The rate at which the oscillator oscillates creates the pitch. The oscillators in a
synthesizer are no different than ones found on electrical test equipment, except
that they can be put under
VOLTAGE CONTROL
. A music synthesizer allows you to
change the pitch of the oscillator by using a voltage. In the case of MicroBrute, the
keyboard, LFO, Envelope or external voltage source can be voltage control sources
that affect the pitch.
Signal Modifiers
Signal modifiers (or wave-shapers) transform, shape or distort the oscillator’s basic
signal to change their harmonic content. The MicroBrute provides three signal
enhancers:
The Ultrasaw
builds two phase-shifted copies of the basic sawtooth signal.
These copies have independent and ever-evolving phase shifts with respect to each
other, and are eventually mixed with the sawtooth signal. This results in a lively, rich,
and thick ensemble effect. Figure 20. On the MicroBrute you can control the
Ultrasaw rate with the LFO, ENVELOPE or KEYBOARD CV OUT by patching it in the MOD
MATRIX.
