3. In the envelopes section, set the Filter Envelope’s decay to 6.
4. In the envelopes section, set the Filter Envelope’s sustain to 2.
5. Repeatedly play a note as you turn the resonance knob to 6. Notice
how the sound changes as a band of frequencies near the cutoff is
amplied.
6. Rotate the lter’s cutoff knob again and you’ll hear a classic resonant
lter sweep. You’re going to use this to create your synth bass.
7. Set the lter cutoff to a value of 3.
8. Set the lter resonance to a value of 3. This is going to give the synth
bass its funky “zap.”
9. Play a note and listen to the sound. At this point you won’t hear much
because you’ve mostly closed the lter. You’ll need to open the lter
wider using the Filter Envelope (so you don’t have to turn the cutoff
knob by hand).
To adjust the lter envelope:
1. In the Envelopes section, turn the Filter Envelope’s envelope amount
knob to a value of 10.
2. Play a low note on the keyboard. Instant synth bass!
3. If you want, set the frequency of Oscillator A and Oscillator B an
octave lower using the frequency knob.
Notice how the sound has changed. The Filter Envelope is controlling
lter cutoff by the amount you set with the amount knob.
4. Continue experimenting with the Filter Envelope’s amount knob.
Notice how greater amount settings amplify the effect of the envelope
on the lter.
5. Repeatedly strike a note on the keyboard as you turn the Filter Enve-
lope’s decay knob clockwise and counterclockwise. Notice how it
changes the sound as the note decays faster or slower.
Be aware that the Filter Envelope and Amplier Envelope work in
conjunction, with the Filter Envelope controlling how the lter opens and
closes and the Amplier Envelope controlling the overall volume shape.
