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 :-).
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:
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.
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

https://skr4ch.com/ lets you draw your own custom waveforms from scratch. its crazy.

Spent several hours back in the 90’s using Orangator to do this.

Seems to still work pretty good, just need to use ‘tab’ to select
the modulation options under the sliders:

@martblek has created several excellent waveform generator tools for renoise. I use Harmonio and Macuilxochitl ALL the time
Check his gumroad. Very reasonably priced and excellent functionality

Orangator - legendary software!
strange that nobody mentioned these:

Waveedit looks quick and powerful; downloaded, thanks for the link!
the single cycle waveform writer in paketti - if there’s simple lowhanging fruit improvements you’d like to have me look at adding, please describe them.
it currently allows for using AKWF directly from within Paketti
can do harmonics of a sinewave
can double up the octave
can import wavetable
can export wavetable
can export a wavetable instrument with LFO control over Wave A / Wave B modulation - automatable directly
can create a randomized Wave A & Wave B, or randomly pick from AKWF
can create unison instruments from Wave A & Wave B
can directly draw to Wave A & Wave B canvases and hear the result during “Live Pickup Mode”
control over frame length (64, 128, 256, 512, 1024 or so).. etc.
OK, cool, an interesting thread… I see Jek has already mentioned Orangator which was very good I liked the version 3 but it was much more involved & took university level classes to learn but could also use VSTs & hook-up to MIDI keyboard…
There was much of these 25 years ago as it was a primary way of rendering out instruments before VSTi came in… Some were very good like SMoRPHi 3.0 which quite rocked… ACiD WAV (later renamed Ace of WAV) was also good allowing layering & much more… Others were FX2, Quack, ADsynDX, Timbrewolf, Virtual Waves, Beam, Visual Orangator I’m sure I’m forgetting a few…
Though later there was apps like HourGlass & Cecilia that would have similar tools but much more going on… I like HourGlass (still use it) as you can process your sample by using a VST Effect plus automating any VST parameter via envelope thru the scrub… HourGlass is still on Softpedia I think, the last version 1.4.5…
so, after taking a look at the custom wave generator, i’ve added
arc cosine, arc sine, tangent, variator, time-based morpher, load sample as source, cycles control, and frequency multiplier.
to the paketti single cycle waveform writer.
