So far, I think there's been no further discussion on this problem.  Yamaha
failed to include an aftertouch sensitivity in the global configuration,
therefore it spews out a lot of aftertouch data way to early (imho) for the
average keyboardist.  A schematic would be very handy in this case, because
I'm afraid that the only (simple) solution is to add a resistor in series
with the aftertouch strip.  Otherwise, you'll have to adjust the aftertouch
sensitivity on all of your outboard gear, which in reality is the simplest
solution.
