Hi Tapas: GOOD question. It appears (as far as I know) that PSRREG may be the best currently available REG program, but unfortunately it doesn't allow you edit all the custom settings available to be stored in Registration. Perhaps you might be able to convince resident Yamaha PSR/Tyros programming expert, Michael Bedesem, to come up with a program that would allow us to edit ALL the parameters (for style, voice, tempo, transpostion, multipads, etc) from the PC. I too would find it a very useful utility program. - Scott
