No sound in high velocity

[hleem]

My P6 keys just started to behave somewhat erratically.

It plays fine when it is played at low and mid velocity, but when the keys are struck at high velocities, it does not generate a sound at all.

It has been turned off (laying perfectly still, not being moved) etc for a few weeks. Keys work at low velocities so it's not a matter of sensors going bust from playing too hard, items falling on the keys etc.

Turns out the velocity response had changed to #3 while it was asleep…

There was a bug prior to the 1.4 OS for the Prophet 6 where velocity curve #3 was silent at the highest velocity. This was fixed with the 1.4.0 OS.
