Definitely, your idea was great. Is there any chance to get Measure as it is implemented on the XO-1.5 running on the XO-1(with a reasonable effort)? 
This actually would solve the problem, at least for the workshop where I'd like to use it.
It would be so much cooler if the kids could actually see what they are doing than just poking around.

You mentioned needing to adjust the output volume by trial and error to not distortion — have you tried running the Measure activity? I think you should see the line-in input waveform so you can check for clipping (sorry can't test, only have one XO with me here at the moment).
