For Linux and Windows users, download the ZIP file and unzip it. Inside of the bin folder you will see a "blue" script for Linux or a "blue64.exe" file for use on Windows. (A 32-bit version, "blue.exe", is also included for those using an older version of Csound that is compiled for 32-bit Windows.)

Note: After starting Blue, you may want to explore the example projects and pieces found in the Blue/example folder (or right-click and explore contents of if on OSX).

Platform Specific Notes

The section below has notes for individual platforms.


Blue uses the right mouse click often to show popup menus. If you do not have a right mouse button, you can use ctrl-click for all "rt-clicks" that are mentioned in this documentation.

To make use of the function key shortcuts (F1-F12), you will need to go into System Preferences, choose Keyboard, then enable "Use all F1, F2, etc. keys as standard function keys".


For 64-bit systems, you may run into issues when running Blue with the API enabled where modifying widget values is not reflected in performance. This is likely due to the Csound Java API being compiled with SWIG < 2.0. For example, some older versions of Csound in Debian for amd64 is compiled with SWIG 1.3.0 and does not work with Blue. To work around this, you can install a newer version of Csound if available (i.e. from a testing repo), or compile Csound yourself and ensure you are using SWIG version 2.0 or greater.
