Impulse Response Not Working

HI All
I have Cubase Pro 9.5 and I am trying to use Impulse Responses.
I press the Monitor Button but when I change from one IR to a different one they
sound the same.

My Interface is a Focusrite Saffire Pro 14 Firewire.

Can anyone help with this please.

Trying to use the IRs where? Using what? A few more details would be useful.

Sorry - I was using my Focusrite Pro 14 Interface and although I pressed the monitor button they didn’t work.

I have since changed to my Roland Duo Capture and I now have them working thanks.
