ARTURIA – PROPHET V - MANUAL

Low pass filter 24dB/octave slope
The Prophet 5 employs a low pass 24dB filter. It eliminates the frequencies found above the
cut-off frequency.
The resonance amplifies the frequencies close to the cut-off frequency. The amount of
resonance is altered by adjusting the resonance knob. When you turn the knob to the right, the
filter becomes more selective; the frequencies found around the cut-off frequency will be
amplified and the sound begins to whistle.
Attention!
For more precision when setting the cut-off frequency of the filter or the resonance rate, right click on PC
or CTRL + Click on MAC. This can be useful when you wish to set the level of the cut-off frequency.

Amplifier
The amplifier is the last step in sound creation. It allows you to set the general volume of the
Prophet 5.

Envelopes
The two ADSR envelopes allow you to develop one or several time function parameters
.
You will find two envelopes on the Prophet 5: one controlling the cut-off frequency of the filter
(as well as the frequency of oscillator B) and the other controls the volume amplitude.
The ADSR envelope is composed of four successive sequential periods: Attack time, Decay time,
Sustain voltage, and the release time. When you send the signal for the note (by pressing the
