Fumbled Fingers Chord is like the Chord Midi Plugin from Live except that it allows the added notes to have delayed times and varied velocities. This includes min / max ranged random values.
The idea is to provide a more 'human' chord where not all the notes are hit at exactly the same time. Note, besure that quantize midi is off if your recording the midi output as it may push the midi notes back in place. In general, smaller values for delay work best for slightly humanized chords while higher values tend to be some what extreme.
Velocity values will be clipped to the range of 0-127 so as to not exceed standard midi values.
The randomize note length applies the randomized delay value to the length of the notes as well.
