LPK 25 Won't Connect

I have an LPK25 with a connector and it does not seem to work. The top left button flickers occasionally, but the buttons do not respond at all. Did I receive a faulty connector, or is there something I am doing wrong? The computer I am using is a MacBook Air and the software I was trying to use was Melodics, included free with my keyboard.

  • Hey Alice,

    Thanks for posting!

    If the button that is flickering is the Tap Tempo button, that is normal. This button indicates the rate at which the LPK's internal clock is running. Melodics walks you through the process of configuring your MIDI controller in a pretty clever way so let's make sure your LPK is actually sending MIDI to your computer.

    We can verify whether your LPK is sending MIDI data to your computer with MIDI monitoring software. A MIDI monitor will show you all the incoming data from any MIDI controllers or MIDI interfaces that you have connected to your computer.

    For testing MIDI devices on Mac:
    Download snoize: MIDI Monitor

    Select the LPK as a MIDI input source in the monitor and send some data with its keys and controllers. If you see data appear in the input monitor window, the controller is sending MIDI data to your computer and will only need to be configured for MIDI input in the software you're using. Make sure all other MIDI software is closed and you follow the step by step instructions in Melodics to set up your controller.

    If the LPK is not sending MIDI data to the monitor, let's test the connection between the controller and the computer. Try connecting the controller with a different USB cable, with different USB ports on your computer, and to a different computer to see if you can reproduce the same behavior. Be sure to connect directly to the computer via USB and avoid using any USB hubs or adapters.

    If you try the steps listed above and you are still unable to send MIDI data with the controller, it sounds like your product may need to be serviced. Warranty and non-warranty claims are not handled here on the forum, but I can point you in the right direction! Here are a couple of options that you could choose from:
