I don't know if i can tell you anything that will get these specific shapes, but I have some general guidelines.
You can do a lot of subtle shaping tricks with just a shaper and crossfader. For example:
Say you want to flatten or round off the top of a saw wave but not the bottom (lots of analog synths have a saw wave with this kind of asymetrical shape). Connect the saw to one input of a crossfader. Also connect it to a shaper module set to INVx3 and connect the shaper output to the second crossfader input. Now here's the trick - also connect the saw to the CONTROL input of the crossfader and set both crossfader controls to 12 o'clock. Now, when the saw goes positive, the crossfader output passes the shaped saw, and when the wave goes negative, it passes the unprocessed saw. So the final wave is only 'shaped' on the top half.
You can use this idea for lots of variations to make waveforms that are shaped differently on the top & bottom. Try using two different shapers on the two inputs. Try overdrive modules or wavewrappers. Try a triangle wave instead of a saw. Try using a saw wave on one input and a sync'd pulse wave on the second input. Etc.
Another way to get asymetrical shaping is to pass the wave through a level shifter to make it positive only, then through a shaper, and then another level shifter to make it bipolar again.
Another way to shape raw waveforms is by using a filter that tracks the waveform frequency. Try using a highpass filter set to a relatively low fc with a good bit of resonance. Normally, we think of HPFs as something you use to make a signal sound thin, but when you set it to a low fc and crank the resonance, it will emphasize the fundamental or one of the low harmonics, which can make the waveform sound more big & bassy.
Enjoy! _________________ Dave Peck |

That’s looking good, the funny spike I think is a Sinc pulse and is part of Clavia’s anti-aliasing, they pop up sometimes when doing wave shaping.
I had a think about this question while waiting in the supermarket car park. Here is the result. Using a compare to get a rectangle from the sawtooth and then using the sawtooth to AM the square or a saturated sawtooth.
What soft scope are you using BTW?

Hey G2Ian,
Ah nice technique... and I'm stunned as to how close the pulse wave sounds to the real thing in a side by side comparison!.. and the saw will only take a little tweaking to get it spot on I think.
Great stuff (hope you didn't forget any shopping due to contemplating this )
I'm using a softscope in OSX called Wavewindow

Elise (3) fell asleep on the way so I got to sit in the car with her while her mum and three brothers did the shopping

Hey Dave,
Your discussion of Shaping tricks made me try out something in a patch which I was going to post (a digiridoo-ish thing), but I have once again screwed up and you can't open it in the editor ...
But time will heal this I hope ... unless the file format changes again ...

Dave,
Thanks for the kind words ...
Quote: | BTW, how can you screw up a patch so that it won't open in the Editor?? That sounds really annoying and I'd like to know how to avoid that. |
Uhm, the patches do not open in v1.32 ... but they do open on one of my G2's ...
I like the modded patch ... I should do more variations ...

Avoid beta testing then :-) _________________ Jan

Yep, that's how I use it. It might be too simple for some peoples tastes, but great for just scoping waves, check out the demo. |

Maybe http://www.sonicspot.com/wavetools/wavetools.html ?
It says it needs windows 3.1, but once I had it running under XP, although that was before installing SP2 I think. _________________ Jan

I use the first one (VA.EXE) but not the latest version which looks better but mysteriously won't run on my XP machine. |

yeah, VA's latest version gives me all kinds of trouble, lately... maybe due to XP updates? i'm not sure... it worked fine once upon a time...

This one isn't stand-alone, but it will run in ASIO if your host is set up for it:
s(M)exoscope
