It does not matter Radek, it shows a lot of sounds used by JMJ and the way you play is not important. I already heard the works of Per Kristian Risvik about the D-50 and some Revolutions sounds, but this time, it is Live played and that is better IMO. Thanks for it.
However, I owned a D-550 and I sold it; Because of you, I now want another one (but the keyboard version this time)
But D-50 was also (and it still is) a great synthesizer, not only for Jarre sounds ... Far from it !!
I consider it regrettable that Roland did not leave yet virtual version of this mythical synthesizer, like Korg and its virtual M1 (with the Legacy digital edition) wich includes ALL the sounds from the expansion cards from this time ...
