I’m concerned

Pitch Bend is not bending

I have an Alesis VI49 keyboard. When I move the Mod wheel, or other assignable knobs I see numeric changes on the blue 3 digit readout. When I use the pitch bend wheel there is no change and I get no pitch bending when controlling synthesizers with the Midi out. Is this a hardware failure or something I can enable

  • Hi Bill,

    Thanks for posting. 

    Do you notice the modwheel is not functioning when used with a computer and DAW, as well?

    Let's have you try a MIDI test so you can see what MIDI data (if any) is being sent:

    Windows Important: Please close all other Audio/MIDI software before running this test. Other software may interrupt or conflict with the results of the test.

    1. Download and install MIDI-Ox from the link below:

      MIDI-Ox 7.0.2 7.0.2 (Use the download link for MIDI-Ox 7.0.2)

    2. Run the midioxse.exe file to install the software. Follow the on-screen instructions. 

    3. Open MIDI-Ox.

    4. In the window that appears, select Options > MIDI Devices

    5. In the MIDI Devices window, click on the ports for your keyboard or MIDI device in the MIDI Inputs and MIDI Outputs sections. Make sure that other device remain unchecked so that you are only viewing the response from the device in question. Click OK once selected to close the window.

    6. To test the keyboard or MIDI device, simply press keys on the board or send MIDI data through the interface. If connected and communicating properly, the incoming MIDI data will be displayed in the window:

      USB MIDIox

     

    Mac OS X Important: Please close all other Audio/MIDI software before running this test. Other software may interrupt or conflict with the results of the test.

    1. Download and install MIDI Monitor from the link below:

      Snoize - MIDI Monitor

    2. Double-click on the .zip file that downloads and run the MIDI Monitor software inside.

    3. Click on the arrow next to Sources and check off the boxes next to MIDI Sources and the ports for your keyboard or MIDI device. You may want to make sure that other devices are unchecked to ensure that you are only viewing the response from the device in question.

      USB MIDISource

    4. To test the keyboard or MIDI device, simply press keys on the board or send MIDI data through the interface. If connected and communicating properly, the incoming MIDI data will be displayed in the window:

      USB MIDIResponse

     

    What does this mean?

    If data is displayed in the MIDI monitor:
    This is usually a good sign. This means that the device in question is communicating with the computer in some way. If the device is still not communicating with your software (i.e. a MIDI keyboard will not trigger a virtual instrument or respond in your DAW) this will likely indicate that software settings have become mis-configured or were never set up properly. In this case, you will find setup guides for a variety of products and software on this site. Search by brand and product at the top of this page to see if there are any guides available here. 



    If only some data is displayed in the MIDI monitor: A common use for the MIDI monitor is to determine if certain parameters on a MIDI keyboard are responding correctly. This may be because only some of the keys, knobs or other parameters are not communicating with the software, or because they are communicating incorrectly (i.e. sending the wrong notes or CC data). For example, if some of the keys work in the software and others don't, it may be a good idea to test if they respond with the MIDI monitor. If not, this could indicate a problem with the hardware.

    If no data is displayed in the MIDI monitor or the device is not available as an input source:


    This could mean that the device is not communicating properly. Make sure to try the following:

    • Try a different USB cable and/or USB port on the computer.
    • Refer to our Troubleshooting Class-Compliant Devices guide to ensure the keyboard or device is being recognized correctly by your computer.
    • Go through the instructions again to ensure that the MIDI monitor has been set up properly and the correct inputs are selected.
    • Select all available input ports for your device in the MIDI Inputs or Sources section. Some keyboards may have several ports that are made available in the input section which are used to send different types of information. For example, keyboards with Mackie/HUI functions will need an additional port to communicate this data. Make sure that all ports are selected as an input so that all available communication from the device is displayed.
    Let me know how this works out for you.

  • Wow Bill thanks,

    I am somewhat baffled by this. After reading your suggestions and connecting to a piece of software called " Midi Monitor " and tracking the messages I could see the Mod Wheel and the Pitch Bend wheel commands both coming through correctly.

    Then after this, I connected to some VST synths (ones that had NOT been responding to the Pitch Bend before) , and Viola!! the Pitch Bender works!

    No problem, just a wee bit baffled as to how just reading the commands changed things. Thanks so much for your help.
