Amp
). With the third option (
LFO Amt
), all the LFO modulation signals are controlled
by the Modulation Wheel so when it’s at its minimum position (
Min
) the targets
receive no LFO signal; when the switch is set on this position, make sure the
Modulation Wheel is fully engaged to maximum.
4.2.4.2 Aftertouch
The
Aftertouch
switch controls the aftertouch signal assignment;
aftertouch is very useful to trigger modulation events while playing
without using extra knobs or sliders, thus increasing expressiveness. The
Aftertouch
switch has three positions: it can be routed the filter cutoff
frequency (
Cutoff
), used to trigger
Vibrato
[4.2.5], or be disabled (
Off
).
4.2.4.3 Bend Range
The
Bend Range
knob controls the range of the
Pitch
wheel [4.2.8.2].
With this knob fully counter-clockwise, the Pitch wheel ranges from -1/2
tone (lowest position) up to +1/2 tone. With this knob fully clockwise, the
Pitch wheel ranges from -1 octave (lowest position) up to +1 octave.
4.2.4.4 Glide
The
Glide
knob sets the amount of portamento (i.e., how long it takes
for the pitch to glide from one note to another when notes are played
on the keyboard or by the Arpeggiator). With this knob fully counter-
clockwise, there is no glide and the note pitch transitions instantly to the
next note. Turning this knob clockwise increases the portamento effect. At the
maximum setting, it takes approximately 4s to glide from the lowest
C
of the
MiniBrute keyboard to the highest
C
(two octaves above).
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 3 Hz to 30
