dumbass semiconductor question

[media at mail1.nai.net]

OK, we all know that you can use an NPN transistor as a current controlled
switch that is normally open.  I'm trying to modify an ancient drum machine
for a friend that runs when the footswitch is open and stops when the
switch is closed (opposite than what you would think).

So what kind of gizmo can I use to the switch that will normally be closed
(not running) and open (run) when it receives a voltage or from a keyboard
gate or x0xbox sync??

It's 1AM and I'm just drawing a blank.

THANX!!

PEACE OUT :)

P.S.  Like how hard could it be to mail a fuckin' catalog??
