A musical audio synthesizer written in Pd and HTML+JavaScript. This is an exploration of preset morphing (smooth interpolation) using dimensionality reduction with audio descriptors as a means of simplifying user interfaces for setting timbres.

Some wrappers and scripts are provided for compiling as a Linux Jack client (currently broken), an iPad application (currently incomplete) and running the synthesizer using a web browser as the GUI and pd-extended as the sound engine.

Tested in pd-extended 0.43.4

There is a simple GUI implemented in PureData. Just open the pd/patches/00_Morphasynth_GUI.pd patch and start playing. We'll probably deprecate this at some point in favour of the HTML GUI.

Tested using Google Chrome 26, pd-extended 0.43.4, Ubuntu Linux 12.04, Windows XP, MacOS 10.7.5, node 0.10.5

1. Install the dependencies as described below (you only need to do this once).
2. Start the scripts/development.sh script.
3. Open html/index.html in a web browser.
4. Open pd/patches/00_Morphasynth_NO_GUI.pd in pd-extended.
5. Start hacking.

The most practical way to hack or modify the code is to run and debug the HTML+JavaScript code using a web browser, open the Pd patches using pd-extended and use the provided script to allow for communication between both. You'll need to install some stuff first:

In Pd parlance, an external is a plug-in or an extension to the Pd language. They are usually built by people outside the core Pd team. We have included some 3rd party externals and built a few ourselves for this project and you'll need to either use the pre-compiled versions included in this repository or compile them yourself.

If you want to use the pre-compiled versions (recommended), all you need to do is open pd-extended, go to Edit -> Preferences and add pd/externals/bin, pd/externals/bin/tID and pd/externals/bin/directory to Pd's search path.

If you want to modify the externals, take a look at the different readme files in the subdirectories of pd/externals/src.

To allow communication between the JavaScript GUI code running in a web browser and the Pd sound engine running in pd-extended. You need to run the development.sh (Linux and MacOS) or development.bat (Windows) scripts. To do so, you need to install some stuf first:

1. Install node, nmp and socket.io.

   In Ubuntu Linux:

    sudo add-apt-repository ppa:chris-lea/node.js  
    sudo apt-get update
    sudo apt-get install nodejs
    cd vendors/KievII/comm/oscproxy
    npm install socket.io
   

   In MacOS with HomeBrew

    brew install node
    curl https://npmjs.org/install.sh | sh
    cd vendors/KievII/comm/oscproxy
    npm install socket.io
   

   In MacOS without HomeBrew (If you don't know/care what HomeBrew is), download and run the MacOS installer from here and then:

    cd vendors/KievII/comm/oscproxy
    npm install socket.io
   

   In Windows, download and run the Windows installer from here and then:

    cd vendors/KievII/comm/oscproxy
    npm install socket.io
   

2. Run it

   In Linux and MacOS:

    cd path/to/this/repo
    scripts/development.sh
   

   In Windows:

    cd path/to/this/repo
    scripts/development.bat
   

Tested in MacOS 10.7, Xcode 4.6 and iOS 6.0

Open the wrappers/ios/Morphasynth.xcodeproj project in Xcode and click Run.
