Filters and Envelopes
Now its time to head for the Filter Section. The filters allow you to shape the sound
of the oscillators by removing sections of the frequency spectrum.
13. Left Click the Dual button.
14. Left Click the Link button.
Now both
filters are linked. Any changes made to one filter
will affect the other in the same way (with the exception of the Pan Sliders,
which work opposite to one another).
15. Left Click the Arrow next to the Type Field
and select 12dB/Oct LPF.
Now both
filters are set to low pass 12. Low pass filters are used
for cutting the highs.
With the
Cutoff Slider, you determine how much frequency you will allow through the
filter.
16. Increase
Cutoff to 18378.47Hz.
The Resonance
Slider controls the amount of resonance applied to the filter. Adding resonance
increases intensity in a synth tone.
17.
Increase Filter Resonance to 5.15dB.
Now to move to the Envelope Section. Envelopes are time-based parameters that
affect the sound of your synth.
Looking at
the Envelope Selector, you can see the A Tab is selected.
This means all changes made will affect the Amp Envelope. The Amp Envelope is most
important because it affects how your synths volume changes over time.
The Att Slider controls attack time. Attack time is the time
from the moment a note on message is received to the moment the envelope
generator reaches a value of 1. In simple terms, it is
the note fade-in time.
18. Set Amp Envelope Attack Time to a value of 0.01s.
Now the
attack stage will last 0.01 of a second.
The Dec
Slider controls decay time. Decay time is the time it takes the envelope to move
from the slope level (coming after the attack stage and set with the SLL
Slider) to the sustain level (set with the Sus
Slider).
19. Set Amp Envelope Decay Time to 10.00s.
As stated,
the Sus Slider controls sustain level. Sustain level
is the volume that a note will rest at once the decay period is over. Put
simply, this setting is how loud a held note will remain. Higher sustain levels
result in more powerful sounding synths.
20. Set Amp Envelope Sustain Level to 100.00%.
The Rel Slider controls release time. Release time is the time
it takes the envelope to drop to zero when a note off message is received. In other words, this slider controls the length
of note fade out.
21. Reduce
Amp Envelope Release Time to 0.01s.
