CP-GFX ~ Cross Platform Guitar Effect Processor


CP-GFX is simply a Cross Platform Guitar Effect Processor. The aim of the project is to create an extensible and easy to use program which is easy to port to different platforms and operating systems. Currently in development are Linux x86 and Win32 builds.

For the Linux build the primary audio API in use is JACK, which allows CP-GFX to work along side and with other programs, such as Ardour, or any other software using JACK without any fuss or problems.
