Carousel records

Hello!
Thank you for such a wonderful theme.
I encountered the following problem:
I want to hide the category number 1 records, so it’s do not appear in the main, but that they are displayed in the carousel. Hide category 1 with function:

function hidecategory ($ query) {
if ($ query-> is_home) {
    $ query-> set ('cat', '-1');
    }
return $ query;
}
add_filter ('pre_get_posts', 'hidecategory');

don’t possible, write to disappear along with the main carousel.
The same effect on the plugin Frontpage category filter.
Help me please.
