One working design for such circuit can be found at

That's one option if the desk has suitable chase etc.
Stroboscopes normally want a control input which is 10V pulse
applied to the input when it is wanted to flash. A normal
slider will output adjustable 0-10V DC which does not
as such make the strobo flash constanly or control it's speed
(unless it is a very special strobocope). If you pull the
slider to 0 and then press flash button on deks, you can make
the strobo to flash. If you turn on a chase whcih flases the output,
you get strobo to flash.
