cool, but where can I dl the tools? 
My bad
Very interesting! I was thinking a while back of a similar project for automation curves 
Using mashup on an unsliced sample gives:
Also, could you leave the tools window open after pressing ‘go for it’?
** Please download again from the new links, updates
Ah yes, it should warn you first.
Well I could but it would also need other updates to make any sense, namely, the instrument where mashup gets the slices from is not saved into the new atm… But it’s a good idea.
I’m getting the same error:
[b][i]'C:\Users\plugexpert\AppData\Roaming\Renoise\V2.8.1\Scripts\Tools\nl.jeweett.MashUp.xrnx' failed to execute in one of its menu entry functions.
Please contact the author (Cas Marrav | Casper) for assistance…
std::logic_error: ‘invalid sample index ‘-2147483648’. valid values are (1 to 1).’
stack traceback:

main.lua:147: in function ‘render_mashup’

What do you think is best, just a error msg saying “slice it first” ? ;D
OK so I could extend the beast with an extra option if there are no slices just autochop it in say 64 equal pieces (or with 64 value customizable)… but I don’t really want to today. Maybe tomorrow.
don’t know if I should be asking this but, what do you mean?
Where you can enter formulas for generating automation curves of different shapes, similar to how you have for generating waveforms (or have a completely misunderstood what this tool does?) {Possibly combined with the little automation tool I did that alternated between exponential curves of opposite polarity, so each x time division (eg 1 line) you could alternate from two different equations for the curve.}
Hey Cas,
I love overtune and use it a lot. I struggle a lot with building anything from scratch so I use it by loading presets and then tweaking the numbers and formulas. The discovery process is fairly random but I do manage to get some fantastic sounds out of it.
A preset system for future versions would be great.
Also some kind of beginners tutorial would really help if you intend this for educational purposes.
Cheers
Hey fathand,
great to hear that! Have you read the page for overtune on my wordpress already? Even though it’s based on V1 everything should still also work… Anyway it’s here. I like to think once you get used to the shitty things about Overtune (mainly having to click in the input field two times) it’s pretty usable. In the near future I’ll surely have something in mind for a step-by-step tutorial thing like the drum synthesis tutorial that’s also on my site. But I think first Overtune has a few small update things to get, presets might be one of them, at least a user customizable ‘init’ preset…
I’ll think about what to put in the beginner’s guide 
thanks for your comment.
Later
Overtune v2.2 is now live on the tools page with more updates since the last posted here…
changes:
- fully keyboard operated
- 1 preset
- gui with logo
- minor bug fixes
Overtune is updated with some extra helper functions, they’re documented on my overtune page. New version is live on the tools page again.
coolest stuff in the updates:
- expsin/tri/saw now also works with ‘roots’ so you can do expsin(X, 1/4)
- ltan function that just limits a tan so you can use it for waveform making and modulating
- sqtsin/tri/saw functions added that work like return sqrt(sqrt(sqrt(…(sin(X))))
- 8 ramp up/down functions for easier building of ‘envelopes’
this file shows a lot of the functions and possibilities
regarding ‘mashup’, when no sample data is present, the tool throws up the following notice:
There’s a new update that allows to edit waveforms with the same functions that you have when building an Overtune. It takes (currently) the form of a different window, different shortcut, and does not save your edit-formula, but it’s already capable of doing cool stuff. The default formula loaded in is
crush(Y*sin(X*35), 10)
which works coolness (read: mad distortion) on e.g. a rendered drumloop. (Note that using the edit window can take a lot of time on big samples, but a 4/4 beat should render without you having to click “no, don’t stop the script, it’s taking time but it’s probably doing exactly what i want”)
The other thing is that there now are lowrnd(T, num) and lownoise(T, num) functions. lowrnd is like rnd (you’ll still want to bi() it unless you use it for modulation) but sample-and-holding a number of steps. So a fun formula is e.g.
bi(lowrnd(T, 25+bi(rnd(10))))*rd(T,1)
to enhance your kickdrum with a small noise thing. (I used times=8 on it)
lownoise() does the same thing but you can instead of frames, define how many changes should occur in the T time. You could use
lownoise(T,12)*sin(X)
to wickedly distort a sine tone.
I updated the top post too but quickest is to get it at my tools page. Let me know what you think about it!

Really must get around to studying these tools properly!
the mashup link isnt working. it directs to a 404 page not found page. i am interested in the whole equation thing so could you help?
