synthgeek Korg Poly-800 MkII fx sound samples
It was my first real synth (not counting the SK-1 I had when I was 12)- I sold my playstation & all the games I had to fund the purchase.
The download includes 7 samples of varying length, all 24 bit, 44.1kHz, stereo wave files.
Download them here.
Make sure to check the synthgeek pages for more cool samples.
