Trautonium / Ribbon Controller

A-198

1. Introduction

Module A-198 is a so-called Trautonium resp. Rib-

bon Controller. It provides variable Control Voltages

and Gate signals generated by combined

position /

pressure sensor. The controlling element of the A-

198 is a linear position sensor (length about 50 cm)

that has available a pressure sensor too.

Touching the sensor with a finger generates a Con-

trol Voltage

that is

proportional to the position of

the finger. The Scale - i.e. the relation between

position difference and voltage difference - is ad-

justable

with a potentiometer at the front panel. A

Hold switch is used to determine if the CV voltage is

held after removing the finger or if the voltage jumps to

0V. In the last case (Hold = off) a

Gate

signal is

derived from the CV voltage whenever a finger tou-

ches the sensor (e.g. for triggering an Envelope Gene-

rator / ADSR).

A pressure sensor made of conductive rubber arran-

ged below the position sensor generates a

second

Control Voltage that increases with higher pressure

of the finger. Even for this CV the Scale is adjustable.

second Gate

signal is triggered as soon as the

pressure exceeds a certain value. The Gate Thres-

hold is adjustable at the front panel.
