When sending a Neuro Mobile App message, does the control input LED (towards the top of the pedal) flash in response? If not, check that the mobile device's volume is set to 100%, and the 1/4" end of the TRS cable is going into Input 2 of the pedal. If the control input LED still does not blink, or it blinks but no changes are made, use a lower volume (40-95%).
​
Any progress? If not, unplug the 1/8" end of the TRS cable from the mobile device, and send any Neuro Mobile App message. Is there a burst of white noise? Please ensure the headphone port of the mobile device works by plugging in headphones and listening at a low volume level. Do not listen at high volume, it will be LOUD. Also, ensure that the mobile device is not applying filtering to the audio signal (3D-ify, Bass Boost, etc...). If the mobile device is in a case, confirm that it is not obstructing the audio cable from being plugged in completely.
​
Certain mobile devices will swap left and right audio channels, or even invert the audio phase. This issue can often be fixed by going to Neuro Mobile App // About, and enabling “Invert Audio Output (advanced).” In some cases multiple changes are needed for the messages to be sent correctly. For example, the Android Honor 8 requires that phase inversion is selected while also reducing the phone’s output volume.

Side Note: The Neuro Mobile App has one-way communication; the pedal can receive messages from mobile devices, but mobile devices cannot receive messages from the pedal. Because of this, hardware and sound editor parameters will necessarily show the exact configurations of the connected pedal. For example, if edits are made in the Hardware Options menu, then the menu is opened later, the default settings will be shown. Not to worry, your settings have been saved to the pedal, despite the changes not being reflected on the mobile device. For two-way communication, use the Neuro Desktop Editor.

​The 1/4-1/8 inch Neuro that comes with the pedals actually does work for new iPhones, you just need that apple "dongle" which is a 1/8" headphone jack to lightning converter.  Here's a link to the device if you're not sure:

If you don't want to use one of these, the pedal can also interface with your desktop via a USB A - Mini B cable using the Neuro Desktop Editor (Download Here for Windows or Mac).

Please try the following troubleshooting steps:
1. Disconnect and reconnect the USB connection from your pedal to your computer.
2. Check another USB mini cable if possible.
3. Check for any USB Hub devices.  If you are using a USB Hub to connect your USB devices, try disconnecting it and using a direct USB connection to your pedal.
4. Try restarting your computer, as well as re-downloading the Neuro Desktop Editor from our Support > Editors and Firmware tab.
5. If none of the above steps prove successful, your pedal may need a Bootloader Reset.  Please contact us directly for these instructions.

Connect your pedal to the Neuro Desktop Editor (Download Here for Windows or Mac) with a mini USB cable
If connected properly, you'll see the pedal in the left margin in a blue box.  Hit the Gear icon right below.
This will open hardware options for your pedal.

The guide below will help you understand which Source Audio accessories (if any) are required to enable MIDI functionality to each of our One Series pedals. In addition to a MIDI controller and MIDI cables, some pedals require either the One Series MIDI Adapter or the Source Audio Neuro Hub. All of the pedals also respond to MIDI messages (to varying degree - see below) from a Digital Audio Workstation (a.k.a. "DAW") via their mini type-B USB port.
