3. CREATE A PATCH
This chapter walks through the basics of sound design on the PolyBrute, starting with an
initialized patch, shaping it, and finally saving it. Advanced users can jump to areas of
interest by following the links in each section.
3.1. Subtractive synthesis
PolyBrute is an analog subtractive synthesizer. This method of synthesis starts by
generating raw waveforms, and then uses filters to remove (subtract) unwanted harmonics
to achieve the desired sound.
However, PolyBrute also has the Metalizer, Sync and FM functions in the oscillator section
which can add harmonics to the basic oscillator sound. The results then can be sculpted
further with the filters.
The basic signal flow is simple, and generally follows this order:
•
VCO (voltage-controlled oscillators) [p.22]
generate the waveforms and control
the pitch frequency
•
VCF (voltage-controlled filters) [p.28]
shape the harmonic content
• Envelopes, LFOs, and other sources are used to alter (modulate) parameters.
Modulators can even control other modulators.
Speaking of which, one of the main features of the PolyBrute is its Matrix. This is an internal
patchbay that can route any modulation source to one or more destinations. Some sources
are physical, such as the Morphée controller; others are internal, such as an LFO, and can
run freely or synchronize to the master clock (internal or external). The impact on the sound
can be as subtle or extreme as you like.
Finally the signal passes through the amplifier section, takes a detour into the effects section
(if desired), and then the output level is set by the Master Volume control.
This manual covers all of those features in depth. For now we'll start by building a basic
patch.
