One other minor thing I notice with my HD500 is when I have a high pitch shift (More than +12.0), I notice if I play a single not it sounds fine, but if I combine notes together or have one ringing then pluck another one or play a whole chord, sometimes it tends to make the sound "pixelated or digital." I don't know if the example of the sound I provide makes sense. Basically if I have a high octave setting and play more than one note, it tends to sound bad haha. Like I said, minor problem, not a big deal.
PS) You guys are the best!! Thanks for all the help!
