Modor - New Eurorack Formant Filter // Synthfest 2017

"I think this went largely missed by many at Synthfest but the new Modor eurorack modular formant filter sounded great! Stereo formant filter coming from their NF-1 synth in modular ... yes please! Looking forward to seeing how this develops."

"We received the question quite a few times: 'When will you break up the Modor NF-1 in Eurorack pieces? Well, we 're not going to build Eurorack modules for everything there is in the NF-1, but we tought our formant filter is that special and unique we can't leave the modular world deprived of it ... :-)

So, here we are: Modor's Formant Filter in a Eurorack Module!

Modor's Formant Filter is a special filter that does a kind of 'vowel morphing' between three vowels. The big central FORMANT control is responsible for that, and on the Eurorack module there's of course a CV control (with attenuation) on this parameter.

You can imagine a formant filter as a set of parallel bandpass filters, picking up and amplifying a set of small frequency bands. For example, with these frequency bands around 750Hz, 1200Hz and 2800Hz, you get the sound of an 'A'. So far, nothing special. There are more formant filters around composed of a set of parallel bandpass filters.

It gets more interesting when you're able to 'morph' between different sets of those formant frequencies. Behind the central FORMANT control, there are 3 of those sets of frequencies. One at full left, one in the middle, and one fully right. So you can for example morph between A-E-O. Or U-I-E. Or AO-UI-EU. Or ...

That's what it does: morphing between different sets of formant frequencies, and that's why it sounds a lot more genuine vowelish than many other static bandpass combinators.

There are 10 preset vowels, that can be selected with the VOWEL button: A-E-O-I-OE-U-EI-EU-AO-U-UI. The vowels of the Dutch language... :-)

The 1-2-3-4 controls on top give you the possibility of composing your own vowels by manually adjusting the frequency bands."
