This csd file will generate two wave files: one with a continuously and logarithmicly changing pitch from 20 Hz to 20,000 Hz, and then it will create a file using very basic code that generates a low pass filter treated version with cut-off frequency at 110 Hz. The header of the file shows how this code is derived from a simple RC-circuit.

This song may a bit long - but's it worth it. Listen to what csound can do.

This is my entry for the Summer 2011 CSound Catalog Competition. My time was about evenly split between creating instruments (choosing sounds, rendering them from QuteCSound, trimming silence or normalizing (if necessary), and creating Reason instruments.) The other half was actual composition/sequencing. I used Reason 5, as I am extremely familiar with the sampler instrument parameters and I didn't want to use my time figuring out how to accomplish the same tasks with Kontakt (even if Kontakt is more versatile).

This is my 6h catalog composition.
All the instruments come from the catalog.
I edited the orchestra to shape the instruments the way I wanted (and trigger some of them via MIDI, others are sequenced in the Csound score section and then rendered from there).
Everything is edited/sliced in Logic. Some sounds (perhaps the bass only) are mapped in Kontakt. Drum kit is mapped in Battery.
No effects applied (besides a reverb from Csound).
I wish I'd have more time to make some modulations and fill the middle section with something, but I spent too much time creating the instruments.

Here is my one minute csound note list piece that I did for Dr. B's csound class.

Had to make a 6 hour composition with the csound catalog for Dr. B's csound class. Spent most of my time making instruments and by then I only had two hours left to make a composition. Definitely seems unfinished. Anyway, enjoy.

"Mystical" is a one-minute notelist composition. It exclusively uses csound instruments, including several incorporating the loscil opcode that draws from audio samples of music instrument sound designs created by csound developers who contributed to the Csound Catalog (by Mikelson and by Varga). Attached are the .mp3 file for "Mystical" as well as a commented .csd file (for informational purposes only, as the audio sample .aif files are not included). Also attached is a readme text file that includes additional background material about the piece. Enjoy!
