OK, at least the resitance goes the right way round i.e closing it
lowers the resitance.  The Yamaha peadal has a 150k resistor in series
with the tip.  It also has 10k, 47k, 150k resistors which it
progressively shorts through a 1k to the ring.  So, what you have
found by connecting to the ring rather than the tip makes sense.  

I suggest you try adding a 1k resistor in series with the ring to the
Yamaha and connecting the Roland tip to the Yamaha ring.

I am not sure what to do with the Roland ring - it depends on what you
measure.
