Yahoo Tuning Groups Ultimate Backup makemicromusic 'Equal Divisions Explorer' in CSound

Hello.

I just finished a Csound program to explore "equal divisions" scales with a MIDI keyboard:

<http://br.geocities.com/hfmlacerda/EDexplorer.csd.txt>

Users can have direct control on:

0) Number of divisions of the octave (or pseudo-octave);
1) (Pseudo-)Octave for timbre (stretched/shrunk octaves);
2) (Pseudo-)Octave for scale (to be divided in equal steps);
3) Fundamental frequency for MIDI pitch 69;
4) Amplitude factor for partials;
5) Nominal amplitude (volume) for the tones;
6) Number of partials (up to 11);
7) Option to quantize the partials into the scale.

This allows to explore several EDOs with/without *induced spectra*.

Thanks to Bill Sethares for the formalization of the relation scale/spectrum and for the concept of induced spectra.

Best wishes.
Hudson Lacerda

Probably you want to remove the ".txt" from the file name...

Not sure if Hudson has the same reason as me, but when I put CSD files on my site, I add the .txt extension as well, because it makes it easy for someone to look at the file in the browser by simply clicking the link. It's a simple matter to rename the file once you have downloaded it.

That is because GeoCities accepts only a few extensions in file names.

By the other hand, CSound doesn't recognize the .csd file with another extension. To run the program, you *must* change the file name extension to .csd.

Yes, Csound requires the .csd extension. To be clear, I use .csd.txt on my site not because of hosting issues, but because browsers know how to display a .txt file, but don't know how to display a .csd file.
