Yahoo Tuning Groups Ultimate Backup tuning '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

Can you facilitate this for people like myself unacquainted with CSound? A
step-by-step set of instructions would be most helpful.

Cordially,
Oz.

Instructions for... ?

0) Install CSound -- this is system specific. See:
<http://www.csounds.com/>
<http://www.csounds.com/manual/html/index.html>
<http://kevindumpscore.com/docs/csound-manual/>

1) Get the file with the `Equal Divisions Explorer' program.
<http://br.geocities.com/hfmlacerda/EDexplorer.csd.txt>

2) Rename the file *without* the extension ``.txt''. The file name
*must* end in ``.csd''. This is the unified ``Structured Data File Format''.

3) Attach a MIDI input device to your computer.

4) Revise the <CsOptions> according to your system (-+rtaudio=<?>, remove --sched for csound version < 5.00); I hope the code works for csound-4.22 or later.

5) Try running the command:
csound EDexplorer.csd

BTW, since just a few days my installation of CSound is not working anymore (shared object for FLTK widgets can't be loaded). :(

Hudson, there seems to be a problem with the --sched trigger in the text
file when running csound EDexplorer.csd.

How do I change the midi device in csound?

Cordially,
Oz.

Hi Ozan.

You need Csound-5.0 or newer for GNU/Linux to use --sched (real time priority). You can remove this option for other versions. Here I use Csound-5.01.1 on Debian GNU/Linux. --sched only works running csound as root, then one have to run ``sudo csound ...' or `su -c "csound ...".

The midi device is set by the -M option.
<http://csounds.com/manual/html/CommandFlags.html>

You can also choose the midi channel by assigning a channel to an instrument with massign:
http://csounds.com/manual/html/massign.html

Cheers,
Hudson

I downloaded CSound 5.01 for Windows 98/ME, I think. I still wish to hear
something with it, but all my efforts were for nought. The DOS command
interface is too bulky for a windows user like myself! Do you have a Cecilia
version instead?

Cordially,
Oz.

I would suggest you to install the version 4.23 or 4.24. Version 5 is yet in experimental stage and it may not work in some systems.

Csound expects the executables are available in a directory in the %PATH (and some few system variables more). I don't know how to do this on non-95 or non-98 versions of Windows. For Win95 and Win98, I recall that the variables are set by editing `C:\autoexec.bat'. Have `doskey' running is also helpful.
See:
http://www.csounds.com/manual/html/ch06s02.html

About GUIs, there is a CSound for Windows compilation called Winsound:
http://www.csounds.com/installing/howtowindows/index.html

See also this version with a fancy GUI interface (CsoundAV):

> Do you have a Cecilia version instead?

No. DeMuDi includes Cecilia but I removed it because I never used it. BTW, Cecilia is a program to help creating CSound code, not a CSound version. Nonetheless, maybe you can find Cecilia useful as an interface to run CSound.
http://cecilia.sourceforge.net/

Cheers,
Hudson
