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.
⑪
Oscillator Frequency Control
Rough adjustment of the amplitude modulation (AM) oscillator frequency.
⑫
Oscillator Frequency Fine Adjustment Control
Fine adjustment of the oscillation frequency. Range is about 4 – 5 semitones (quarte).
⑬
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.
⑭
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.
⑮
LFO Modulation Depth Control
Amount of LFO modulation depth
⑯
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.
⑰
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.
⑱
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 .
