Logic Pro - Chord Memorizer: similar functionality with Max For Live?

Hi,

After reading this tutorial http://rurl.org/269s I was wondering if there is a tool like Logic's Chord Memorizer realized with Max/Max4Live?

With the chord midi-effect in Live I can only assign the same chord structure to all keys on the keyboard - right? I'm looking for a way to assign one or many (then triggered e.g. by velocity control) distinct chord structures to each key on the keyboard. Could be very inspireing when you then connect that to a random object, a step sequencer or an arpeggiator.

New to Max I don't know if there is already anything similar out there.

If not maybe some of you guys would like to team up with a total newbee to realize this idea in Max?

Cheers,
Alex
