Diki, not a problem with Yamaha's onboard USB recorder. Everything is recorded directly to the USB drive, as a .wav file, it is automatically saved to the drive when the recording ends and I have recorded entire performances with no drop-outs.

The main reason I used this was critique my performances while I was driving home from the jobs - great device and produces incredible, high quality recordings that can easily be edited using Audacity.
