So....the first 3 lines of my brain just reset to 100% when it's about 3% either side, so it's not floating around near 100%, flickering the LED in Mach. You could delete those 3 lines of the brain and the last two lines should do the FRO thing at 150%. It doesn't do that for you? You could change the formula to a/5.12 to get 200%. If those don't work, I have no idea. Works for me just the way it's written, FRO starts up at whatever the pot is set to, lives thru RESET, and moves to whatever the pot sets it to, and it jumps to 100% when it's around 100% +/- approx. 3%.
Again, the offer stands, upload your brain and I'll see if it works here, and take a look at it, for what it's worth. Can't hurt!
