PULSAR • 23 USER MANUAL
SD (SNARE DRUM AND CLAP) SYNTHESIS MODULE
The SD synthesis module is focused on producing the sound of a snare
drum and a clap, while remaining, like all Pulsar sound modules, flexible
enough to synthesize a wide palette of sounds that goes far beyond
the classical snare drum. The heart of this module is a noise generator
of original design with a controlled spectrum, which largely determines
the characteristic sound of the Pulsar snare drum.
TUNE
knob — adjusts the spectrum of the noise generator.
MOD (near the TUNE and AMT knobs) pin — CV input for controlling
the noise spectrum.
AMT
(amount) knob — sets the amount of influence of the CV received
on the MOD pin.
CLAP knob — creates a clap sound by splitting the attack of the sound.
MIX
knob — determines the balance between pink and spectral noise.
BPF FR (band-pass filter frequency) knob — determines the cutoff
frequency of the band-pass filter.
MOD
(near the BPF FR knob) pin is the CV input that controls the BPF cutoff frequency.
BPF Q (band-pass filter resonance) knob — determines the level of self-oscillation of
the filter.
EXT
(external) pin is the input for processing an external signal through the SD synthesis
circuit. Located before the band-pass filter.
OUT pin is the output of the SD synthesis module. Located before the VOLUME knob.
VOL
(volume) knob — SD volume control.
FX knob — adjusts send level of the SD signal to the effects processor. Takes the signal
before the VOL knob (pre-fader). This way you can send a signal to the effects processor
while the SD volume in the main mix is low or zero.
Use a band-pass filter on the verge of self-oscillation (set by the BPF Q knob) to cre-
ate the characteristic resonance of the snare drum body.
