ABSYNTH 5 Reference Manual – 79
The Main panel of the Frequency Shift mode contains the following parameters:
•
Directionswitch: If this button is on “+”, it produces frequency sums. If the button is on
“-”, the module produces frequency differences.
•
WaveformSelector: A click on the Waveform Selector opens the Waveform Selection dia-
log where you can select the Waveform for the oscillator.
•
FrequencymenuandFrequencycontrol: Enables you to enter the oscillator’s frequency as
a transposition of the played note (Trans), as a relationship (Ratio) with the played note,
as a xed Frequency (Hz) or via a xed MIDI note (Note).
• Feedbackcontrol: Adjusts the amount of feedback.
You will nd more in-depth explanations about the Waveform Selector and the Frequency
menu/control in the section 5.3, “Common Features in Many Modules”, above.

A light detuning between the input signal and the modulator signal combined with a mod-
erate Feedback value can induce a nice phasing effect. Very low frequency settings (e.g.,
1 Hz) can lead to similar effects.
Because there is no interference between sum and difference frequencies, the Freq Shift
frequently sounds cleaner than the Ringmod in situations involving complex input signals (e.g.
samples or saw tooth Waveforms).
!
Frequency shifting is not the same as pitch shifting. In pitch shifting, the Pitch Shifter multi-
plies the frequencies contained in a signal by a known factor: as a result, harmonic relations
between the frequencies remain. A frequency shifter, by contrast, attaches a known value to the
frequencies contained within the input signal, thus altering the harmonic relations it may contain.
