I'm making a script for Renoise and would just like to invite you to come with suggestions or feature requests on this project. It's relevant for the chip community since it will (for one thing) be capable of converting chords to arps in very customized manners. It will also encourage rapid prototyping when it comes to arps (or any representation of a chord) in terms of their rhythms and rules. For example, you could generate an arp track (with arps behaving in a very specified way) by combining a guiding chord track with a rhythm/trigger track. What I've generated so far with the prototypes sounded pretty awesome and would be stuff that you'd be reluctant trying to track by hand.
Have a look if you find this interesting and feel free to come with suggestions: https://github.com/snabeljoel/Chord-manipulation-model
Feel free to question whether it would be capable of doing X or Y since that could provoke me into implementing more features!
