I've never found any Clavinova PC utilities (for Windows). It seems that all my hard work and my old sequences (from CVP 55, 75, etc.) will be lost forever. Now that I have a CVP103, I KNOW that it doesn't recognize the ESEQ sequences as it should. Since nobody cares about a 100% conversion software, or at least a ESEQ editor for Windows (I talked about it with Yamaha USA, Giebler.com, Yamaha Japan...), I must do the sequences all over again in the new CVP (until they decide to "improve" to a new model, wich will be incompatible with the one that I have right now).
