NATURAL TOUCHBOARD CONTROLLER AND PROGRAMMER



This is a versatile and  ergonomic touchboard controller : the simple lay-out allows a lot of possibilities.

The fingering is also very natural :

                           LEFT HAND          RIGHT HAND

Thumb            :      touchpad 8             touchpad 9

Index  finger    :      touchpad 7             touchpad 10

Middle  finger  :      touchpad 6             touchpad 11

Thumb             :      touchpad 5             touchpad 12

Index  finger     :      touchpad 4             touchpad 13

Middle  finger   :      touchpad 3             touchpad 14    

Ring  finger       :      touchpad 2             touchpad 15

Little finger       :      touchpad 1              touchpad 16  (circuit is always ON)

Palm                :      2 pressure pads       2  pressure pads

There are 2 x 8 potemtiometers for selecting step voltages : the circuit uses analog  Multiplexers and Demultiplexers chips for processing the individual voltages according to the individual gates touchpads depressed (see truth table)...

In addition, there is an 8 Channel Light Joystick using Cadmium photocells, 2x4 Infrared LEDs /Detectors for other complex gating purposes and a ribbon controller..





HOW TO CONSTRUCT BUTTON  PADS

Hereunder  are some examples  on how you can construct gating button pads using audio/video tapes  as resistive elements.
