[korgypark] MIDI signal inducing noise using 05R/W serial connection

Working on a solution to this now, but I'm told it's due to excessive serial 
voltage coming from the PC to the Korg, then bleeding into the audio stages 
back to the PC.

I've found that padding the volume level back to the PC (if you have a mixer 
running between the KORG and your soundcard's line in) will help a ton in 
minimizing this (note:  the physical volume knob setting on the KORG has no 
effect on reducing noise and should be maxed out to maximize signal to noise 
ratio, as well as setting the MIDI channel volume setting to 127).  Also, 
using the headphone jack instead of the 1/4" line outs dramatically lowered 
the serial noise!

I will follow-up if I fix this.
