6.1.5. Modulators
Modulators provide signals that are designed specifically to control the behavior of
oscillators, filters and amplifiers. Unlike audio oscillators, modulators are low-frequency
signals. For example, when you sing with vibrato, you are “modulating” your voice with a
low-frequency change in pitch, typically around 5Hz or so. The tremolo circuit in a guitar
amplifier modulates the amplifier’s level.
Modulators are useful to create dynamic pitch changes (like “wobulation” or creating chirps),
timbre sweeps, and level variations. The main modulators are the LFO (low frequency
oscillator) and envelope generator, but they can also be provided by external sources that
generate
control voltage (CV) signals that provide modulation, and gate signals that turn
modulators or notes on and off.
6.1.5.1. Low-Frequency Oscillators (LFOs)
An LFO is low frequency oscillator that can produce various waveforms at sub-audio
frequencies (0.05Hz up to 100Hz). In MiniBrute 2S the waveform options are sine, triangle,
sawtooth, square, random steps, and random waves. These waves’ amount and polarity
(i.e., whether they go positive or negative) can be controlled before being fed to the target
devices.
A signal can be modified by random steps or smoothed random steps
