Sorry for the delay, folks! Anyway, if you haven't checked it out yet, there's a new article at www.brainwave-entrainment.net63.net. Making An Isochronic Ramp<http://www.brainwave-entrainment.net63.net/index.php?pagex=making-an-isochronic-ramp.php&sb=specifics.inc.php> . BTW, there seems to be something in IE8 that messed up the site's layout. Firefox is recommended for viewing the site best. Thanks.
