As a Hi-Res audio recorder, Roland R-07 has added a features by updating its firmware v1.1 such as USB audio on PC or iOS which allows listen PC or iOS audio via R-07. The R-07 can be listened wire and wireless headphones Simultaneously, and also via built-in small speaker.
The new firmware has improved the data transmission speed from 700k/s to 1.5mb/s which is interestingly lower than normal USB2.0. Hopefully Roland will release a new firmware to fix it.
