rev4~ cheap reverb This is a "cheap reverb" which is less CPU-intensive than rev1~, but which does not sound as nice. Both reverb units have a mono input with stereo reverb output. Since the two outputs differ only by phase content, one output may be used alone when monophonic reverberation is required.	from the library : Jimmies Format : Abstraction Environment : max / msp commercial Max 3.x / 4.x http://forumnet.ircam.fr//rubrique.php3?id_rubrique=65
