Issue with Sustain Pedal SP2 on Axiom 61, erratic signal sent to PC when pedal pressed or not.

Issue with Axiom 61 sustain pedal. As soon as sustain pedal is inserted in the midi keyboard. The screen code starts toggling between cc 64 cc 65,66,67,127. Even when pedal not pressed, some erratic signal is sent to the PC. The pedal was working fine earlier. Suddenly this issue is observed. Please help.

  • Hey Arjun,

    Thanks for posting!

    Sorry you're having some trouble with that! Let's try some troubleshooting and see if we can find the cause of those unexpected messages.

    The MIDI data that the Axiom is sending to your computer can be viewed 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:
    MIDI-OX

    This video will get you set up quickly for Input Monitoring in MIDI-OX:
    Monitoring MIDI Input with MIDI-OX

    For testing MIDI devices on Mac:
    snoize: MIDI Monitor

    Select the Axiom as a MIDI input source in the monitor to watch for the sustain messages that it is sending to the computer.

    To test the hardware, I would recommend two steps - trying the pedal with another MIDI controller and trying the Axiom with another sustain pedal. Cross testing your devices with other hardware will help determine the origin of the unexpected MIDI data.

    In order to reset the Axiom to its factory default settings, hold down the Patch Up and Down buttons while powering on the Axiom. Keep in mind that doing this will erase all previously saved data on the Axiom.

    If you're still having some trouble, you can test the connection between the Axiom and your computer to rule out a potential connection issue. Try connecting the Axiom with a different USB cable, with different USB ports on your computer, and with 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 above steps and you are still unable to send MIDI data with the controller, this sounds like it may be hardware related. Warranty and non-warranty claims cannot be 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 M-Audio Support Page. Select Warranty or Service Inquiry from the drop down menu. This will not require a support code.

    or

    • For faster support, call or email your nearest Support Office or International Distributor. Select your country to find the nearest office.

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

    I hope this helps! Let me know if you have any additional questions.

    Dear Nick,

    Thanks for the inputs. Please find the updates below:
    1) On checking with Midi OX- A continous signal is being recd from the sustain pedal( even with a different Sustain pedal)
    2) I have tried the same with a different power cable and after re-setting the device.

    Since the pedal was working fine earlier and suddenly this issues is observed and all other keys are working properly. I am suspecting a hardware issue with the sustain pedal input.

    Requesting you to please guide me further to troubleshoot the same.

    Thanks

    Arjun
