Windows doesn’t recognize MOD as you plug it
Certain Windows systems don't recognize the MOD as a network device or fail to find the correct driver.
Use this driver for such cases: https://modclouddownloadprod.blob.core.windows.net/shared/mod-rndis-driver-windows.zip
For more information and to learn how to install the driver visit Troubleshooting Windows Connection.
Can't connect to the Web GUI (HTTPS warning)
When you are connecting to the MOD device for the first time through a web browser, the browser might try to use an HTTPS connection.
The connection to the device is a local one (which means that doesn't require an internet connection to access), thus the communication cannot be encrypted through the usual means.
Basically, HTTPS will not work and this is completely expected.
So if/when the web browser complains about the connection being non-secure, this is normal and expected.
Can't connect to the Web GUI in macOS
If you are not able to connect to your MOD device using Mac OS, please check Troubleshooting Mac OS Network
MOD does not boot, stuck on 'MOD Duo' screen
If the unit becomes unbootable for some reason, we might need to reinstall the OS inside.
We can boot the unit in recovery mode for safe reinstall, boot over USB if recovery partition is broken, or perform a full factory reset (which will erase all your data).
For more information see Troubleshooting Reinstall.
Note that the MOD Duo is not software brickable, you can always reinstall its OS.
It is possible to make the MOD Duo X unbootable though, if the bootloader or restore partition are corrupted.
The only way that can happen is if you remove the power supply during the very small period of the software update when the bootloader and restore partition are replaced, or if you intentionally break them.
In such cases it is still possible to recover data, but one needs a imx8mq developer kit in order to boot a custom image/payload (which the MOD team has).
MOD produces a lot of noise when plugged in my current setup (Ground Loop)
If you use other equipment along with your MOD and it starts producing loud noises when plugged in, you might be experiencing a Ground Loop. This could be other pedals, an amplifier, or even your computer.
In short, ground loops may occur when you have multiple audio equipments grounded to different power sources but connected between each other. This situation can happen with MOD Duo X because it is a device that is actually referenced to earth.
To check if that is the case, try to isolate the power of your MOD device and see if it changes your results. One thing that helps is to make sure your MOD device and all other equipment are connected to the same power socket.
Another way these ground loops can occur is by connecting to a PC or laptop which has a really bad power supply, so try disconnecting it from the PC.
References on Ground Loops:
MOD Duo X screens freeze
If your Duo X unit's screen stops operating properly (basically frozen) after a few minutes of usage, please try disabling the audio peakmeter service (in the advanced settings of the web GUI).
Use the advanced settings to trigger a power off of the unit, and then manual turn off and on the power again.
If this indeed fixes the screen freeze issue, please contact support to get your unit replaced.
If the issue is not fixed, try enabling the workaround to automatically restart the screen (also in the advanced settings).
Please post in our forums if you need to do this, so we can fix whatever causes it.
Failed to connect to MOD Cloud
If you see the "Failed to connect to MOD Cloud" message, you should try the following:
- First of all, double-check your internet connection
- There have been reports of some browser extensions that might prevent the MOD Web GUI to connect to the cloud. Try deactivating some extensions. One extension reported was the "Firefox Privacy Badger". Do you know any other extension that is causing issues? Please share with us!
Using Firefox and 'noscript' add-on prevents loading of cloud pedalboards
Open noscript preferences, then go to the advanced tab, then 'ABE'. The system ruleset should look like this:
# Prevent Internet sites from requesting LAN resources. Site LOCAL Accept from LOCAL Accept from http://integrate.moddevices.com/ Deny
Note the new 'Accept from ...' rule. This makes noscript accept requests from cloud pedalboards into the local network.
Dealing with noise issues
It is common nowadays in modern music setups to have noise issues that require some thought and experience to sort out.
If you are experiencing noise issues on your setup we recommend you to check the following aspects on your setup:
- Gain staging: check the gain levels both on the input and on the output of all of the devices in your setup;
- Pedalboard: check the effects on your pedalboard (both virtual inside your MOD Device or other physical devices in your setup) and pay attention for potential sources of noise;
- Ground loop: check for potential ground loop issues in your setup. Multiple grounded devices in your setup may generate noise issues.
For more detailed explanations and info, please check the "Dealing with noise issues" page.
Device loses USB connection when the host computer gets in sleep mode
If your host computer goes to sleep mode while your MOD device is connected to it, you may lose the USB connection to that machine. As a consequence, you stop being able to access the WebGUI.
The cause for this behavior is the "USB selective suspend feature" of your host device.
In order to solve it, there are three options:
- After the host device wakes up from the sleep mode, unplug and replug the USB cable between the MOD device and the device. This will re-establish the USB connection;
- Set up the host device so that it doesn't automatically go to sleep mode. Apple - which devices we received reports of this situation - recommends this solution when looking into their forums;
- Depending on the OS of your host device, you can disable the "USB selective suspend feature" for individual USB ports in system settings. However, if you are using an external USB hub (for example, if there is only USB-C and you need to place an external hub), you can't make use of this feature.
