Phil replied: that's a great document, a part from that twique. I have also
found that speeding up
the menus twique is a good one too!

one of the dancing dots systems that I set up had this setting on them, as
well as the paging settings and visual performance settings.
Phil replied: the pageing and visual performance are good twiques to do. Noel
is a good guy and his
article is definitely worth a read.
By the way, if any of you are uing MOTU gear in WDM mode then, you will want to
change this setting
in the wave section of your Aud.ini file.
