Advance 49 knobs sending data randomly

I have my Advance 49 knobs setup to send CCs for effects to a VST (SampleTank 4). What happens is, every so often, the knobs fire off messages which throws my effects/settings all out of wack. They don't seem to settle into a value solidly and fluctuate sometimes. Is there a setting I can change to calm them down?

I saw on another post that an owner had a problem with a bad cable. I am using the out of box USB cable and have the Advance connected to its own USB port without an extra hub.

  • I got the same problem with an advance 61. I bought it 10 months ago. the malfunction builds over time (temperature?). an external power supply reduced this issue, but didn't fixed it.
    different usb cables don't have any effect.

  • Unfortunately this is a common malfunction. External power supply, better usb cables don't fix it.

  • Hey Rich,

    Thanks for posting!

    Sorry to hear you are having trouble. I suggest connecting the controller with a different USB cable, to 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 the issue persists, there may be an internal issue with the MIDI module. We can verify whether your Advance is sending random 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 PC:
    Download MIDI-OX

    This video will get you set up quickly for MIDI input monitoring in MIDI-OX:

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

    Select the Advance as a MIDI input source in the monitor and send some data with its keys and controllers. If you see randomized data appear that you did not trigger, like an encoder modulating on its own, 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:

    • Submit a Warranty or Service inquiry with our Technical Support team by logging onto the Akai Pro Support Page. Select Warranty or Service Inquiry from the drop down menu.

    or

    • For quicker support, call your nearest Support Office or International Distributor.

    Make sure to reference or link this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.
    • Eliza, I was about to try ordering the Akai power adapter but tried something else - it has fixed my random knob data problem for at least today. I tried an Anker 12W powered Hub in front of the USB connector for my laptop. Not only is this working (so far), but I was able to power my Novation MiniNova with this solution and it has eliminated hum/noise I was experiencing powering that over USB. Double-win!
    • Hey Rich,
