|Rubber contact strip for synthesizer keys, 12-note
strip. (If you need an 8-note strip, you can cut this to fit.) This rubber strip contains carbon contacts inside each "bubble". When a key is
depressed, the key presses down on the bubble, and the carbon makes contact with the
keyboard contact board. This type of strip has two contacts per note; one
is to trigger the note itself, the other is to indicate the velocity at which the note was struck.
Most keyboards use 12-note strips for each octave, with one 13-note strip at one end.
