Notes about the W7S file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The W7S file type is primarily associated with 'Yamaha' by Yamaha Corporation. The MO Music Production Synthesizer is targeted to semi-professional musicians and home/project studio owners as well as songwriters and performers. The MO provides a full set of authentic sounds and comprehensive music-making features--including an emphasis on contemporary styles and voices. All the User Song data in this synthesizerís internal User Memory (DRAM) is treated as a single file (extension: W7S), and can be saved to a USB storage device.
