Here is some stuff from Harmony Central

"One KARMA pattern can be used in Program mode. Four KARMA patterns can be used in Combination/Sequencer/Song Play modes, so that separate patterns can generate independent phrases to play different sounds such as drums, bass, guitar, and piano to create a full ensemble.

The basis of the phrase or pattern is called a Generated Effect (GE), and it controls how note data from the keyboard is developed. With approximately 400 parameters in a single GE, the KARMA function can control virtually any type of tonal or phrase change. These parameters include elements like harmony, scale, ad-lib/humanize, rhythm randomization and complexity, phrase variation, tone, pan, effects, pitch bend, volume, velocity, duration, MIDI control changes, chord control, MIDI delay/repeat (Melodic Repeat™), and pitch change.

Up to 16 of these parameters are available for real-time control over a GE, and can be adjusted by operating the eight Real-time Control knobs and two switches. Two available scenes allow controller settings to be saved for instant recall. Four Chord Buttons are also provided to allow the user to easily create and trigger complex voicings. The KARMA Music Workstation provides over 1,000 different GEs organized into 17 categories, and new GEs can be loaded as they are made available. "
