Fractals:

lein repl
(use 'com.zimmermusic.fractals)
(fractals '(0 6 1 2 6 11 5 4))

Only argument is a sequence of integers between 0 and 11. First a vocabulary of 12 functions that produce sound are created, and then a section will be played for each provided integer n. During each section, n functions will be played for n seconds, starting at n pitch, at n tempo.

Each sequnce of integers will produce a new piece, but the piece will be exactly the same for each. The more integers provided, the longer the piece will be.

Windows:

lein repl
(use 'com.zimmermusic.windows)
(windows "/path/to/sample.aiff" [2 3 4] 10000 400)

The first argument is an audio file. It needs to be sampled at 44100 and stereo.

Second argument is a vector of scalars at which to create additional windows past the one created with:

Third argument: the base window size, in samples.

Fourth argument: the base step size, how far to move the window after each repetition

Spheres:

.. music plays ..
(end)
.. music fades away into oblivion ..

NOTE that you will not be able to run as is, as the piece references a series of samples that I cannot include due to licensing.

So to run, you need to create samples under overtone-compositions/resources: "m38.aiff" "m41.aiff" "m44.aiff" "m47.aiff" "f50.aiff" "f53.aiff" "f56.aiff" "f59.aiff" "f62.aiff" "f65.aiff" "f68.aiff" "f71.aiff" "f74.aiff" "f77.aiff" "f80.aiff" "f83.aiff"

These should all be around 60 seconds of an instrument playing the midi note represented in the file name.

I can help you figure out how to get these do this if you are interested. Maybe I can find some on freesound but I haven't been able to yet.

Diamonds:

lein repl
(use 'com.zimmermusic.diamonds)
(diamonds 10 14000)  ; 10 = maximum number of voices to build to, 14000 = duration of each section
... piece is bootstrapped and a screen pops up
press return in the new console screen
