the resistors idea is interesting, but I've pretty much confirmed that the arduinoboy hardware is fine because the MIDI test sketch you sent me worked properly. I've looked up crosstalk and it seems arduino occasionally has this problem. why it wold consistently happen to me and no one else I can't figure out but it seems that these inaccuracies can be solved by going into the sketch and taking multiple samples at Analog In and then averaging them, which I'm gussing the arduino can do even many times while the GB is sending one serial bit. this is going to be Fun, as I have very limited experience programming the arduino. but the plan is simple. find all instances in the sketch of analog reads, and apply some kind of multiple checking and average the results. but if that's not the problem I'll have done it for nothing and still not know what the problem is...or why it went wrong for me in the first place
one thing I did notice is that one of the conductors of the Link cable measures 1~2 ohms while the rest read zero. I want to try this out with a different link cable but I'm hesitant to cut up my only other good one so I'm looking for an F-1 Race Quad splitter to cannibalize for the port. does that port have all the conductors I need?
also I was thinking what if the analog ins were made #1, #3 and #5 or #1, #4 and #6 so the inputs were more spread apart but they still run pretty close on the PCB so that probably wouldn't make much o a difference.
