The optional USB interface board UIB-02 lets you connect the MRS-1608 to a computer (Windows or Mac) equipped with a USB port. Using the free Audio File Manager software, you can import and export audio data as WAV or AIFF files at high speed over a USB 2.0 link. Backing up project data or importing SMFs or sample phrases is quick and easy.
Sounds very easy, and if you can export in aaif and wav, it should stay as high quality of audio as you recorded...
