Yes. That would be the "other" direction. Put electrons into a
crystal, it "squishes" itself (vibrates). :-)

I really don't know "which" piezio the Roland people are using.

I suppose it makes more sense to set the Piczas'tiny wire "probe"
vibrating, and pay attention when the vibration changes frequency
(because we touched something).

Thank you.
