Rubber contact strip for synthesizer keys, 13-note strip. 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 play 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. This replacement contact strip is Roland part numbers 04230845 and 03456867.
