Style Old Format Converter is a software program for converting YAMAHA keyboard style files in SFF1 style format to various subformats used at older/smaller keyboards.

To convert SFF2 format styles to SFF1 format use Style Format 2 Converter. SFF2 is also known as SFF GE.

Read about style format differences and how to convert between models at Style File Features.

The program can be run in 2 modes:
• Convert a single/multiple style files
• Convert all style files in a folder

During the years the Mega Voices have got more complex, and the number has increased dramatically.

This means that the conversion of Mega Voices in some cases is rather problematic; and hence an individual revoicing of the style might be required.

After conversion the style might need some tweaking:
• To revoice the style: Use the Style Creator at your keyboard or my Style Revoicer software.
• To edit the OTS data: Use the Style Creator at your keyboard or my OTS Editor software.
• To edit the MIDI data: Use the Style Creator at your keyboard or your sequencer program.
• To edit the CASM data: Use my CASM Editor software.
