Looks interesting, but why not just run a step sequencer at audio rates? Maybe you don't want any pots in the circuit. _________________ --Howard

Looking and what you are trying to actrually build here, going stepseq seems like a smart idea. You could integrate both schemes? _________________ A Charity Pantomime in aid of Paranoid Schizophrenics descended into chaos yesterday when someone shouted, "He's behind you!"

I was trying to figure out why you wouldn't just use a step sequencer until I noticed the last post there pointing out:

Ah! Looks to me like something you should try out! This could be used to modulate VCO's at audio and subaudio rates as well, which would be very interesting, I think.
Keep those ideas coming.
Cheers,
Scott |

Yeah, that last bit was actually the main point. I was just making sure I didn't skip the foundations. Imagine Mosc having a little gnome hanging off each pot, re-adjusting it automatically, maybe from one value to the next each wave out, and back again, or randomly, or a combination of both.
The thing I really like is the potential to produce any wave shape at all.
Maybe it could be useful as a completely separate type of VCO. If not then it should still be on par with another type of WSG, which would be cool too. In fact hanging something like the WSG filter section off the end could be all it needs to smooth out the aliasing as much as you like.
I need to finish soldering up the Roboride sequencer/driver board so that I can get some real-estate back on my breadboard, then I'm gonna get this thing squeaking ASAP.
Keep throwing back any ideas which come up about the actual implementation of it.
It's really great being able to bounce ideas off you guys before I even get the chips out! _________________ What makes a space ours, is what we put there, and what we do there. |

Hey Jan,
I love the look of that screen dump. It's gonna take me a while to work out what's going on (and whether that's what I mean) though.
I'll have another coffee (or 4) and get back to it! _________________ What makes a space ours, is what we put there, and what we do there. |

See it in the demo, with the lights flashing :D
I made a little mp3 of it, should I post it ? _________________ Jan

Cool!
Pretty unmusical, but also very f@!?%d up!
Just the kind of thing I love!
I imagine that actually putting it together using discrete components would tend to calm it down a bit, yeah? Maybe that would be a good thing. Maybe not.
What are the chances you could do another run, leaving the fundamental frequency constant (~440Hz?) and just slowly modding the waveform oscillators?
Thanks heaps for your help Jan _________________ What makes a space ours, is what we put there, and what we do there. |

Uncle K, why don't you download the free G2 demo from the Clavia site and try it yourself. It's a great too to prototype circuit ideas, like Jan said. _________________ --Howard

I've already got it Mosc. In a situation like this I'd prefer to keep the iron hot and leave the theory to the experts. I will give it a go soon though, just need to make some space on my breadboard! _________________ What makes a space ours, is what we put there, and what we do there. |

BTW,
Love the sample Jan.
If I use all four switches in a 4066, I'd be able to get 15 voltage levels out.
I've got four 8 way DIP switches, man this is gonna be one nasty looking breadboard! _________________ What makes a space ours, is what we put there, and what we do there. |

Jan- sorry- I tried to make your image slightly smaller- cos it wasn't fitting quite right on the page- but I think I've fucked up a bit- sorry
If you want to increase the size again- don't let me stop you

The thing is NM editor screen shots can't really be made any smaller, should do those in click me to explode me mode. _________________ Jan

How do you do "click me to explode me mode".
I was thinking the only way of posting anything with any detail in it would be to zip it. _________________ What makes a space ours, is what we put there, and what we do there. |

By putting the image on a webserver somewhere and using a link to the image in the message (using [img] tags) instead of an attachment. Such images will be auto-sized by the board's software. The thing is you can't delete the image later on, or move it. |

Judging by those samples, it sure sound like something worth pursuing, Uncle K.
I'll have to check out the NM demo program.....
