Jacktube is an audio/MIDI processing program. It uses LADSPA plugins to process audio, MIDI events to control its operation and Jack is used for audio connections. The exact operation is governed by a set of customizable rules.
Even though Jacktube is primarily meant for audio work, it can be used in any signal processing application.
