This is a Korg Trident Mk ii 2 cassette tape back-up. Maybe right click to access download option
I cannot recall if it is the original factory soundset, or whether it contains some of my own creation too (likely!)
If you download the WAV file format and connect your device output to the cassette tape input of your Trident, you should be in a position to start the recovery process (assuming you don't have sounds)
Feel free to download it and keep. I miss my Trident!
I also have some manuals for the Sequential Pro-1 and Roland SH-101 etc. I will upload those soon.
