I have the latest version of nitrotracker on my edge ds card, with a 1gb micro sd (if that matters?) Basically, I can sample things alright through the microphone, and then make tunes and whatever, but I cannot load songs that I saved, and cannot load samples to use as instruments. I click on the tab, then on smp/sng, then on load, and nothing else happens. I am left with just a blue box (where the files to select from should be), and just a 'load' button in the left hand corner of that box. Also, how do I change the length of a note? Any help will be much appreciated. Thanks.
