Tantra provides a high-quality, analog-modelled multi-mode filter section with
basic and advanced types of filters
There are 3 serially connected filters available for processing. The Multi-mode
filter allows you to choose one of the 18 modes with the Filter Type control:
• Clean / Dark LP/BP/HP. New filter models in version 2.x, Analog-
modelled, zero delay feedback filter with 12 and 42 dB slope
• Legacy LP/BP/HP 12 and 24 dB. Filter models from Tantra version 1.x.
Analog-modelled filters, with high-quality internal saturation stage and
12 or 24 dB slope
• Phaser 4p and 8P. 4 and 8 pole phase filter. The filter passes all
frequencies through the output, but alters their phases. The filter can
be used for designing phasing eects
• RingMod. Ring modulator, multiplies the input together with a sine
wave. Useful for creating metallic sounds as well as weird or unusual
tones
• PitchShift. Frequency shifter, which allows you to alter the pitch of the
incoming signal. Useful for making pitch-slide eects
• OctaveBand. Bandpass filter with an one octave passband width.
Useful for making voice and robotic kind of sounds
• Vowel. Special filter type intended for producing vocoder-like eects.
The filter emphasizes frequencies around the points, called formants
The Cuto and Resonance controls allows you to adjust the filter’s frequency
and resonance respectively. The output of the Multi-mode filter is processed
by a serial chain of additional Low Cut and Hi Cut additional filters. These
two filters can be used for designing creative open-close kind of eects
independent of the main filter.
