A LED indicator shows the amount of filter envelope sent to filter. The LED’s
brightness depends both on the envelope signal amplitude and on the
Velocity
signal sent by the keyboard (when the Velocity function has been enabled over
USB
by the
MiniBrute Connection
software; see the Software section of this
manual).
4.2.3 The amplifier
The amplifier controls the sound’s amplitude dynamics, as determined by the
Amplifier Envelope
and
LFO
parameters.
4.2.3.1 Amplifier Envelope
In normal mode, the Amplifier envelope is triggered by the
keyboard GATE signal. It can also be triggered by other
GATE sources such as the
Arpeggiator
clock [4.2.7] or the
rear panel’s external GATE IN jack [4.3.6]. Note that
depending on the position of the
GATE
switch located on
the rear panel [4.3.4] the amplifier envelope is under the
control of either the keyboard GATE signal, the automatic
GATE from the external
Audio input
, or the hold position of the
GATE
switch.
The
Attack
slider sets the duration of the envelope’s first stage. Depending on the
filter section’s
ENV Speed
switch [4.2.2.6] the Attack time ranges from 1ms to 1s or
from 10ms to 10s.
The
Decay
slider sets the duration of the envelope’s second stage. Depending on
the filter section’s ENV Speed switch [4.2.2.6] the Decay time ranges from 1ms to 1s
or from 10ms to 10s.
The
Sustain
slider sets the level of the envelope’s sustain stage.
The
Release
slider sets the duration of the envelope’s final stage. Depending on
the filter section’s ENV Speed switch [4.2.2.6] the Release time ranges from 1ms to
1s or from 10ms to 10s.
A LED indicator show the envelope amount sent to the amplifier. The LED’s
brightness depends on the envelope signal’s amplitude.
4.2.4 Controls
4.2.4.1 MOD Wheel
The
MOD Wheel
switch controls the
Modulation
wheel assignment
[4.2.8.2]. Depending on the position of this switch the Mod wheel
controls either the filter cutoff frequency (
Cutoff
position), the vibrato
amount sent to the oscillator (
Vibrato
position), or the amount (
LFO Amt
)
of the current LFO signal to the various targets (
