Knob: FILTER DECAY  It controls the 
decay time of the envelope fol-
lower. With this parameter, you 
can determine how swiftly the 
envelope follower will respond to a 
decrease in signal level. Higher val-
ues let the Follower linger.

Knob: FILTER SUSTAIN It controls 
the input level of the envelope fol-
lower directly. The nominal value is 
the center position (64).

Pulse width modulation is a very 
effective method for producing 
beat oscillations without having to 
resort to several detuned oscilla-
tors.

Dial OSC BALANCE to the far left so 
that only OSC1 is audible, then 
select the waveform Pulse for this 
oscillator (OSC1 Shape to the right). 
Slowly turn the Pulse Width (PW) 
knob back and forth. As you 
change its pulse width, you’ll hear 
movement in the sound itself. 
When its pulse width remains 
fixed, the sound will remain static. 
This to-and-fro pulse width modu-
lation can be automated by means 
of an LFO. Select PWM for LFO1 
Amount and set a relatively high 
modulation amount. You can vary 
the intensity of the modulation via 
LFO Rate.

Now when you play different 
sounds, you’ll will find that the 
intensity of the modulation is con-
siderably greater with low-fre-
