rr is a new Max Package consisting of a small collection of patchers designed to facilitate the generation of sequences of MIDI notes and control change messages characterized by various degrees of randomization and/or by transitions between defined start and end states.

Its constituent objects may be used to:

quickly and flexibly generate accelerating or decelerating sequences ('ramps') of MIDI notes, alongside optional control change messages for concurrent gradual transitions from one parameter state to another
generate SEQUENCES of accelerating or decelerating ramps of MIDI note and control change messages, varying their characteristics at random within defined limits
continuously generate MIDI notes and optional control change messages at random, within defined limits, with options to 'lock' parameters to vary in proportion with one another
