The Filter Section (VCF)
The Pulse 2 offers a multimode filter.

A detailed introduction of the filters can be found
in the chapter "Sound Synthesis Basics" of this
manual.

We recommend to tune the filter periodically to
ensure settings reliability. Read more about this
in the chapter "Utility Menu".
Cutoff
0...127
Cutoff the frequency for the lowpass and highpass filter
type and the center frequency for the band pass.
•
When the lowpass type is selected via the Type
switch, all frequencies above the cutoff fre-
quency are progressively damped.
•
When the highpass type is selected, all frequen-
cies below the cutoff frequency are damped.
•
When the bandpass type is selected, only fre-
quencies near the cutoff setting will passed
through.
You can bring more movement into the sound by modu-
lating the cutoff frequency via the LFO, the envelope or
the Keytrack parameter of the filter. At 100% Key-
tracking and maximum Resonance level, the then self-
oscillating filter can be played in a tempered scale.
Resonance
0...127
Resonance is the emphasis around the corner frequency.
Use lower values to give more brilliance to a sound. At
higher values a sound gets the typical filter character
with a strong boost around the cutoff frequency. When
the setting is raised to maximum, the filter starts to self-
oscillate, generating a pure sine wave. This feature can
be used to create analog-style effects and percussion,
like electronic toms, kicks, zaps etc.
ENV F Mod
-64...+63
(= Envelope Mod Amount). Sets the amount of influence
the envelope has on the cutoff frequency. For higher
settings, the filter cutoff frequency is increased by the
modulation of the envelope. Use this parameter to
