Thank you for downloading Borderlands!
//------------------------------------------------------------------------
// Release Notes:
//------------------------------------------------------------------------
Version 0.04
-Independent volume control for clouds in dB, controlled by b key (with number entry or shift modification as described in usage instructions)
-Full screen/windowed toggle mode - press o key
-Bug fix - selected grain duration was not being applied to newly added grains (due to missing break in a switch statementÉ)
Version 0.03
-Multichannel support - change MY_CHANNELS in theglobals.h to use > 2 channels, use T key to switch between spatialization modes
-Playback rate LFO frequency control - K key
-Playback rate LFO amount control - L key
Version 0.02
-Linux compatible version released.
-Extraneous files removed from the distribution.
-Some platforms may have problems displaying the grains - they may appear as squares
instead of circles. This is due to lack of support for GL_POINT_SMOOTH on the
user's graphics card. A version that uses gluDisc to render the grains is
available at the project site. It is lower quality, but it worksÉ Squares are nice too...
Version 0.01
-First version, produced for Music 256a at Stanford. OSX only.
//------------------------------------------------------------------------
// Installation:
//------------------------------------------------------------------------
Borderlands has only been tested on OSX 10.6.8.
Please make sure the following libraries are installed on your system.
Libsndfile is used for loading .aiff and .wav files
http://www.mega-nerd.com/libsndfile/
NOTE: When installing libsndfile, make sure you use the following command. The current documentation for libsndfile is not clear
in this regard.
./configure && make && sudo make install
"sudo" is necessary to give you root privileges for the install.
NOTE: On OSX, I would recommend using Homebrew (http://brew.sh/) to install libsndfile (rather than installing manually as described above). Homebrew makes the process much easier:
To install home-brew, paste this into Terminal and hit enter:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Once Homebrew is installed, type:
brew install libsndfile
If libsndfile installs correctly, continue installing Borderlands as described below. If the libsndfile install wonÕt run (or requires admin privileges, try
sudo brew install libsndfile
Once libsndfile has successfully installed, navigate to the Borderlands_v0X/Borderlands directory in Terminal, and type make.
Note - if you donÕt understand what is meant by Ònavigate to the Borderlands directory,Ó follow these steps (if you are on a Mac):
-Open Terminal
-Type cd and add a space
-Open the Borderlands_v04 directory in Finder
-Drag the Borderlands folder into the Terminal window next to cd (should now look like cd Users/you/blah/etc/Borderlands_v04/Borderlands).
-Hit enter to change directories.
-Now type make and press enter. Borderlands should start compiling.
If all goes well, the source should compile. You may see a number of warnings about glut functions being deprecated if you are on Mavericks. Please ignore these unless you get any errors that prevent compiling from completing. If you see errors, please email me at carlsonc AT ccrma DOT stanford DOT edu and I will try to help resolve any issues quickly!
//------------------------------------------------------------------------
// Before runningÉ
//------------------------------------------------------------------------
Put your favorite .wav and .aif files into the loops directory contained in the distribution.
These will be automatically loaded when you launch Borderlands.
//------------------------------------------------------------------------
// To launch the softwareÉ
//------------------------------------------------------------------------
Type ./Borderlands from the source directory in terminal. The screen will be black for
a bit while your audio files load, and then you will see a title screen with instructions.
//------------------------------------------------------------------------
// Controls
//------------------------------------------------------------------------
The user interaction is primarily mouse and keyboard based. Here are the main controls:
Entry/Exit
------------
ESC Quit
? key Hide/Show Title Screen
o key Toggle fullscreen/windowed modes
Rectangles
------------
Left click Select
Drag Move
TAB key Cycle selection of overlapping rectangles under mouse
R key + drag Resize
F key Flip orientation
Cloud Addition and Selection
------------
G key (+ shift) Add (remove) cloud to/from end of collection
Delete key Remove selected cloud
Left click Select
Drag Move
Cloud Parameters
------------
After selecting a cloud, parameters associated with the granular synthesis can be edited.
Most parameters involve keyboard interfacing. Select the key corresponding to the mode,
then press it again to change the value. In some cases, numeric keys are used to enter
specific values. In parameters associated with grain motion, the mouse is used.
V key (+ shift) Add (remove) voices
A key Toggle cloud on/off
D key (+ shift) Increment (decrement) duration
D key + numbers Enter duration value (ms) - press Enter to accept
S key (+ shift) Increment (decrement) overlap
S key + numbers Enter overlap value - press Enter to accept
Z key (+ shift) Increment (decrement) pitch
Z key + numbers Enter pitch value - press Enter to accept
W key Change window type (HANNING, TRIANGLE, EXPDEC, REXPDEC, SINC, RANDOM)
W key +
1 through 6 Jump to specific window type
F key Switch grain direction (FORWARD, BACKWARD, RANDOM)
R key Enable mouse control of XY extent of grain position randomness
X key Enable mouse control of X extent of grain position randomness
Y key Enable mouse control of Y extent of grain position randomness
T key Switch spatialization modes
L key (+ shift) Adjust playback rate LFO frequency
K key (+ shift) Adjust playback rate LFO amplitude
B key (+ shift) Adjust cloud volume in dB

Thanks to Ge Wang and Jorge Herrera for their guidance through the initial stages
of this project. Thanks to Mike Rotondo his help in my early brainstorming discussions.
Thanks to Tarik Barri for encouraging me to pursue the idea and for suggesting the
use of the second dimension of the sound rectangles!
