J74 Progressive is a set of Max for Live tools for chord progression making and harmonic editing in Ableton Live. Progressive allows you to create and edit chord progressions as MIDI clips, making use of composition techniques modelling (such as diatonic scale and chords exploration methods) as well as performance styles (arpeggio, humanized timing and dynamics). The tool is capable of producing extremely realistic chord progressions and arpeggios, delivered directly as MIDI clips in Ableton Live Session view. Besides the chord progression generator/editor, Progressive also includes tools for scale and chord detection in any MIDI and Audio material and for MIDI clip processing (harmonization/scale based transposition and humanize dynamics).

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). J74 BassLine can also be combined (and synchronized) with J74 Progressive for an integrated harmonic and rhythmic sketching environment within Ableton Live.

J74 ARPline is an arpeggiator plugin for Ableton Live (Max for Live). With a lot of flexibility. At its heart it is composed of four independent lines, each one capable of the same features. A line is a programmable pattern for triggers and has its own controls for step number, step offset, playback direction, speed, signature, probability and more. When settings are combined across the lines, these features allow you to create complex poly-metric and/or poly-rhythmic arpeggio's.

J74 HarmoTools is a set of devices for Real-Time MIDI harmonization in Ableton Live. The plugins detect chords and scales and can be used to adapt in real-time MIDI data to the harmonic context of your liveset, eventually in collaboration with other musicians using a TCP/IP network.
