Tools for drawing single cycle waves

[slippycurb]

and zooming in on renoise’s sample is very handy, can get some quite detailed drawing done.

I use Curve2cm, best tool for painting waves (that sounds better than almost all of raw wavs) and making further modulation. Then render it and create xrni instrument

If renoise will get simple wave generator, better modulation of parameters, i wont need it :-).

Ive put together a Puredata patch for drawing single cycle waveforms…it calculates how many samples per cycle you need and changes the internal size of the array that is used for drawing…you select sample rate (96000 or 44100) , note and octave. You can then save it too a 16bit 44100 wav file for importing into renoise. Instructions are within the patch…Dont know if you use PD or not, even if not, using this patch is simple.

Edit: Ive just updated the patch so you can use it just as a calculator if you want to do your drawing in renoise.

I have no idea how to use puredata, but i really need to find out how many samples i should use for different tones. Can you perhaps tell me the formula how to calculate this at 44100Hz sample rate and bit depth 16?
I use this page for reference and it shows both hertz value and wavelenght in cm: Frequencies of Musical Notes, A4 = 440 Hz
I imagine the cm value would be perfect to calculate this, but i’m not shure how it relates. How many mm is one sample?

Edit: Doh, stupid me! You already posted the formula here:

@slippycurb

ive wondered about this before, by looking at akwf’s page he set his cycles to 600 samples as that is 44100/fD2===44100/73.4162=~600…therefore if you want a single cycle @ C4…44100/261.626=~168.6

Thanks! Didn’t think it was that easy.

Hmm let’s see, how do i convert this into cm? Oh, well, doesn’t really need that.

Back to my project that now has escalated to the idea of drawing 480 different single cycle samples in one instrument. Damn, what a bad idea.

Audio-Term is a free program that some single cycle users might be interested in. Is kind of intended to be used to generate wavetables, but each cycle can be saved individually. So, you can easily make an evolving set of single cycles to use in your renoise or any .wav reading instruments.

Anyway, it has additive waveform building and some obscure (to me)transformation functions, blurring, filters, stuff and a wavedrawer.

Called term for a reason and looks and acts like some old, ancient 80s program all green monochrome and fairlight evocative. But is not old, latest update had files from Dec. 2013 in it. Only hard to use in the sense that it ignores any modern user interface conventions.

That looks great!

You got a latest link? Google doesn’t give me good results, not an official site for it afaik?

Hmm, yeah. He hangs around KVR a lot and usually puts up links in his sig now. Check this thread at KVR and look for a guy named blacktomcat. Maybe it’s not exactly what some people are looking for, but I think it might work well as an axillary tool for some.

Thanks, dl’d it from his sig.

@TheBellows

I wonder if anyone knows of an editor with easy to use tools that enables you to draw high precision single cycle waveforms?
Scipting/coding is not what i’m looking for as i don’t have time or patience for learning that stuff.

Some graphical vector freeware would be the shit! />

Id recommend taking a look at audiosculpt. It’s not for the faint of heart and the licensing scheme is a bit pricey but if you know what you’re doing it’s incredibly powerful. I use it to create waveforms for my wavetable hardware synths.
If you just want to draw freeform waveforms and don’t want to pay for anything just use Audacity.

wOOOww double wow
Audioterm is amazing

It’s partially based on the ppg wavetable …
But the main reason was for creating wavetables for terratec komplexer , and now also vember audio surge , and blofeld
