A bass synthesizer / sequencer combination produced by Future Retro. The 777 is based on an emulation of the Roland TB-303 bass synth, but adds a number of features, including a panel layout that is much improved over the 303, and a more capable sequencer. It also has both MIDI and CV/Gate interfaces, and a built-in MIDI-to-CV/Gate converter; it can sequence external synths using either interface. It was produced from about 1998 to 2008; Future Retro ended production after producing exactly 777 units.
