issue, i5 at 3.4Ghz, DDR3 16GB Ram, 1TB hard drive at 7200rpm, GTX650 1GB DDR5 graphics, but a proper soundcard is in the shopping list hoping it will solve the long setup time.
