Oscillator Frequency High/Low Switch

Hi:

 ≈ 18Hz – 18000 Hz (Audio range)

Lo:

 ≈  0.15Hz – 120 Hz

In "

Hi

" position, the oscillator is working in audio range. The amplitude modulation e.g. 

will generate additional audio frequencies – sum and difference tones of the input signal 
and the oscillator frequency.

In "

Lo

" position, the oscillator is working with subaudio frequencies. The amplitude 

modulation effect is more like  a" tremolo" sound. Volume of the input signal will change 
constantly with the  oscillator frequency.

 

Oscillator Frequency Control

 Rough adjustment of the amplitude modulation (AM) oscillator frequency.

 

Oscillator Frequency Fine Adjustment Control

Fine adjustment of the oscillation frequency. Range is about 4 – 5 semitones (quarte).

 

Oscillator Waveform Switch

The oscillator waveform can be selected between sinewave and triangle. In "  " (sine) 

position, the effect is a more smooth sound with less overtones; in "

 " (triangle) mode the

generated sounds are rougher.

 

LFO Frequency Control

 Speed control of the internal LFO device (low frequency oscillator) for frequency 

modulation of the ring modulation oscillator. Frequency is from ≈0.06Hz (left position ) to 
≈ 44Hz (right position)

The LFO frequency is also displayed by the orange LED for easy visual confirmation.

 

LFO Modulation Depth Control

Amount of LFO modulation depth

 

LFO Waveform Switch

The LFO waveform can be selected between triangle (" ") and square ("   ")." " will 

provide a continously up-and down gliding pitch, while "   " makes the oscillator shifting  
between two tones.

 

Envelope Follower/ext. CV Modulation Depth Control

The internal envelope follower converts the volume of the input signal into a control 

voltage modulating the oscillator frequency. Amount of modulation can be varied by this 
knob.
If the external frequency CV (= Control Voltage) input    is in use, the envelope follower 
will be switched off and instead the signal on   will control the frequency and will be 
adjusted by this pot.

 

Envelope Follower Modulation: Inversion Switch

Switches the the modulation (from envelope follower or external source)  from positive to 

negative. If the switch is in upper position, the pitch of the AM oscillator will increase with 
higher volume of the input signal. switch in lower position (= "

Inversion

") the pitch will 

decrease with higher input volume. The inversion switch works also for a control voltage 
signal connected to  .
