this would be very convenient to use for song writing purposes, mobile sample recording, practice, and demo recording. but i doubt it can yeild hi-fi recordings since the storage media is only 128 MB in size. this means that the unit probably uses heavy data compression to make 4 tracks of audio fit into such limited space. i used to record on a roland vs-840 loaded with one 100MB zip drive. my problem was that my recordings were not as detailed as commercial releases. when i shifted to better A/D's and higher recording rates, the details started to blossom
