Preset controls

Preset menu

This drop-down menu displays all available presets of the relevant type, arranged in category sub-menus, as well as the Save preset, Load preset, and Rescan presets functions.

Save preset

This function prompts you for a filename in order to save the current settings to disk. It is recommended that you save presets to the default folder that is shown so that they can easily be reloaded using the preset picker menu.


Load preset

This function allows you to browse to and load a preset from any location.

Rescan presets

The Rescan presets function scans the preset location for new presets you may have copied there since you launched Maul.

Reset to default

This function resets the state of Maul to its default settings.

Save As default

This function allows you to set the current state of Maul as the default settings, meaning that they are recalled when Maul is launched as a plugin and when using the Reset to default funtion.

Clear default

This function clears the current user-defined default if it exists, meaning that the factory default settings are used as the defaults.

Prev/Next preset

These buttons sequentially step backward/forward through the current preset category.

Drive stages


Maul features 3 Drive stages: Low, Mid and High. See the next section for full details of their operation.


Drive stage routing

Maul's 3 drive stages can be used in 3 configurations:


Multi (Parallel)

This is the default configuration. Each of the 3 drive stages operates in parallel on the input signal. Using the Frequency cutoff controls, each stage can operate on a specific range of the frequency spectrum.


In Serial mode, each drive stage operates on the incoming audio in series - one after another. The Frequency and Q settings (as well as the Width control in the Mid stage) are not available in this mode - each drive stage operates on the entire signal feeding into it.


In Single mode, only the Mid stage is operational - the other 2 stages are disabled. It operates on the entire frequency spectrum - the Cutoff, Q and Width controls are unavailable.

Modulation/Visualizer display

The Modulation/Visualizer display screen at the top-right of Maul's interface can be switched between 3 views.


The Modulation view shows the controls for Maul's internal modulation devices: 2 LFOs, an envelope follower and a sample & hold. The main parameters for these devices can themselves be modulated via the TransMod system.

Each modulation device features an individual Visualizer display. The nature of each screen varies according to the function of the module.



Clicking the Filters tab switches the display to Filters mode, which shows a representation of the filter responses of the 3 drive stages. A realtime display of the amplitude of frequencies across the spectrum in the processed output signal is overlaid on the filter response curves.



Click the Spectrum tab to switch to the Spectrum display. This view shows a 32-band graphic analyser of the frequency spectrum in the processed output.

Master controls

Out Gain

This control adjusts the overall output level of Maul, useful for attenuating the gain added by its drive stages.


The Mix control sets the balance between the original input signal (towards the left of the control) and the processed signal (towards the right of the control).


Activating the Limit button engages a soft limiter on Maul's output. Note that the signal can still exceed 0db if it contains very fast attacks.


The Master section's Saturate button activates a saturation circuit which is applied to the entire output signal. The saturation behaviour is dependent on the signal level. Note that this function is not a peak clipper - the signal can still exceed 0dB.

Hi Def

Enabling the Hi Def button results in processing audio internally at a higher sample-rate, minimising aliasing artifacts. The sound quality is better but comes at the expense of higher CPU usage.


Click this button to bypass Maul, so that the input signal is passed to the output unaffected.


This button activates MIDI Learn mode, which allows you to map MIDI CCs (continuous controllers) to Maul's parameters.

Options Menu


This function displays Maul's version number and credits listing.

Show MIDI Panel

This function allows you to set the MIDI channels used for MIDI note input in Maul.

Open manual

This function opens the Maul online manual in your OS's default web browser.

Check for updates

This function checks the FXpansion website for any available Maul software updates.
