Formant Filter shapes the sound in a similar way to how the vocal tract works, leading to vowel-esque sounds. It will boost two frequencies to mimic the sounds of different vowels:
- Vowel Selector - Selects two frequencies to boost. We've put the phonetic symbols of some common vowel sounds on the selection pane. (Honestly that doesn't help much. I have no idea how ɤ sounds anyway.) Applying a LFO modulation to either axis of the pane can give some nice human-esque qualities to your sound.
- Q knob - Adjust how powerful and narrow the frequency boost is.
- Lows - Allow low frequencies through the filter.
- Highs - Allow high frequencies through the filter.
- Settings panel - Whenever you have your mouse cursor over a snapin theree is a small arrow at the top right corner (not visible in screenshot). It opens a settings panel where you handle presets.
- Enabled checkbox - The small checkbox to the left of the plugin name is a checkbox that bypasses the effect when disabled.
- Resize handle - The bottom right corner of all Kilohearts plugins is a resize handle for scaling the UI to any size. This allows you to get a good view of the controls whatever the screen resolution, and also comes in handy if you need big controls, e.g. when using Formant Filter as a real-time effect on a touchscreen monitor during a live set. (This is not available when the snapin is used inside a snapin host.).
Formant Filter shines on it's own, but it was primarily created to power up the different "Snapin Hosts" Kilohearts offer. These are bigger effects units that utilize all the available snapins and give you a really fun and creative workflow for combining them in any way you can think of. So have a look at Snap Heap and Multipass right now.
Formant Filter is also available as a Rack Extension for Reason over at the Propellerhead shop.
