The Origin mis-triggers very badly or does not trigger at all....meaning some voices would play while others never played. The speed to which I played did not alter the mistriggering.
Also, if you played the samed note several times in a row, all the voices would be used up and then no more voices would play.
I scrolled through several patches to see if this problem was patch-related, but the mistriggering was evident on any patch.
