mixer options for using SW live

[Louie Angulo <louie.angulo@googlemail.com>]

Hi gang,
in dealing with my RME soundcard and laptop with ableton i realize
that having instant access to a master level and a panic mute button
is crucial,the RME 400 is nice but scrolling for the master level
could get dangerous playing live,and there isnt a physical mute button
on the front either.
So what would you recomend? there are some many options outhere,like a
controller to control the RMEs total mix virtual mixer,a simple nano
patch,and all of the hardware stuff to control ableton like the akai
APC 40,launch pad etc. but since i dont have much experience with this
i rather hear your opinions.
also is it possible to use the RME as a stand alone mixer without the
computer and use a controller like a BEHRINGER BCF 2000 for ex?
thanx
