thanks for the tip.
i play bass in three different bands , soon to be 4. i just want a simple cartrige to restore the original sounds as i dont have much time to play around with an old synth at the moment. i have not looked into the sysex and really have no idea on what the steps are to doing this. the dx-7s was kind of a wierd synth in between the original and the dx-7II models, there does not seem to be very much info on patches out there. the original patches are similar in ways of programming, but they are not the same.
