Can it be done? I'm new to the whole thing and I mostly want to make fx for my guitar parts. I tried just putting a multiplier on a signal but that just pushes the volume to clipping in the whole track. I was looking for a way to limit the overall signal while still distorting the waveform so I could have distorted but quiet sounds. Can SynthEdit do that? Newbie looking for help so thanks in advance.

Can it be done?

A simple way, use a waveshaper 2 and use
tanh(x) to "shape" the signal....

Try a Waveshaper2 module after the multiplier.

Alternatively, search the net for distortion modules:

Dave Haupt made a great soft distortion module for example..

I am yet to find a decent sounding distortion for SE. Using a Waveshaper sounds horrible and Dave Haupt's module, whilst it sounds alright, doubles the CPU usage of a synth whenever I use it.

two level adjusters and one sv filter can do wonders here

what about this ... just an idea...

BONES, try this:

Signal -> Multiplier (input2 = distortion amount) -> Waveshaper2 {equation: 5*tanh(x)} -> MoogFilter -> Container

into Container:
Signal -> SV Filter (bandpass, 3.3KHz, resonance 7)
Signal -> SV Filter (bandpass, 180Hz, resonance

both SV Filter outs get mixed together to the output
and to an AllPass Filter (resonance 10)
AllPass Filter (which is in parallel with the SVF's) to the output

Adjust AllPass Filter's freq from 0.1 to 5 for a cabinet emulation

More complex cabinet emulation can be done with some more SVFilters and Allpasses

I imagine that would be rather expensive CPU wise for just distortion.

I've been interested in a good distortion module for a while too as I'm working on a synth for DnB bass, and I'm gonna put adjustable distortion before the ADSR's.

This design does distortion plus cabinet simulation.

Right-O. nevermind then.

Cabinet simulation or not, that would more than double the CPU usage of any synth I've made. I think its much easier to add a distrotion VST in an insert slot in my host. But thanks for the info, it looks neat.

Now that sounds f**king awesome! And it only adds about 1% to my CPU. Nice GUI too. I assume you don't mind if I use it in my new synth?

One thing that occurs to me is that I should put it outside the main container with the polyphony at 1. That might solve a lot of my CPU issues.

a simple -ceil- can do it to in -math-

BONES quoth

That would be more typical, yeah. Per-voice distortion certainly isnt that common, unless you're looking at it more from a 'waveshaping' point of view. But the distortion should be more harmonically consistent with the notes being played. In contrast 'final-stage' distortion (ie outside the individual voices) probably introduces more inharmonics.

You could, if you wanted, make it switchable, I guess, as long as the distortion stage sleeps properly.

of course not, just go ahead

Create VST Distortion in SynthEdit?
