2. Functionality And Controls

Explanation of the controls:

1) Switch for octave selection:
0: Pitch range: ca. F1 to c2
1: Pitch range:: ca. F to c3
2: Pitch range:: ca. f to c4

2) Coarse frequency control:

The coarse frequency control potentiometer has a pitch range of about one octave.

3) Fine frequency control:
The fine frequency control potentiometer has a pitch range of about 1/3 octave.

4) Dynamics control:
The dynamics control poti changes the dynamics characteristics of the manual.
Poti to the right: direct response – short stretch for full volume
Poti to the left: fine dynamics control – longer stretch for full volume.

5) Trimpot for String adjustment:
If to apply a new string, or LED7 shines green or brightly red without pressing then you have to adjust the string:
(Adjustment see: Service And Maintenance)

6) Trimpot for scale adjustment:
Use that pot to adjust the distance between the octaves on the manual.
Normally the distance between the octaves is adjusted to 18 – 19 cm - depending on the players fingers and
special wishes. After changing the scale, you have to re-arrange the auxiliary keys to the new pitch.
(Adjustment see: Service And Maintenance)

7) Duo-LED (red/green):
Without pressing the string the LED should shine slightly red or being off.

If LED shines brightly (red or green) without pressing the string, you have to adjust the string using pot 5).

If string is pressed the LED should shine green and shows the GATE signal.

Explanation of the controls: (continued):

8) Volume Control for Sawtooth: The sawtooth generator has – like filter 1 and filter 2 – a separate volume control.

So the volumes can be adjusted to the same level when changing the output source. Up to 80 % it works like a

normal volume control. If set higher it will go into distortion mode for getting some non-linear distortion to
produce some more sound variations. The volume control only is active if the sound selector is switched to “S”.

9) Pre Filter Switch:
If in middle position, the sawtooth signal goes unchanged to the output and the formant filters.
If switched up or down you can add a passive low pass filter working at 100 Hz or 500 Hz. This is sometimes
used to make the sound a bit like a sinus, to produce some flute like sounds. The passive Filter also has

influence on the formant filters.

The controls 10) to 14) are the same for Filter 1 and Filter 2

10) Filter volume control:
Up to 80 % it works like a normal volume control. If set higher it will go into distortion mode for getting some
non-linear distortion.

11) Control for filter frequency:
For adjusting the cut-off frequency. The range can be changed using switch 13).

12) Control for filter resonance:
Filter1 is set up a bit sharper then Filter 2. So you can get Filter 1 to oscillate with high resonance and high filter
frequency. Filter 2 is a bit smoother and will not oscillate.

13) Switch for cut-off frequency range:
You can switch between two frequency ranges: 640 Hz and 6 kHz.

14) Bandpass (BP) / Lowpass (TP) selector:
