X Touch One - MCU and VST plugins

Hello guys,

I’m posting this because I need some clarification on VST plugins and X Touch One. I use Cubase 13 and my X Touch One works as a Mackie device right out of the box. So, no complaints here. Recently, I’ve started seeking to map some plugins since, in situations where the plugin prevents me from typing the value, I require greater precision to configure it than to try and match it with my mouse. So, I can control some buttons but not the fader with my custom surface and MIDI Remote. This is due to what I assume to be conflicts with the MCU. I was unable to make the controller operate as a MIDI remote to stop using MCU. Neither the MIDI mode nor the MIDIRel work. The issue is well known. As a result of everything previously stated, I’m searching for any solution that will allow me to set a plugin’s fader using MIDI Remote Surface without having to go too far into MCU coding.

Has anyone figured out how to temporarily disable the MCU when using a plugin, or how to switch between the MCU and MIDI Remote?

you probably need to set the X touch to ‘user’ mode first and that will allow you to program it how you want.
Which mode are you using at present?


Hmmm… my understanding is that the user mode still is MCU. I use pre-defined MC Cub mode.

Page 54 of the official manual is clear about the user mode, it is Mackie. I tried Nr and NI modes with no luck.

Prior experiments revealed that the fader functions by transmitting a ‘Pitchbend’ message on a channel that is currently in use, allowing a VST plugin to detect it when assigned. However, this message obviously interferes with the fader’s present location on the channel.

If the VST plugin was being used, I wish there was a way to turn off the MCU.


For everyone who is interested in this topic. Eventually, I got it to work. The X Touch One needs to be added to Cubase as a Mackie device and in MC Cub mode. In this mode, every feature presented on the Cubase template for the device functions as intended. Make sure the MIDI ports are assigned appropriately as well.
Based on the specifications given in the official device documentation, design the surface that best fits your needs. Next, tap the device’s Master button. At this point, Cubase will automatically produce two knob controls when you touch and slide a fader. A pitchbend control is one, and a touch control is the other.
Choose Plug-in Window Focus Only under the Quick Control Focus options. You can now begin mapping plugins. Simply press the master button to enter master mode, which releases the fader control for your use, to use the fader with plugins. That’s it.

To illustrate, I set up an EQ plugin, which has several fader controls, by making several pages, one for each fader. Additionally, I assigned the F1 and F2 buttons on every page the Next Page and Previous Page functions. This lets me navigate through fader controls on the plugin. Multiple plugin faders can be controlled by a single fader device in this manner. Remember that every control assignment has two focus options, so make sure to make it global.
