middle setting (12 o'clock), you’ll hear a wha-wha-like effect when tweaking the
Cutoff knob. At maximum resonance the FILTER starts auto-oscillating, which
superimposes a tonal pitch to the filtered sound. Also try out the different modes
(LP, BP, HP, Notch).
Let's tweak the FILTER Cutoff and Resonance
5.2 Sound modulations
Return again to our initialized, basic sound shown at the start of this chapter. Set
the CONTROLS section’s MOD Wheel switch to Vibrato. Now while playing the
keyboard, turn the modulation wheel. The vibrato modulates the oscillator at the
rate defined by the VIBRATO section’s Rate knob. Now toggle the switch to its
various settings; the upper position creates up-trills and the lower, down-trills.
Return the MOD Wheel to its minimum position and set the CONTROLS section’s
Aftertouch switch to Vibrato. Play notes on the keyboard; increasing your finger’s
pressure on a key increases the amount of vibrato modulation. Reducing the finger
pressure reduces the amount of vibrato modulation. Aftertouch can also be
assigned to the FILTER Cutoff.
As you’ve heard, the Vibrato modulation is very gentle and musical — which is
great, unless you want to produce weird space sound FX! For more pronounced
modulation effects we’ll use the LFO, which provides six different modulation
waveforms. These waveforms can modulate most of the other MiniBrute sections:
the PWM and Metalizer, oscillator pitch, filter cutoff and eventually, the sound’s
amplitude.
Let's have fun modulating the OSCILLATOR pitch. Set all sliders, pots, and switches
as shown in the initialized patch [5.1], then press a key and tweak the LFO section’s
Pitch knob. Try different Rate knob settings too. Test and try the various LFO
waveforms; for example select the fifth waveform (random steps), set the
CONTROLS section’s MOD Wheel switch to LFO Amt, then adjust the Pitch knob to
maximum (clockwise). Press a key and adjust the modulation amount with the
Modulation wheel.
The four modulation knobs let you adjust not only the modulation amounts, but
also their polarity (whether increasing modulation increases, or decreases, a
parameter value). This is particularly evident when modulating the Pitch with the
sawtooth modulation waveform. When turned toward the + mark, the pitch glides
up slowly to the highest pitch, then snaps back to the lowest pitch. When turned
toward the – mark, the pitch glides down to the lowest pitch, then snaps back to
the highest pitch.
