The XY position of the performer's hand contact moving onto the surface of the fabric is transmited to a computeur via a 12 Bytes resolution Midi card. This allows 4000 by 4000 points resolution.
Two conductive fabrics are fixed on a frame, each one weaved with conductive threads in a different direction. When the performer presses any point of the textile instrument, the upper layer connects with the fabric underneath and the current eletrical value is sent to the computer.
