Hi All, I am just switching to Linux and am trying to find something that can make my Casio CTK-671 keyboard work. It has no buit-in rhythm programming but rhythms can be downloaded into it through MIDI interface. These are available for download from Casio music web site http://music.casio.com/e/671/ But there is no software that allows you to compose the ones of your own. Not to mention that there is no Linux version of the software. There is a 60-page MIDI manual however http://ftp.casio.co.jp/pub/world_manual/emi/en/ctk_671/midi.pdf and Windows version of the downloader: http://music.casio.com/e/671/before.html With these I hope I will be able to figure out how to program and download rhytms into the keyboard. I wonder however is there is a standard protocol? Do you know of anyone who ever tried to figure this out? It makes sense to learn what others have done so far before starting a new project. I would appreciate your help and any information that you may have. Kind regards, Lex
