4.2.5 Vibrato
The Vibrato is a specialized low frequency oscillator dedicated to
oscillator pitch modulation. It’s completely independent from other
modulation sources, and its modulation depth and triggering are
controlled by the Modulation wheel [4.2.4.1] and the Aftertouch switch
[4.2.4.2] respectively. It provides different modulation waveforms,
selectable with a three-position switch:
• a positive square wave useful to create a trill-up effect (the pitch jumps
alternatively between the keyboard pitch up to a higher pitch depending
on the Modulation wheel setting);
• a sine wave for the classical vibrato effect;
• a negative square wave for trill-down effect.
The Rate knob controls the Vibrato’s modulation rate, and ranges from 3Hz to
30Hz.
4.2.6 LFO
The LFO is a low frequency oscillator. It is the primary
modulation source for the MiniBrute’s other sections.
4.2.6.1 Wave
The LFO offers several modulation waveforms, selected by the Wave
knob: sine, triangle, sawtooth, square, random stepped (also referred to
as Sample & Hold), and random gliding.
4.2.6.2 Rate
The Rate knob set the LFO oscillation rate, and ranges from very slow
rates (0.1Hz) up to quite fast rates (100Hz). The red LED located above the
knob blinks in time with the rate. Note that the LFO rate may be
superseded by the Sequencer tempo clock if the Clock switch is set to
Seq (see below).
