User waveforms

[FEV]

Thanks Bart! Er... I don't want to read the entire Python documentation for this - what's the precise syntax in the command line if I e.g. put your script and "test.wav" in Python's root directory, and want it to build "test.h2p"? I'm always getting the "invalid syntax" message.

Well, if you used an installer application to install python on windows, then .py files are already associated with python interpreter, so running a script is just a matter of typing it's name in the command line.
You have to provide two parameters - the first one is the name of the input wave file, and the second is the name of the output preset.
To make it a bit clearer on how to use this program, I'll give you an example:

wavToZ2.py and example.wav are in C:\convert directory. To convert example.wav, you must (in command line) type:

Code: Select all

C:
cd \convert
wavToZ2.py example.wav example.h2p

It would be even easier if you would add the location of wavToZ2.py script to the Windows PATH environment variable (then you would 'cd' directly into samples directory and call wavToZ2.py without actually copying it to that location).

Anyway if there's a demand for it, I can make a simple GUI for this script

cheers,
Bart

As I'm a little bored at work right now , so I produced a tiny python script, that should convert 16-bit mono wave files into Z2 osc presets.

This is wicked, will try it out asap. Another reason Mac's are cool - they come with perl, php and python preinstalled...

Thanks!

It works here on a PPC Mac...

Hmmm...I get an error even if I just type "c:" or "cd \"!! Does Python work with German keyboards?

Edit: OK! I just tried using the DOS Commander instead of Pathon's, and it works. Her's the Little Phatty Sawtooth (sorry about using up so much space - won't happen again!)

You should be typing those into the Windows command prompt, Howard. Start -> Run -> command to open a terminal.

Now CD to the directory, and run the python proggie from there...

Edit: ok, you've figured it out!

Can I assume from the smiley that I don't have to answer that question?

Huge demand here! Even as it is, it's a great little tool. But a simple GUI would also be quite helpful. Maybe that could eventually turn into *the* user-friendly tool for making Z2 waves... remember Cool Edit?

Many thanks

Well, I'm not sure you can call that a GUI, but I did a tiny adjustment to the script. Now when there are no parameters passed (you can just run the damn thing, simply by double clicking on the script icon), open file dialog should appear, where you can select file(s) to convert. The presets are saved in the same directory as sound files, with the same name as sound files + .h2p extension

The script is here

Little feature request - maybe the choice of creating a Geomorph oscillator rather than a Geoblend, with the waveform points basically tracing the outlines.

Anyone have any tips for getting a nice source waveform with a 128 sample cycle period? I'm kinda doing it a bit hit and miss - aer there any particular frequencies or keys that would give a nice 128-sample waveform cycle period?

Sorry, hehe, the spline based Morph curves are not (yet) accessible from within the scripting engine... Gotta work something out here that actually makes sense...
