Is there a soundcard in my iBook

Sorry if this sounds stupid but is there a Sound card in my iBook and is it compatible with midi?
Will I be able to use a MicroKorg as a midi controller to use with Logic Express and Garageband?
Thankyou

yes there is a sound card, but no midi in or out puts. you will have to buy something like an external interface. BTW this should be in the audio section. hope this helps.

Ok thanks for your help and sorry for posting in the wrong place
