Everything is excellent except the polyphony can be a fair bit ...
Config quite simple, manual clear.
The sounds-like "analog" are really beautiful, with top quality multi-effects Intgr (not like Nordlead 1 and 2 that I sold quickly). All catgories sounds are excellent, leads to ground through the arpges, everything is perfect. In multi-timbral sound effects associated with that found in single mode is transmitted via MIDI and is rare enough to point out, in a gnrale multitimbral synth does not allow associate diffrent effect for each sound.
I had a C Virus that I sold to a KB because I needed a keyboard and between B and C there is almost no diffrence. The KB and a beautiful synth, sound, and full rev.
