Not true at all bro. It will take any size CF card. The limitation is that it will only read the first 512 files on a CF card. It doesn't matter if those 512 files add up to 1GB or 8GB.

 

Garnet Canuck is correct. I chose 4GB as a good middle ground. One of the posters here who is a DJ pointed out he has hour long mixes, so he got a larger card since each file is much larger. As a general rule, 2GB or 4GB is a good size.
