If memory serves, the Poly 800 has MIDI dump capabilities. A simple dump would be easier to manage than a tape wave file. I remember having done the same thing on a friend's Poly 800; my DX7 was connected on it, and I accidentally dumped the memory. Korg's MIDI implementation was weak (buggy?) enough to accept the dump, and it reset everything. Needless to say my friend was rather moody for a while :-)
Hi, a friend of mine accidently erased his presetsin his Poly 800II. I am in need of a wave file of the original factory tape. If anyone knows of one, or where a copy of the wave file is on the net. Any help is greatly appreciated. Ron
