ahh it seems i finally got a stress correlation on a socket and worked that stuff over and it seems we've got reasonably close noise baselines except..on 5 where it's much quieter.... but it still does that thing where if you turn it ON...then it changes voltage there on the first hit then stays at zero roughly and never changes again! yet..the note..plays. I don't get it.

Anyway if I can figure why 5 isn't on after tuning I think we'll have it. I changed the CEM chips...no result. The op amp that does the vca...nothing..the 4051's...nope. If I turn 5 on it always sounds in reasonable tune. What in the world!? What ∗ELSE∗ does it check for before it turns the channel on?
