ARTURIA – ARP 2600 V – USER MANUAL 72
The ARP 2600 V offers two types of slope: 24 and 12 dB/Oct slopes.
On the ARP2600 V, you have access to four types of filtering. Let’s have a look
at some of his properties:
The low-pass filter (LPF) progressively removes high frequencies above the
assigned frequency limit (the cut-off frequency) and allows the sound below
the cut-off to pass through unchanged. Depending on the setting we will hear
the sound becoming more or less “brilliant”, more or less “dampened”.
This is the type of filtering that you will find more often than not on synthesizers
that use subtractive synthesis. It can be found on most of the recent analog
and digital synthesizers.
Spectrum of a noise signal proceed with a low-pass filter
The high-pass (high-pass filter or HPF), as opposed to the low-pass, eliminates
low frequencies and only allows high frequencies past. The sound will thus
become “thinner”. It is very useful for removing redundant low frequencies.
