Please help! I am a newbie to logic pro 9. I use the factory pre settings in the mastering section, to master my songs. I don't know how to master but the factory settings are helpful and I use them a lot. I accidentally deleted the Hip Hop wide master channel strip setting from the stereo output channel. It's completely gone and I can't restore it. I have a imac 27" i7 quad core with no external hard drive. If I load my logic pro 9 installation DVD's, what will happen? Will this restore the deleted hip hop wide master channel strip setting? Most importantly, will I lose my beats and custom drum kits I have created? I haven't tried anything because I'm scared I will lose everything I have saved in logic. Somebody please help me?!!!
