ARTURIA – ARP2600 V – USER’S MANUAL
•
Key follow (KYBD CV)
: Pre-cabled for the manual setting of the key follow
•
Oscillator3 sine (VCO3 Sin)
:pre-cabled for the manual setting of the modulation
by sine wave form of oscillator2
•
ADSR Env
: re-cabled for the manual setting of the modulation
by ADSR envelope.
It possesses a cut-off frequency setting and a resonance setting.
A setting separated from the notch filter frequency (Notch frequency) divided by the initial filter
cut-off frequency has been added. This very particular parameter (present on the module of the
ARP2500) transforms the notch filter to a low shell or high shell filter.
As for all other modulation inputs, once connected, its amplitude is set by raising the linear poten-
tiometer. With a right click, we obtain a higher level of precision. Receiving a modulation coming
directly from the output of a generator (envelope, oscillator, sequencer), the maximum amplitude
of modulation of +/- 9 octaves.
Only the cut-off frequency can be dynamically modulated by one of the 3 modulation inputs.
5.1.3.1 The filter types:
•
The low pass 24dB / oct Low pass (LP 24)
The low pass 24dB filter is typical of the ARP2600. It eliminates the frequencies situated below the
pivotal frequency (the cut-off frequency).
The low pass filter
The four other filtering modes didn’t exist on the original ARP2600 but existed on the ARP2500
modular systems. They all use a filtering slope at 12 dB/ octave. These modes were added to in-
crease the possibilities for sound creation on the ARP 2600V.
•
The low pass 12dB / octave (LP 12)
The low pass 12 dB filter is works in the same manner as the 24 dB/ oct. on the the ARP2600. It will
just give you a slightly different result due to the fact that its filtering slope is not as fast.
•
The high pass (HP 12)
The high pass filter is the opposite of the low pass filter. It eliminates the frequencies above the
cut-off frequency.
For a conventional key follow setting (in relation to the scale) place the potentiometer com-
pletely to the top.
