Using a MIDI Monitor to Test a MIDI Device

other class compliant usb icon3A MIDI Monitor is a useful tool to quickly test if a MIDI device is properly communicating with the software. This may be useful if a MIDI keyboard or interface is either communicating intermittently (i.e. a few keys on the keyboard have stopped working) or not at all. This guide discusses one way to quickly set up and test the device.

  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.

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 you do not see one available, check with the software developer to find available setup guides or tutorials. 

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 the keys or parameters are not responding in the MIDI Monitor, or are responding differently than expected (i.e. different MIDI channel, wrong note or CC data) refer to the User Manual for the product and contact Technical Support for further assistance.

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.

If you are still having trouble and not receiving any response from the keyboard or MIDI device, contact our Technical Support for further assistance.
