Hi , i have tried to use the Mods, Distortion & overdrive & saturation, to actually make a real dirty Fuzzy Overdriven sound/DistrotionBox, but it dosnt happen, all that seems to happen is ,the amplitude increases? is there already a Fuzz box/Mod out there, i am willing to attempt to build one myself,,,but the truth is,iam not really sure where to start, if one of you kind people will just point the way , thanks Jamie aka Mad_ManX............ 😇

In it`s simples form an Overdrive is yust a clipped increase in amplitude. This will give you those nasty square waves. A typical fuzz, in conventional electronics is done with a diode or a transistor. Where the characteristics of the sound are due to overloading a transistor "or diode". Wich in our non perfect way of doing things has a typical sound per component. To mimmic this you can look at the difference of the sound coming out and going in and derive a mathematical formula to change the sound in the same way.

But since I assume you want the easy answer, check the search box for transfer curves, tubes, and oh yeah also check for Twelve AX7 <-- 🙂

Haaa, thank you very much for your pointers, MegaHurtz 😇 , i did have to read over your comment 2 maybe 3 times before it slowly started to make sence, & i do understand the princaples of distortion, or more over FuZZ, actually you could say that Distortion as a defined Cold sound to its nature ,due to its agressive breaking up of the signal ,where as Fuzz as a Warm sound its nature, i think thats becuase there seems to be more of a saturation fx,,, with FuZZ. ? yeh Thank you very much for your Reply . Jamie. aka Mad_ManX 😉

Yes it`s correct to say it`s due to the satturation.

Twelve AX7 , i opted to download it, 😀 Thanks again MegaHurtz... 😀 its for a New D&Bass Synth, that i am putting together, from bottom up ? all based on the Ree's sound ... lol so i needed a good Distortion/FuZZ_Box.... 😉 J/MM.

you also could checkout andrews oversampling toolkit at the wiki. for a nice sounding distortion (..saturation, whatever you call it) there will be additional harmonics higher than the original ones, so you usually hit the nyquist pretty fast and if the frequency overshoots your half samplingrate then it gets mirrored back down which in most cases sounds distorted in a very messy way.

Personally i would say if your making something based on Reese then just distort the samples before you use em in a wav array Because you need to do the pre sampling of detuned saws to get a good Reese I'm open to offers here but i have never ever heard a Reese that sounded good unless it was sampled and resampled Somebody please prove me wrong (I would love to see how they did it, so i could try it myself )

Yeh cheer's Michael, i will check that OverSampling kit,its actaully a very controlled Distortion/FuZZ i am after, fully controlable to the point of heavy saturation, & of course avoiding any kind of clipping? which i myself feel it,s what leads to Cpu spiking & dropouts?

Hi Nas... please forgive me dude,, but all this is so new to me,,, even your first line left me behind? {then just distort the samples before you use em in a >>>{{ wav array }}<<< Now i am lost, 🙁 Remember the noise that "Omar Simpson" makes when its somthing he dosnt understand..... dohhh 😉 going back to what you said tho Nas, Surley just detuning form 3 Osc's all Saw of course, 1st one being the root ? & clever use of Low & High pass filters & a distortion, are you telling me a Reese can not be acheived with those elements ? 😉

worth a try 🙂

If you want it to be a drum and base synth, the twelve ax7 rules.. i think. Becouse it`s assymetric it keeps the top half of a sine like a sine and the bottom half is clipped. So it preserves the base, gives an equal amount of clipping to it AND 😀 It creates a harmonic thats an octave lower than the fundamental freq. so it creates some lower base aswell. (all assymetric distortions do) Id say totally the right distortion for the yob.

also if you put the "tube" after your volume knob, the change in volume affects the dynamic range. So it gives ability to change the sound a little bit. By tweaking the gain.

Cheers!

It sure is Nas,,, but did you say that with Tounge in cheek ? lol 😉 ,,, i will look into your theory of placing the resampled Saw's in the Wave array,,,,, i cant believe i just said that line, geezz iam turning into a geek. lol 😈 haha only kiddin sir,,, Jamie aka Mad_ManX:)

Thank you MegaHurtz...Thats very interesting , It creates a harmonic thats an octave lower than the fundamental freq.Hmmm sounds very interesting, i wonder can this lower Harmonic/Octave be seperated @ all , or at least be controlable, perhaps with amplitude, ? i dont know, is that a silly question ? 😊

MegaHurtz ·

maybe interesting to see what happens if you subtract the original from the distorted. I dont know if it`s any good really?

No it's always worth a try You may have better results than i have The only way i could get what i personally would call a good reese with pure synthesis used so much CPU it was near unusable compared to just resampling But that may well have been my lack of skill more than anything else 😉
