The plong sound he plays the melody with sounds exactly like the Akai s1000 default sound. You can here it clearly at 4.07. The bi-sound and all. Sounds exactly like the Akai S1000. I had one myself, actually I still have the sampler. Fully expanded with 12 Mb memory ...lol.
I will love this record until l the day I die. It reminds me of one morning, after a mad night,we sat on a hill outside London and watched the snow fall over the countryside. Beautiful.
