OuterSpace.

OuterSpace is an "instrument" for PD aimed to the generation of ambient sounds and textures.  The instrument is based on white noise filtered by a bank of 128 (!) band-pass filters spread across the audio spectrum. Each filter contributes to the overall sound as an independent "voice", in total 128 voices. Each voice has a "quartic" attack and decay amplitude envelope triggered independently. Each voice is then placed in the stereo field and rotated from left to right following a low frequency oscillator (LFO), plus some spread. The left and right output are then catched and summed up in mixing buses. The output is reverberated using freeverb~.  

Go to the download section: there you'll find the PD abstractions, an mp3 sample of OuterSPace presets, a screenshot of the GUI and some doc:

Enjoy OuterSpace and leave me a feedback !

PS - Win users: I made a tailored version of OuterSpace that instead of freeverb~ uses the good quality VST SIR reverb (http://www.knufinke.de/sir/index_en.html). T. Grill's VST~ external has to be used. Just send me an e-mail, I'll be glad to share it. In my opinion it sounds a bit better..

Mondrian

Mondrian is a noise generation and visualization machine for pd. Why is it called "Mondrian"? Take a look at the screenshot, you'll sure recognize something similar to a Mondrian painting. It is a small toy assembled in few hours using existing pd components like cyclone, creb and grid.
Since I think it is not completely bad or ugly, I'd like to share it. If you like it (or even if you don't) leave me a little feedback on my e-mail address reported in the docs. The following is the download section for the patch, docs and screenshot:

xYzee!

xYzee! is an automatic audio generation toy for PD. It is a two voices device, based on bassemu external. The following is the download section for the patch, docs, mp3 and screenshot:

Win32 port of LyonPotpourry externals

I did a port of Eric Lyon LyonPoutpourry externals for Win 32. They are here:

Colored Noise Generator

This abstraction implements an algorithm for the generation of "colored" noise (white, pink, brown...) by varying a continuous parameter that represents the slope of the spectral density in a log(PSD)-log(f) (linear) plot. May be useful for synthesis of noise with predominantly low frequency like rumbles, winds etc. Grab the zip package here:
