CV Tutorial

This article will show how you can use CV with your MOD Device.

Although only MOD Duo X has CV input and output, you are still able to use CV signals inside your pedalboard with any MOD device.

Getting Started

Choosing input mode (Duo X only)

There are two ways in which you can use the CV/EXP input:

• CV: Use it as a CV input. Duo X CV input/output is unipolar positive, which means it reads/sends signals from 0 to 10V.
• Expression pedal: Use it with an analog Expression pedal.

These settings can be found under "System > Inputs" in the Device Settings menu.

Note: When using an analog expression pedal, you might also have to adjust the "Expression pedal mode".

Note: The Duo X initial batch units use 5v on their inputs and outputs, even though the values 0-10 are used inside the pedalboard. Second batch Duo X units (and later) use 10v both in hardware and software though.

Inputs and outputs on the UI

In the UI, CV connections are represented by orange cables.

ON Duo X, you will see three extra inputs and two extra outputs in your pedalboard.

The top two CV inputs are the two CV inputs available when you plug in a TRS cable with CV signals.

The bottom CV input is actually the Expression Pedal input.

Which of the input ports are available will be defined by your Input settings

As any other connection in your pedalboard, CV connections can be split and merged any way you like.

Basic usage

Snapshot of the Plugin Store's CV category

There are many CV tools available in the Plugin Store to use. There are LFOs, Envelopes, VCAs, tools such as switchers, audio and MIDI to CV converters, and many more.

The possibilities are endless. Here are some examples of CV Basic usage:

Example 1 - SCREENSHOT - using an external CV controller (maybe simulating receiving a signal from a CV keyboard?)

Example 2 - SCREENSHOT using only CV internally to produce some sound

Example 3 (optional - something more unusual)

Using CV signals to control any parameter on your pedalboard

We can also use CV signals internally in our pedalboards to control any parameter of any plugin!

Let's see how to do this.

1. Enable the CV port you want to use

Click the "Manage CV Ports" button at the top of the screen:

When this button is active, you will notice that a white checkbox will appear by each CV output of all CV plugins:

When you click any of these checkboxes, you are enabling this output to be used as a signal source to control other plugins' parameters.

For this example, let's enable the LFO output:

Notice that when you enable a port, you can assign a name to it. This will make it easier to find it later when using this port to control a parameter.

2. Assign

Now, let's use the wave signal generated by the LFO to control the Depth parameter of the INVADA Delay Munge.

Open the plugin settings and click the "assign" button for the Depth. This is the same procedure you are already familiar with, used to assign parameters to external controllers.

Now in the "Assign" dialog, choose the "CV" tab. You will find all the ports you enabled in the list to choose from.

Note: Duo X users will also see physical inputs 1 and 2 as options to assign the inputs directly to this parameter.

Now we can see the result. The Depth is oscillating following the signal generated by the LFO.

3. Advanced Settings

Back to the "Assign" dialog, if you click the Advanced button, you will see a couple of additional options to give you more control on this assignment.

• Range: Set the range that will be affected. By default, this brings the full range the plugin accept, but you can change it
• Operational mode: Indicates what values this parameter expects from the CV source. This is automatically detected and, in most cases, you don't need to touch it. However, for more complex CV setups, you might want to change this.

Still using our original example, we changed the range from the default 0-100 to 30-70, and this is the result we get:

As you can see, now the full range of the wave generated by the LFO acts only in the defined range set in the Assign dialog.

Using CV Parameter Modulator

As you saw, it's easy to assign a CV signal to a parameter.

However, it might be hard to find the tune you want by tweaking the "Advanced" options to change the range of the assignment. Having to open the dialog and typing the numbers by hand takes time and it's not as organic as we like things to be making music.

That's why we prepared the CV Parameter Modulator plugin.

With this plugin, you can modulate and prepare the CV signal before it is sent to control any other parameters.

Following our example, let's:

• Add the CV Parameter Modulator to our pedalboard
• Connect the LFO output to its input
• Disable the LFO output port and enable the CV Parameter Modulator output port
• Change the assignment of the Depth parameter to the new enabled port

As we can see, CV Parameter Modulator has two parameters:

• PARAMETER: This defines modulates the signal coming in and sets its center value (IMPROVE THIS DESCRIPTION)
• MOD. DEPTH: This defines how much the input signal will be multiplied. If this parameter is at zero (center), the output will always be zero.

One of the biggest advantages of using this plugin is that you can also assign these controls to physical knobs and tweak it from your device.

Now let's have a look at how is our result if we set the PARAMETER to 70% and the MOD. DEPTH to a small number, close to 10%:

As you can see in the animation above, the end result shows the assigned parameter centered at 70% and oscillating a very little range.

Now, let's increase the MOD. DEPTH to something close to 90%:

As you can see, the Delay Depth still centered at 70%, but now it's oscillating much more.
