2.1 Maul Drive stages
Each of Maul's 3 drive stages features a very similar set of controls.
Filtering functions: Cutoff, Q, 24dB (all stages), Width (Mid stage only)
The filtering functions are available only in Multi (parallel) mode, and are used to determine the
frequency band affected by each drive stage. Unlike the Tone function described below, these
filtering functions are applied prior to the drive circuit in each drive stage.
If the Cutoff parameter is swept via modulation functions, a MIDI C C or host automation, the
drive stage effectively acts as a swept resonant filter with an overdrive section after it in the signal
path.
Each filter features a 12 dB per octave slope by default. This can be switched to a 24 dB per
octave response by activating the 24dB button.
Low stage: Lowpass
In the Low drive stage, the Cutoff control adjusts the cutoff frequency of a lowpass filter. The Q
control adjusts the amount of emphasis around the cutoff frequency.
Mid stage: Bandpass filter
In the Mid drive stage, the Cutoff control adjusts the centre frequency of a bandpass filter. The Q
control adjusts the amount of emphasis around the centre frequency, while the Width control
adjusts the bandwidth of the filter.
High stage: Highpass
In the High drive stage, the Cutoff control adjusts the cutoff frequency of a highpass filter. The Q
control adjusts the amount of emphasis around the cutoff frequency.
Drive Type
This selector allows you to choose between the 32 available
distortion algorithms, which are described in the next section.
Switch the selector to the 'Thru' setting to leave the signal passing
through the stage unaffected by the distortion circuit. The other
functions in the drive stage such as the Dynamics, Saturate and
Tone functions can still be applied.
Drive
The Drive control adjusts the amount of distortion applied by the
drive stage.
