Another important sound modulation source is the
FILTER ENVELOPE.
This provides
dynamic control over either the
FILTER
Cutoff
,
OSCILLATOR
Pulse Width,
or the
Metalizer
harshness. The
FILTER ENVELOPE
amount and polarity are controlled by
the
Env Amt
knobs, which are very useful when you want to create lively sounds.
5.3 External sound processing
Plug your external audio source in the
Audio In
1/8'' jack [4.3.5] on the MiniBrute’s
rear panel. Your audio source must provide line level signals, so with electric guitar
you’ll need to patch a preamp or other processor (e.g., compressor, distortion,
multieffects) between the guitar and the
Audio In
. Adjust the
OSCILLATOR MIXER
’s
Audio In
slider to the desired level.
When using an external audio input, select a
GATE Source
setting that corresponds
to how you want to process the external source.
•
To trigger the envelopes with the keyboard, set the
GATE Source
switch on
the MiniBrute’s rear panel to the
KBD
position.
•
To hear the external source continuously and process it, select the
Hold
position.
•
To trigger the envelopes when the external signal level exceeds a fixed
threshold, select the
Audio In
position (you can change the threshold level
using the MiniBrute's software; see chapter 4.4.
The following setting produces an
auto-wha
effect combined with tremolo. The
Modulation
wheel controls the amount of tremolo (make sure that the
CONTROLS
section’s
MOD Wheel
switch is set to
LFO Amt
).
