New Wave Draw example

You guys just rock so unbelieveably hard 🙂

FragileX · 23 Mar 2006

Woooow !!

w00t! 😀

great work chaps, keep it rolling..

To SM team: I'm curious, how the bandlimiting in the Wave Table Read module is implemented. Are you FFT'ing the wavetable, or do you use BLIT techniques?

stefan · 24 Mar 2006

FFT, I don't see how BLIT could be applied to do this. If you know something I don't know, do tell 😉

I've started fiddling out with generating arbitrary mathematical waveforms (instead of drawn) using these new components, so far, it has worked well.

Tom7777 · 24 Mar 2006

Thanks for the example 🙂

Shifrin · 24 Mar 2006

Fantastic! I'd been doing something like this (wave drawing) a while ago using my own drawing schematic and feeding the graph data to the FFT module, then mapping the frequency/phase data to a bunch of 'fast sin' modules - needless to say my old (and buggy) work is now redundant! 😀

Ohhhh!! The "new wave" example, I thought you were going to have a Flock of Seagulls or Depeche Mode remix or something. 😉

platinumears · 24 Mar 2006

This is great!! 😀

I would be very interested to see examples of this.. 😉

"Morphing" waves works well:

Wave Morph

😍 😍

MyCo · 24 Mar 2006

That Morphing is realy nice. I haven't tested those wavetable modules, but I've a question from looking throught the schematics: Is the Wavetable limited to 256 sample points ?

Yeah, it's a fixed size for now. It actually started as a flexible component accepting any size. The flexible versions of the components will probably be released at some stage but they require extra testing first. The wave table component creates 256 waves of 256 samples each. Looking at the FFTs, it produces good quality bandlimited waves and it's quick to calculate allowing for responsive drawing while playing.

If you have requirements for different size waves please let us know which size and why you need it.

nice one PE 😇

platinumears · 24 Mar 2006

I had a go at the math waves thing:

Math Morph (drag around on the display!)

I still want to see what stefan did though.. 😉

Tom7777 · 26 Mar 2006

platinumears great examples, just wondering how did you make the array shapes in the Math Morph example? is there a document somewhere which has 0-1 value listings ect or did you draw them by hand somehow?

aiit · 26 Mar 2006

Thats F*$#% cool.

sambean · 26 Mar 2006

Nice one 'Ears, smooth control and sounds great.. 😀

I calculated them in SM using floats and a timer:

Then deleted all but the array modules. 😉

Tom7777 · 26 Mar 2006

Thanks 🙂

sonicfire · 28 Mar 2006

Why do these start to calculate when you press "off"? 🙂

You might want to try out the "Int Loop" component, it is a R&D component though.

Aha! Thankyou. that will make life easier! 😀

Because I hadn't discovered the "loop" modules yet.. 😉

That's a neat idea! I'm wondering if one could have done the arrays in Xcel, then cut & paste a table into a Text....

here's an LFO driven morphing wavetable thing based on what has gone before. DOWNLOAD

This one features 8 waves, the 4 from platinumears example and 4 'samples' extracted at random from my oscillators sample folder 🙂 just stuff with interesting harmonic content.

The lfo which scans across the 8 waves, quite a useful device, like one of these - http://www.doepfer.de/a144.htm

BTW - I'm still having problems accessing the properties, even more so with this OSM. try clicking on the 'num of steps' property on the '8-way morph' module. I can't edit that on the properties panel, yet it should be selectable /editable!

Nice! 🙂
