The Bonge, motivated
by the bowed string, consists of four bowed "sponges." Each "string" consists
of a small piece of foam-covered wood resting freely between two fixed FSRs.
Each "string" can be bowed, creating
a data point that depends on direction, pressure, and bow
speed; negative values indicate "up-bow," positive values
indicate "down-bow." When bowed with the R-Bow,
this instrument has eight dimensions: the four R-Bow dimensions
and the four "strings" of the Bonge. A microcontroller converts
the data to MIDI continuous control messages.
