'Csoundo' is a Csound library for Processing. Copyright (c) 2010 Jacob Joaquin firstname.lastname@example.org http://csoundblog.com/ Update to Processing 2.0, and addition of Android support by Conor Robotham, 2012. Note ---- Csoundo development is in early Alpha. Though people have been successful in running Csoundo on Linux, OS X and Windows, there are still many issues that are preventing people from getting Csoundo to work on their computers. For example, Csoundo only works with the floats version of Csoundo, not doubles. (see "Known Issues" at the end) What is Processing? ------------------- "Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production." http://processing.org/ What is Csound? --------------- "Csound is a sound and music synthesis system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in the creation of classical, pop, techno, ambient, experimental, and (of course) computer music, as well as music for film and television." http://csound.sourceforge.net/ Running on OS X --------------- 1) Install Csound. Only one version of the pre-built Csound binaries has been confirmed to work on OS X, and only confirmed to work on Intel machines: csound5.12.4-OSX10.5-Universal.dmg http://sourceforge.net/projects/csound/files/csound5/csound5.12/csound5.12.4-OSX10.5-Universal.dmg/download 2) Copy the Csoundo folder into your Processing 'libraries' folder. See instructions at Processing.org: http://wiki.processing.org/w/How_to_Install_a_Contributed_Library 3) Copy or make a symlink to the csnd.jar file. The csnd.jar is located here: /Library/Frameworks/CsoundLib.framework/Resources/Java/csnd.jar Make a copy of csnd.jar in this folder: yoursketchbook/libraries/csoundo/library Alternatively, you can create a symbolic link using the terminal app. $ cd yoursketchbook/libraries/csoundo/library $ ln -s /Library/Frameworks/CsoundLib.framework/Resources/Java/csnd.jar csnd.jar Running on Linux ---------------- I do not have linux installed. If you have better instructions, please email me, and I will incorporate them into the Csoundo knowledge base. 1) Install Csound: http://csound.sourceforge.net/ 2) Copy the Csoundo folder into your Processing 'libraries' folder. See instructions at Processing.org: http://wiki.processing.org/w/How_to_Install_a_Contributed_Library 3) Copy or make a symlink to the csnd.jar here: yoursketchbook/libraries/csoundo/library To create a symbolic link: $ cd yoursketchbook/libraries/csoundo/library $ ln -s /Library/Frameworks/CsoundLib.framework/Resources/Java/csnd.jar csnd.jar 4) Make modifications to the 'processing' lauch script. There is currently one known method for running Csoundo on linux. That is, to make to modifications to the 'processing' launcher script in the root folder of Processing. A. Towards the very end, right before the line "# Start Processing in the same directory as this script", add this code (your csound plugins folder may vary): #make sure that OPCODEDIR is set.. export OPCODEDIR=/usr/local/lib/csound/plugins log OPCODEDIR B. Replace the last line "java processing.app.Base "$SKETCH" &" to the following: java -Djava.library.path=/usr/local/lib processing.app.Base "$SKETCH" & Thanks to Rory Walsh for this info. Running on Windows ------------------ There have been reports of Csoundo working on various versions of Windows. I do not have Windows installed. If you have better instructions, please email me, and I will incorporate them into the Csoundo knowledge base. 1) Install Csound: http://csound.sourceforge.net/ 2) Copy the Csoundo folder into your Processing 'libraries' folder. See instructions at Processing.org: http://wiki.processing.org/w/How_to_Install_a_Contributed_Library 3) Copy the csnd.jar here: yoursketchbook/libraries/csoundo/library ------------------------------------------ Csoundo Android ------------------------------------------ Quick setup for advanced users: 1.Add csoundo and CsoundAndroid folder to the processing libraries folder. 2.Open the CsoundAndroid folder and change the sdk.dir path in the local.properties file. 3.Backup and replace the Processing pde.jar with the provided pde.jar.(Processing/lib/pde.jar) CONTENTS: A. PROCESSING ANDROID. B. CSOUNDO ANDROID. C. OVERVIEW OF A CSOUNDO SKETCH FOLDER D. CODE REQUIREMENTS E. EXTRA NOTES: Detailed steps for setting up: A. PROCESSING ANDROID.(Referenced from wikipidea entry) 1. Download Android SDK: http://developer.android.com/sdk/index.html 2. Run the SDK Manager and download the following items: Tools/Android SDK Tools(Already Installed) Tools/Android SDK Platform-tools Android 2.3.3(API 10)/SDK Platform Android 2.3.3(API 10)/Google APIs Extras/Googe USB Driver 3.Download Processing 2.0b6. (Csoundo tested, previous 2.0 beta versions may be compatible. Tested 2.0b3) 4.If required, download the latest USB drivers for your android phone.(See manufacturer website) 5.Run Processing and click on the box in the top right hand corner labeled JAVA. Change to ANDROID. A window will appear requiring you to navigate to and select your Android SDK. 6.Connect your android phone via USB cable. Go to file>Examples.. and try an android example. Click the play icon or hit Ctrl+R. B. CSOUNDO ANDROID 1.Place csoundo folder in your Processing libraries folder. Thats: \Documents\Processing\libraries 2.Open the main processing folder(the program) and go to the lib folder. Backup the pde.jar file to another location and place the provided pde.jar into the lib folder, overwriting the original. (AndroidBuild file provided for reference is the source code of the modified class within the pde.jar) 3.1 Install CSOUND Version 5.18, or see EXTRA NOTES if you already have a CSOUND Version. 3.2 Copy the built CsoundAndroid folder provided into this folder. 3.3 Open the local.properties file(With TEXTPAD or another editor) within the CsoundAndoid folder and change sdk.dir path for the android-sdk on your computer. 4.Open the csoundo examples folder from processing and test a sketch. You must comment/uncomment the csoundo instantiation to switch between Java and Android mode. C. OVERVIEW OF A CSOUNDO SKETCH FOLDER *The only required files for a developer are the main .pde file inside the main sketch folder, and the .csd file of the same name, in the data folder. 1.Inside your sketch folder, is the main .pde file of the same name, along with any other .pde or java files used in the project. 2.The csound .csd file is located in the data folder, and must be named exactly as the project name(caps-sensitive) 3.icon-36, icon-48 and icon-72 are optional, and the default Processing icon will be used if they are left out.(Csoundo icons are provided) 4.A sketch.properties file is created automatically inside the sketch folder, used by Processing. 5.A __CSOUNDO__.csd file will be created and overwritten inside the data folder for every Java Build. Editing this file will have no effect. 6.An AndroidManifest file will be automatically created by Processing in the sketchfolder upon Android run. D. CODE REQUIREMENTS Csd file 1.1Within the .csd file the following options must be specified.(Modify bravely) <CsOptions> -o dac -+rtaudio=null -d -+msg_color=0 -m0 -b512 </CsOptions> 1.2 The above are the Android Mode Options, Use cs.setOptions within your .pde code to set Java Mode csound options.(Otherwise working default options will be applied) 2.Use the chnget inside a csoundo instrument to specify a reference channel for Processing. e.g. kfreq chnget "pitch" Pde file 3. import csoundo.*; must be included at the top of your main .pde sketch file. 4. Csoundo cs; Csoundo object must be declared outside any methods.(Usually before setup()) 5. The cs object must be instantiated in the setup method using the Android Constructor: cs = new Csoundo(this, super.getApplicationContext()); or the Java Constructor: cs = new Csoundo(this, "MySketch.csd"); 6. cs.run(); Method must be called in setup method. 7. Csoundo methods can then be called in the setup or draw methods. e.g cs.setChn("pitch", pitchVar); inside the draw method. E. EXTRA NOTES: - If you are not running CSOUND Version 5.18 it is recommended that you replace the csnd.jar file within Csoundo with the csnd.jar file from within your version of Csound. (Processing\libaries\Csoundo\library\csnd.jar) - modified pde.jar has only been tested with 2.6 beta and 2.3 beta, and likely will need to be updated for future versions. -It is recommended to debug in Java first and, if possible, add Android specific methods last. - for future versions of CsooundAndroid you can place it in the directory specified above, but, unless they have changed the way they release it, you will need to build it from the command line console to create the build.xml file required. cd to android-sdk/tools and run command: android update lib-project --target 1 --path C:\Users \Conor\Desktop\csound-android-5.18.03\CsoundAndroid Change path accordingly.
