| Hi flat earth,
I played an early version Opera 6 (I believe it was a version with VCOs) every week at rehearsal in a Rome studio in the late '80s/early '90s, and I remember I liked it quite a bit: beautiful synth strings and powerful synth brass were its main features, but I also recall a distinctive electric piano sound. However, I also remember the velocity-sensitivity was hard to play, going from pianissimo to fortissimo without much control in between.
The DK-600 is an updated version with better MIDI, and DCOs.
As far as differences in sound, this is what I remember:
Opera 6 - PolySix: very different. The Opera 6 was more "plastic-sounding" if I can describe it like that, where the PolySix is more "liquid"
Opera 6 - Juno line: different from the 60; more similar to the 106
Opera 6 - AX line: different from the 80. I'm not familiar with the 60 or 73 enough to make a comment |
