Filterbank
Seven new filter effects added to the re-branded Filterbank (formerly called Freq. Shifter) alongside the previous Ring Mod, Freq. Shifter, Comb and Vowel filters.



These comprise of three new LP, BP and HP 'VariSlope' filters, each allowing you to seamlessly morph from 2- through to 6-poles for gentler or steeper rolloffs respectively, offering additional control over the curve at the cutoff frequency itself, hence 'variable slope'...

.. and four additional new 1-, 2-, 4- and 6-pole 'XFade' (aka cross-fade) filters, each allowing you to seamless fade between low-pass through band-pass to high-pass filter modes.
