72 ARTURIA – MOOG MODULAR V 2.6 – USER’S MANUAL
A connected oscillator is active and consumes calculation power. It is therefore necessary to verify that the
connected oscillators are in use. Similarly, a group of oscillators disconnected from the keyboard by the “keyb”
interrupter is permanently active.
7.1.3 Filters
The Moog Modular V possesses 3 filter modules. It is possible to choose one of four types of
filter for each of the modules: a low-pass 24 dB/octave (type 904A), a high-pass 24dB/octave
(type 904B), a band-cut and band-pass 24 dB/octave (type 904C) and finally a multi-mode 12
dB/octave filter. Clicking on the name of the module and selecting the filter from the menu
proposed does the type change.
All of these filters possess internal connections to simplify the use of keyboard follows,
portamento, pitch bend and sequencer.
To avoid having to manage the tuning of the keyboard follow with the amplitude of the
modulation input, with a display we can choose if a keyboard follow is to be used and which
one. This keyboard follow is done to get a correct pitch from the keyboard. Depending on the
configuration of the chosen keyboard follow, the portamento and the pitch bend will be applied
or not to this filter.
The functioning is the same for the sequencer outputs (1 to 4) controlling the tuning of the
cut-off frequency of this filter. In the “no” follow position, the filter is independent of the notes
played on the keyboard. In the same manner, set to the “no” sequencer position, the filter is
disconnected from the sequencer output.
It is still possible to connect a keyboard follow or a sequencer output to a modulation input
obtaining a tuning as fine as necessary.
