Have you considered replacing the microswitches?

They are brand new cherry microswitches and it iis happening with ALL of them.
I wrote Andy and he is sending me a new main chip. He said in May (when I purchased mine) he had a bad batch. Hopefully that will fix the issue.

Only other option is when you checked by using other grounding, did you use grounding that was wired straight into the end? (i.e. connect the grounds directly with a ground coming off the pc power supply?)
Are all the grounds in one big loop, or do you have multiple series of loops?

The I-Pac2 provides a player 1 ground and a player two ground, I used both with two seperate daisy chains.
The problem exists on both player 1 and player 2 keys.
I tried adding an additional ground wire from the I-Pac2 to the individual buttons, as well as from the end of the daisy chain to the beginning of the daisy chain to make it a full loop. Nothing made a difference.
Andy at Ultimarc seems pretty sure that I have a bad I-Pac2. Evidently he had a bad batch of chips in May, and I purchased mine on May 16th.

What I was suggesting was, if you have a spare pc power supply plug, run some ground wire to one of the black wires on them, and see if the problem persists. Also, is the wire go directly from the buttons to the ipac? Is there anything in between? (Such as an ethernet cable setup like Doc's modular.)
