Brazzy, Thanks for responding. I've been pretty much doing that the same way. However, I like to have a good selection of favorite backing tracks on hand for quick playback (i.e.: live playing). Swapping out 2GB cards is a possibility and I find hooking up a separate MP3 player for this task a bit of a pain. And you have to redo your control settings per backing track every time. Like many older SD interfaces, I think the SD on the Spider Jam can't handle HC because of the FAT 16 formatting. I ordered a 4GB non HC SD card and will test my premise and report back. Nothing ventured, nothing gained !
