Freiscale Semicomposer

A (very rough prototype of a) composition program with extensive visualization and no scales.

Suggested Sample Library

If you launch freiscale with the command-line parameter lib:path/ it will look in path/ (relative to the current working directory) for samples. If you don't specify the command-line parameter, it will look in the directory sounds/ (relative to the executable) for a sample library.

A sample library is just a bunch of wav files in folders. You might want to give them descriptive names.

The OLPC project has links to samples here: http://wiki.laptop.org/go/Free_sound_samples

Particularly, I have used the "Open Path Music Collection" packages in much of my testing.

Build Instructions

#Prerequisites:
$ sudo apt install ftjam libglm-dev libsdl2-dev libpng-dev

#Checkout code + submodules:
$ git clone git@github.com:ixchow/freiscale
$ cd freiscale
frescale$ git submodule update --init

#Tune otfft (optional):
freiscale$ cd otfft-11.5e/otfft
freiscale/otfft-11.5e/otfft$ make ffttune
freiscale/otfft-11.5e/otfft$ ./ffttune
freiscale/otfft-11.5e/otfft$ cd ../..

#Build otfft (not optional):
freiscale$ cd otfft-11.5e/otfft
freiscale/otfft-11.5e/otfft$ make otfft.o
freiscale/otfft-11.5e/otfft$ cd ../..

#Build:
freiscale$ jam

You can also build against the ixchow/kit-libs-linux, ixchow/kit-libs-osx, or ixchow/kit-libs-win packages instead of installing glm, sdl2, and libpng system-wide. This is especially useful on windows. Just check out the corresponding repository as a subdirectory of freiscale.

NOTE: If you are getting weird segfaults in the FFT code, there might be a compile flags mis-match between the flags used for otfft.o and the flags used by the code that interfaces with otfft.o .
