For me it all started with 2-01 "DIGITAL NATIVE DANCE" and "BUZZ RISE".

My first two keyboards were Yamaha DX7 (Middle name and Roland D50.
It was back in 1988 when i came across them in a little music store. I bought them the same day, just after a few minutes of checking them out. Even though they were very different machines, together they produced very impressive sounds (especially when layered or overdubbed ). I also found that eventually it was almost unimaginable to use one without another. DX and D50 took care of most 1980's sounds and to my opinion were the best! I still have them and believe it or not, I still use them too (with a bit of FX of coarse). I programmed the two to death - my sound library is H U G E !
And even though I have a lot of other synths and a big recording studio; there's just something about D50 pads and DX punchy, metallic textures that keeps me coming back for more! I also think that they are the most reliable, well-built keyboards ever made. They are still (after over a decade of being heavily used) in perfect shape. No wonder big bands like "Rush" still use them on their tours!
