Module A-198 is a Trautonium Manual resp. Ribbon Controller. The controlling element of the A-198 is a linear position sensor (length about 50 cm) hat has available a pressure sensor too.

Touching the sensor with a finger generates a control voltage CV1 that is proportional to the position of the finger.

The scale (i.e. the relation between position difference and voltage difference) is adjustable with a potentiometer at the front panel.

A hold switch is used to determine if the CV voltage is held after removing the finger (hold = on) or if the CV voltage jumps to 0V (hold = off).

In the last case (hold = off) a gate signal is derived from the CV voltage whenever a finger touches the sensor (e.g. for triggering an envelope generator).

A sensitive pressure sensor located below the position sensor generates a second control voltage CV2 that increases with higher pressure of the finger.

Even for CV2 the scale is adjustable.

A second gate signal is triggered as soon as the pressure exceeds a certain value. The gate threshold is adjustable at the front panel.

The sensors are located in a separate metal frame (length about 600 mm, width about 30 mm, height about 18 mm, weight: about 900 g, color: silver-grey).

The connection between the module and the sensor frame is made by a 4 pin cable (same as used for USB connections).

Typical applications:

- Trautonium manual, the string is replaced by the position sensor that is much easier to use and cheaper than the string. In combination with the Subharmonic Oscillator A-113, the Trautonium Filter A-104 and some auxiliary modules a complete Trautonium replica may be realized. In combination with the Quantizer A-156 exact semitone intervals are possible.

- Ribbon Controller for any A-100 parameter (e.g. pitch, filter frequency, loudness, panorama, speed, modulation depth and so on)
