Forum:Ido vs summons

Quick, obvious question has come up.

If you have Ido the Supreme Magical Force on your field, it says you cannot summon monsters. However, I'm unsure on whether you can tribute it in order to tribute summon a higher level monster or not. Do you tribute a monster in order to activate the tribute summon (much like the cost of some spell/trap cards) or do you have to initiate the tribute summon in order to tribute monsters for the summon?
