I'm looking for randomize Note On from a midi file. I have two way for sending this file, a standard file generated by Lilypond or a text file by midicomp.

( 000 is a special case) I've googled some info about $RANDOM but I haven't been successful in my rather random! investigations. :) Have you any advice or pointers? Midiclocking regards. -- Phil.
