Virus KC loosing output

    Hello I just got a second hand Virus KC to play with this weekend before I buy it. Overall it looks good but I've encountered a random issue where all of a sudden I lose sound and it's just a making this low level resonance sound.
    The only way I can fix it is by restarting the Virus.



    Any idea what it might be?

    If the unit has OS 6.5 installed, then this could point to a hardware problem, especially if you are anywhere near exhausting the max. amount of voices the unit can produce. Especially when playing it by itself and no other external unit being able to send any Midi CCs or SysEx to the device, this would point to a hardware issue.
