I just bought a Poly 800. It came with the factory preset tape. It appears to have been re-programmed, and it will not take the data from the tape. I've also tried using the .wav files available on the Net, to no avail.

DCO1 gives sounds, but each signal (chords or single notes)goes up in pitch after 2 seconds. DCO2 doesn't seem to work at all. I've made sure that the octaves are on. Also, most of the values for the presets don't match what is on the preset guide on the face of the keyboard.

Any input would be greatly appreciated.
