Subject description: cheap slew circuit with individual up/down rate controls -2 versions, optimised for control or audio
Reply with quote  Mark this post and the followings unread

Here's another cheap building block -a glide circuit with individual rate control for rising and falling.

Since it is based on feedback, the slopes are not linear.

Two versions, optimised for control and audio rates respectively.

The audio rate one is quite interesting for waveshaping applications. It's like having a filter which can treat rising and falling waveform flanks independently. Can be used to morph square waves into sawtooths, or sawtooths into triangles. Produces interesting harmonics on filter resonance peaks too, as it warps the sinusoids. Gotta explore this... Smile

0,5 cycles/3,9 memory for the control rate version; 2,2 cylces for the one running at audio rate.

have fun Smile

That's a nice one, cheap !

The audio rate version can do some nice tone control like things.

Hi,

Any chance to get the circuits in JPG, PNG or PDF?
I can't open those files...

thank you

With the G2 demo software you can not only see the patches but hear them too.

You can download from http://www.clavia.se/products/nord%20modular%20G2/default.asp .

If that doesn't work for you please say so, I'll make some screen dumps then.

Thanks. I'm confused now... is this a software patch or an electronic circuit?

(excuse my ignorance!)

These are patches for the Clavia Nord Modular G2 which is a simulation of an analog modular synth on hardware box having a couple of DSPs. The Demo software I referred to is a demonstration of the actual hardware product. As such the patches are software really. Still the G2 demo can be an interesting prototyping tool to quickly test out hardware ideas without building anything in hardware.

I'll attach a screen dump of the first patch, it's probably not what you're looking for ?

very interesting, thank you.

I have experience with analog, tape splicing (computer edit now =:) and then csound or Max/MSP, but this looks good!

I'll investigate further, thanks again
