i will answer your question seeing as this is your first post and you just joined today but before i answer, i just want to say something:
sparq wrote:please do yourself a favor, before you ask........ search . 8 times out 10, your question has been asked. if after you search and don't find your answer, please make sure that you post in the proper forum. (i'm not saying you don't do this already) and just because a person wants to talk about national/international politics, it doesn't mean you post in the 1k section just because you have a 1k.
i said all of this because, following this rule, you will get less people trying to clown you and more people trying to honestly help you.
now, to your question..... the reason you still need a CF card is because your extended memory (128mb) is your work space. you load and save your work on the CF cards. if you are working on a beat and did not save your work b4 you turned the 1k off, you will lose everything you just worked on. the 128mb is just a temporary space to do your work.
i think this will be as simple of an explanation that you will get.
