I'll start out by saying that I understand this is just a effecting the left channel for now, I know I know, one thing at a time lol. It seems easy to see how the code could be copied and adapted to the right channel just below this one when it's figured out, however the insertion of this code has resulted in the following...
We now have just a row of dashes sitting 2 pixels up on the first row, making the gap between rows appear bigger than it should and the peaks on the left channel are still confined to that row.
