I found I got best results using two identical EQs in series per neighbour track (2 tracks in total, making 4 bands of EQ), using the spectrum analyser in my DAW to make sure I was getting at the right frequencies.
I also found it very nice to set up scenes for each vowel sound and morph between them!
When setting this up, I have the Q value of the EQ set to 127, to get those sharp boosts that make up the formant filter.
The source material you are working with will have a big bearing on the effectiveness of this. Preferably it will be something that has a lot of upper harmonic material. With this in mind it can be a good idea to put a LOFI effect before your EQs to add harmonic material.
Try resampling the formant sounds you get and repitching them etc etc, have fun with it
it’s one of those classic timeless images, like that one of the big pink sunset, cheesy & comforting & nostalgic all at the same time, so if this doesn’t cure me then i’m afraid nothing will
Hi. I hope you feel better.
I had very interesting results with your informations, thanks. I found that Q could be lower. I prefered to have 4 different eqs per tracks, then copy track for neighbor.
One track is almost enough.
A saw wave seems better.
I made scenes, and modulated them with random lfos with midi tracks (CC55-56), and used a random speed modulated tri lfo for the CC48 crossfader.
As filters have 2 Q res + Env, I think it’s possible to have better results with them. In order to save tracks, maybe you can use only 2 frequencies.
It is still better with 4 frequencies.
With filters only you need 2 tracks if you want 4 fqs, with 2 Thru or 2 tracks playing the same sample :
T1 > F1 F2 (+ FX2)
T2 > F3 F4 (+ FX2)
I found interesting to use filter AND eq, in order to use only one track, and be free to chain 2 FX with a Neighbor track :
Filter > F1 F4
EQ > F2 F3
If you place filter after eq, it seems to sound the same.
It sounds different with the filter, especially because of the bandpass. 24db settings accentuate the bandpass.
You can thank @sleepystevo!
I can’t remember if I wrote frequency values somewhere. IIRC someine made a sheet with OT filter values and corresponding freqs…
. I’m starting to explore the OTs a bit more, cherry picking some of your crazy initiatives
