4.5.5. Rate control for synced LFOs

When an LFO Sync button is active, moving the LFO Rate knob selects different time

divisions for the LFO. The display shows the value as the knob is turned.

4.6. Filters

Filters define subtractive synthesis: they remove harmonic content generated by the

oscillators. High levels of resonance can drive filters into self-oscillation, so they are potential

sound sources. When modulated their timbre varies over time, which adds motion to the

sound.

PolyBrute features two types of Voltage-Controlled Filters (VCFs): a 12 dB/octave Steiner

filter and a 24 dB/octave Ladder filter. Each has its own features which will be described

separately, but first let's take a look at what they have in common.
