ARTURIA – CS-80 V – USER MANUAL 37
To select the sine, first validate that the linear ~ slider is lit and then set its volume with
this slider.
The square and triangle signals are affected by the pulse width settings noted PW.
The fader is used to choose a pulse width from 50% to 90%. This pulse width can be
modified by a low frequency oscillator (LFO). The modulation rate is set with the
PWM fader and the speed with the SPEED fader.
PWM Settings
Unlike the original CS-80 LFO where only the sine waveforms were available, the
wave can be set with the WAVE FORM selector. The waveforms available are sine,
saw-up, saw-down, square, noise and random.
This LFO can function in three modes chosen on the LFO MODE selector:
 FREE: all LFOs of each of the polyphonic voices function independently of the
others;
 TRIG: the LFO restarts at the beginning of its waveform each time that the
polyphonic voice is activated;
 MONO: only the LFO of the first polyphonic voice is used.
The latter allows us to bring a general effect to all of the voices at the same time,
like the original CS-80.
It is possible to synchronize the LFO speed with the tempo of the host application
with the MIDI SYNC button.
The signal from the oscillators then goes through two filters in a series, one high-pass
and one low-pass. The cut-off frequency and the resonance of each of these filters
can be set with the green and red HPF and LPF faders (above or below the labels).
