M2TM Chords and M2TM Chords DV are two powerful tools that can assist you in creating simple or (very) complex harmonic progressions using Ableton Live and store your chords inside a MIDI clip.
Their smart parser recognizes chords all common (and not-so-common) chord symbols, with added 6th, 7th, 9th, 11th and 13th, in any order and in their natural, lowered (flat) or raised (sharp) variations, plus many non-standard chords like stacked fourths or fifths. It supports slash chords (eg Cmaj7/G), chord inversions, rootless and drop chords, open and closed voicings, and more.

Both generators offers the unique auto-inversion feature, that is is the ability to automatically select the best inversion for each chord in the progression, as an expert piano or keyboard player would do. If two consecutive chords have notes in common, the legato option can merge theme into a single, longer note (great for pads and string sections!).

You can build complex harmonies by generating one simpler progression at a time. New progressions can be appended to existing ones, and the auto-loop option can ensure that the clip's loop area always matches the most recent progression or encompasses all the sub-progressions generated so far.
