To get samples from og404 to .wav file you can do this:
cancel+resample, then resample again to export, then the flashing pads are ones you can export, you CAN'T export patterns, only pads, so rip the beat into one pad somehow, then export it and you should have a wav file at the top of the file directory in the card folder

I sold my og404 years ago and have an SX now so hope that is correct info. You will love either unit for sure. I didn't really have a prob with OG 404 but wanted the new features and audio quality.
