Check Your MIDI Interface
(1) Make sure that your MIDI keyboard is turned on.
(2) Take a look at the MIDI Input Device List below and verify that your MIDI keyboard or your keyboard's MIDI interface is shown in the list below. If there is no text in the box below, click the browser back arrow key and click "Check your MIDI interface" again.
If your MIDI keyboard or your keyboard's MIDI interface is not shown in the list, one of the following may be the problem:
(a) Your cables are not firmly connected or are not connected correctly. Please check the cables. If they were loose or incorrectly connected, please quit your web browser and then relaunch it and come back to this page.
(b) If you are using a MIDI interface that has cables that connect to the "MIDI IN" and "MIDI OUT" ports of your keyboard, you may have connected them incorrectly. Try reversing the cables. Reversing the cables will not hurt anything.
(c) Your MIDI keyboard or MIDI interface is in use by another application (which can be a problem on some Windows computer setups). If you have other MIDI programs running, please quit them as well as this web browser. Then relaunch your web browser and come back to this page. In rare instances, it will also be necessary to restart the computer.
(d) Many keyboards and MIDI interfaces require the installation of a MIDI driver in order for your computer to recognize the device. If your MIDI keyboard or your MIDI interface requires the installation of a driver, make sure that you have installed the latest driver that is downloadable from the manufacturer's website.
(3) If you have to install or update the MIDI driver, you may need to restart your computer.
