Issue routing Input Ring signal in Simple Mode
This could be due to the experimental Input Split feature that was added in the ML10X rev-b firmware and may have been enabled by default in some batches.
This feature allows you to run a stereo signal in Simple Mode with a mono input (Input Tip) by splitting the Input Tip signal into 2 and discarding the Input Ring signal.
This feature can be turned off. In the ML10X menu, go to Global Config >Set Input Split and then select Input Ring.

Problem
If you find that PC or CC messages are working when controlling the ML10X, but the ML10X message type is not working, it is likely because there are MIDI device inbetween the MC and ML10X that are not passing SysEx messages through. For example, the HX Stomp does not pass SysEx through, so if you have a MIDI signal chain like this:
MC6 >HX Stomp >ML10X
The ML10X is not going to receive any of the ML10X messages from the MC6.
Solution
Connect your ML10X directly to your MC.Few readersTesting the MIDI Input on the ML10X
To test the MIDI Input on the ML10X, you can make use of the Test Function in the device.
Press the menu button and navigate to Enter Global Settings
When in the Global Settings page, navigate to Test Function and select
There will be a series of tests available. You can just press the left (back) or right (forward) arrow to go through the tests. Press the right arrow until you see Test MIDI Read.

Troubleshooting your ML10X connection issues
Are you having trouble getting sound in and out of the ML10X? This troubleshooting guide will help you determine whether you just need to get to know the ML10X and its settings better, or whether you're really dealing with a hardware or software problem.
Firmware and the Editor
As of July 2025, if you're primarily using the "Simple Mode" of the ML10X, then your best bet is to use Firmware v1.1.2 (https://github.com/Morningstar-Engineering/MLFew readersML10X Audio Issues
If you have an early ML10X unit and are having audio issues, there is a possibility that a connector might have come loose due to the unit being dropped.
You can resolve this by removing the backplate and checking the connectors if they are loose, and pushing it back to secure itFew readers

Using Mono and Stereo pedals together
There are several possible scenarios when using Mono and Stereo pedals together.
Splitting a mono signal within the ML10X and routing it to a stereo pedal input.
For any splitting or merging of signals in the ML10X, only Advanced mode can be used.
For example, if you have the Strymon Sunset (mono) and the Strymon Timeline (Stereo) device in your setup, and you want to split the mono signal from the Sunset and run it into the Timeline stereo L and R inputs, the setting will look like thisFew readersEngage/Bypass Loops in Advanced Mode
Overview
Consider this connection:
When A Tip is bypassed, the connection will look like this:
Pretty straightforward stuff. The complication arises when the signals split and merge.
Consider this slightly more complicated connection:

If you want to use a Mono Input / Stereo Output pedal with the ML10X, this article describes how to do it.
We will use the Chase Bliss Mood in this example, which has a Mono Input and a Stereo Output.
You will need to utilise an additional loop for the Stereo return. In this example, the cable connections are as such:
Guitar >ML10X Input Tip
ML10X Send A Tip >Mood Input
Mood Output Tip >ML10X Return A Tip
Mood Output Ring >ML10X Return A Ring

Yes, it is possible to use multiple ML10X with a MIDI controller. There are a total of 16 MIDI channels, so if you want to control each ML10X independently, then you can set each ML10X to an independent MIDI channel (i.e. ML10X-1 on Channel 1, and ML10X-2 on Channel 2), and then send the PC/CC messages on their respective channels to control each one independently.
If you are utilising the ML10X message type from our MIDI controllers, you can use the Device ID to differentiate each ML10X.
TheFew readersWhat voltage to run the ML10X on?
The ML10X can be run on voltages ranging from 9v to 18v. For most cases, running 9v is enough, which gives you a 4v peak to peak handling level. Running on 18v gives you 10v peak to peak. If you are not handling a very hot signal, and do not notice any clipping, then running on 9v is fine.Few readersUsing Advanced Mode in the Editor
In the ML10X v1.2 update, we have enhanced Advanced Mode to allow the engage/bypass of loops. In the editor, each loop will now show a Green or Red shade to indicate if it is Engaged (Green) or Bypassed (Red) when the Preset is loaded.
In the editor, to toggle each node between engage and bypass, you'll need to DOUBLE-CLICK on the node.Few readers
