Touchplate Keyboard

Multifunction Keyboard Module

DETAILS
The biggest part of the module is a keyboard with 32 touchplates in the usual piano arrangement. The keys are trimmed to 1V/octave and generate four signals simultaneously when touched: note CV, pressure CV, gate and a 10ms long trigger.
To be precise: not the pressure is measured but the amount of skin touching the keys.
Three touch plates in the upper right are used for octave transposition; the active touchplate glows red.

In the upper left there's a bender: one touch plate generates a negative voltage, the other a positive one. The voltage is wot added to the big keyboard's note CV but is available at an individual socket.

Centered is another keyboard which is not 1V/octave. It has eight touch plates, each of which can be tuned freely. Use it for recalling fixed voltages (presets) or a as a microtonal keyboard. Besides the CV these touch plates also generate pressure and gate. The active touch plate is illuminated by a LED sitting behind the perforated plate.

CONNECTORS
