Hey renoisers !
After a few more hours on it, I’ve improved the precision of the « aeiou » vowels and reduced a bit the required ressources.
Here’s the Easy Formants v2.5 FINAL 
it’s a 100% native, fast, and easy to re-use trick
Features
- optimized formants filters system
- high precision vowels (x2)
- a bit more CPU friendly (5% Faster)
- simplified keyboard based formants control
- improved file size (2K lighter)
- formants feedback control
- auto Q
- auto bot voice mode (robotizer)
- RExciter ™ powered

FAQ
How to install it in my own song ?
- Right-click somewhere on the Track DSP chain. - Select Device Chain => Save As… - Select your target directory and give a name to the chain. - It must have the .XRNT file extention. - Then when you edit your song, right click somewhere on your Track DSP tab. - Select Device Chain => Load… - Find your .XRNT file, load it. - That’s all. Yep.
What input sounds / samples does it require to work well ?
- SAW based samples (oblique waveform) with notes/tones within a range of 300 to 3400 Hz in the Renoise spectrum.
How to modify Formants ?
- Formants are « Keyboard Controled ». Both the Qwerty and the MIDI keyboard can be used. - Use the C-0 to D#1 Keys to modify formants while the music is played. - You can modify them while you record notes, or play LIVE, with your QWERTY or MIDI keyboard. - Go into the Sample Keyzones. - Modify your Sample Layer so that it doesn’t use notes from C-0 to D#1. - By this way you’ll be able to both play your sample & control the filter in the same track.
How exactly did you placed formants on the low notes ?
- Formants are composed of 1 cycle of ‘ieawyuw’ vowels fragmented in 16 different notes and subtle differences.
[indent]C-0 ==================================> D#1
i – y – e – ø – ɛ – œ – a – ɶ – ɑ – ɒ – ʌ – ɔ – ɤ – o – ɯ – u

- you’ve got to use your ears to know these vowels !
How to sound lika robot ?
- Completely drag the Humanize slider to the left.
I don’t like the robot sound. How do I delete it ?
- Drag a bit the Humanize slider to the right. - Or uncheck « Bot Voice »
What is the Feedback parameter ?
- This is something that adds some personnality to the sound. - Warning, too high parameters will produce a glassy/metallic effect, that is stange, but however interesting.
What is the Auto Q parameter ?
- The Auto Q parameter slightly increases the Q factor of bandpass filters when formants deal with higher frequencies. You can switch it off if you want to use the Bandwidth slider like a Wet/Dry signal slider.
My filtered sound is poor compared to yours.
- It’s logical. Some harmonics have been removed by the chain. Put the *Exciter DSP and the end of the road, and raise the DSP sliders to revive the original sound. - Try to use a SAW based bass samples, because it’s the closest from the male human vocal typical base waveform.
