Luppp is a live performance tool that allows the playback of audio while applying effects to it in real time. It aims to make creating and modifying audio as easy as possible for an artist in a live situation. At its core lies the JACK Audio Connection Kit for access to audio and MIDI, usable effects include LADSPA, LV2 and custom Luppp effects. There is a GUI built using Gtkmm, however it is encouraged to use a hardware controller for faster and more intuitive interaction.
