Avantgarde Sound are celebrating their new small site, and users can get enChord at 10% off.

enChord v1 (for Lemur) is described as "the harmony modular super algorithm, a 21st century MIDI control super instrument". It is a controller that lets you design harmonically perfect chords and chord progressions using all scales with the aid of one-touch chord progression/scale modulation analysis for you to compose or perform (w/ PadBoard and TileBoard MIDI controllers).
