LFO Tricks & Tips:
The Random LFO wave is truly random and is different for each voice and layer.
The Pattern (Pat) waveforms will sound the same on different layers and voices.
When the PatchCord amount for an LFO is a negative value, the LFO shape will be inverted.
(A rising sawtooth turns into falling sawtooth.)
Sine + Noise is very useful for simulating trumpet and flute vibrato.
When routing Hemi-quaver to Pitch...
+38 = major scale
+76 = whole tone scale
odd amount = S+H sound.
Try combining the Pattern LFOs, or controlling the amount of one with another, or combining
them with the clock divisors.
Lag Processors 1 & 2
Lag processors can be inserted in a modulation patch to inhibit
rapid changes in the modulation source or cause it to lag behind
the input. The amount (rate) of lag is adjustable from 0 to 10. A
setting of 0 will cause the least amount of lag. 10 is the slowest lag.

Lag processors are used to slow down and smooth rapid changes in
control signals. In the example above, the instantaneous switch change
becomes a smooth transition.

Sample Loop Modulation
Although there is no initial control, the sample loop position can be modulated using a
Cord.
See "Modulation Destinations" on page 94.
the loop is modulated. This feature can be used to implement pulse width modulation,
and other wavetable scanning synthesis techniques.

(+38) + (+76) = diminished scale (two cords)

The Lag Processors can also be used as 2 additional
summing amps. Summing amps are used to add several
modulation sources together so the output can be controlled
by a single Cord Amount. The output of Lag0in and Lag1
modulation sources are equal to the sum of any cords
connected to the Lag in destinations. The summing node is
located before the lag processor as shown in the diagram.
