3.0 The sections of the DELTA CEP A in detail
3.1 LFO Section
The LFO ( L OW F REQUENCY O SCILLATOR) section of a synthesizer is the most
important and widely used modulation source. An LFO generates periodic modulation
voltages. The LFO of the DELTA CEP A can be tuned far into the audio range and allows
both MIDI and external clock synchronization.
Knobs and buttons of the LFO-Section.
Button Knob/Button Description
- - -
DEPTH The DEPTH knob adjusts the voltage swing of the modulation
voltage and thus the modulation strength. In the middle
position, the strength is 0. To the left and right, the strength of
the modulation is increased while the modulation voltage in
the left value range is additionally inverted.
- - - SPEED The speed control adjusts the speed of the LFO.
SHIFT
SPEED
If you want the LFO to sync to the current tempo, hold down
the [SHIFT] key while adjusting the Speed knob. As long as
the LFO does not receive external synchronization, the internal
tempo clock is the deciding factor for the speed. In this case,
you can change the speed by tapping quarter notes on the
[TEMPO] button. If you hold down the [SHIFT] key, you can
only select speeds that correspond to the printed note values
according to the current tempo.
