Phase Distortion Thread

[tconrardy]

Hi all

Since the release of the M51, which is primarly a Phase Distortion ( PD) Synth, it may be that there are users who don't really know WHAT PD IS!! myself included.

To get started, here are some excellent links

Phase distortion Theory

http://en.wikipedia.org/wiki/Phase_distortion_synthesis

Programming CZ synths

PD Synthisis with audio examples

The last link is pretty good.
Basically it seems like PD is like FM, but uses a wave to distort a sine wave into other kinds of waves. In M51, we also mimic the types of waveforms that were present in the CZ series which included some "res" type waveforms with resonance built into them.

also, if you use an envelope to shape the wave, it's like the sound of a filter opening and closing..so thats why there were no filters in a PD synth. You use an envelope to alter the Timbre.

any more thoughts from you guys??..this is just a prilimary from me.

Thanks for the post I was aware of P.D synthesis before this, but had neglected to do any research into it. It seemed like another also ran that never got anywhere.Increasingly I have noticed a number softsynths featuring it as there primary synthesis method, so these articles will be of great use.

FYI: We're working on small paper that will cover the basics of PD synthesis, so stay tuned!

The greater part of the tutorial is uploaded.
Enjoy!

This tutorial the dr is working on is great! One of the best I have seen on PD synthisis..CHECK IT OUT!!

thx Tim...

What's kinda odd, is that I developed something like this myself a couple of years ago without knowing the history. I've called it skew modulation, since the wave get's skewed one way or another. I have some variations on the basic algorithm, but there it is.. nothing new under the sun and all that!

nice lynx, tvm!

(*) Yamaha's implementation of FM was actually phase modulation, which is also what phase distortion is)

ooh, nasty hack you have there 'byt - you got health modulation problems?

I had atan from the summer, but it's phased out now. We could go the whole hog for phrase distortion, should we wish.. :hihi:

btw what kind of viable hybrid are we talking?

Looks like there's some serious phase confusion going on here...
