J74 BassLine is a plug-in for Ableton Live (Max for Live) specialized in bass line progressions. The key idea behind this device is to have a single, flexible tool for bass line programming which combines both rhythm and harmony together. In terms of rhythm J74 BassLine makes use of groove, swing, legato, glide, accent and humanize dynamics. From the harmony point of view the tool works having knowledge of scales, chords and progressions, combining these with the rhythmic pattern creation. The bass-lines get automatically adapted to the progression, on a chord by chord basis, remaining in-key to the selected scale (if you wish it to). This works at its best when J74 BassLine is combined with J74 Progressive (another J74 tool set), in Linked Mode. By combining the two tools you have a single, integrated environment for quickly sketching harmonic and rhythmic material in Ableton Live.
