Ingen is a modular audio processing system for Jack and LV2 based systems.

Ingen is built around LV2 technology and a strict separation of engine from user interface. The engine is controlled exclusively through a protocol, and can execute as a headless process, with an in-process GUI, or as an LV2 plugin. The GUI can run as a program which communicates over a Unix or TCP/IP socket, or as an embeddable LV2 GUI which communicates via LV2 ports.

Any saved Ingen graph can be loaded as an LV2 plugin on any system where Ingen is installed. This allows users to visually develop custom plugins for use in other applications without programming.

Ingen is currently only available in git. Since it requires a few libraries in the same repository, it is easiest to: git clone Either build lilv, suil, raul, and ganv first, then ingen; or simply build the entire repository (in addition to Ingen, you'll get Patchage and Machina). You will require a recent version of LV2.
