[SE] Waveshaper2

[Kriminal]

after a recent msg i read i was wondering how its possible to use just one OSC and have if feed into several Waveshaper to creat diff shapes (from an original sinewave)

so, apart from manually drawing the shapes (i tried, itstedious and result are not great, but the basic idea work) i want to know where i can aquire the correct 'maths' to input into the waveshaper2 module

ie: sine>saw
sine>square
sine>triangle etc etc

thanks

(i did a google for this kind of info, but it was mainly dsp sites that wasnt specific enough for the simple 'chart' i was after, if such a thing exsists)

It's easier if you start with a saw wave. Sine is obviously sin(saw) and square is sgn(saw) and triangle is abs(saw). The triangle will be positive only so you need to subtract 5 volts and multiply it by 2.

The problem with this approach is that you get horrible aliasing. So you would need to oversample it heavily. Something currently not supported by SE.

Aren't there 3rd party oscillators with outputs for each waveform ?

probably, and i normally just use multiple osc if i need that, i just thought i'd try something different...

That sounds cool, I should try that.

You should really try to create some more complex formulas. I like the sound when you throw in a divide in the waveshaper. The best way is to experiment.
