As of 2007, Elation hadn't actually developed the foot controller for the 192. See:

But using a midi foot controller would probably be a better option for you whether or not an Fc192 were available.
I use an FCB1010 with my Magic 260 to control a few things, but it is of very limited use:

I'm not aware of a foot board that is more flexible. A Korg padKontrol has great flexibility and would be able to anything you need, but not with your foot.
I use my keyboard and an iPad (with the midi surface ap) much more. If you have a keyboard with programmable button (I used the trigger buttons on a Korg M-50 to great advantage). As good as the M-50 is, I'm going to switch from the iPad to the padKontrol as soon as I can figure out how to mount it in my rig so that I can easy punch a button while I'm playing the keyboard - the padKontrol will give me easier access to more options than the iPad does.
