For Casio programmer , please upgrade OS 1.2 because :
1. Name file patern/style just 8 character, is very short, Yamaha can not 16 character.
2. Flashdisk cannot read new folder or multiple folder, just can read in folder MUSICDAT, I have many file by genre, need to separate by alfabet
3. sample voice wav, can not copy from another wav, just insert by record again, please can copy and need software same a yep file inYamaha
Actualy Casio is very the best facilty with cheep price.
Best regards.
