Rate CV Input:

 The 

Rate CV Input

 is a bipolar control voltage input for 

the 

Rate

 parameter. 

• 

Control voltage is summed with the knob position and scaled and/
or inverted by the

 Rate Attenuverter

.

• 

Applying positive control voltage can force the frequency of each 
individual LFO to exceed the range accessible by the 

Rate

 knob.

• 

Applying negative control voltage can force each individual LFO to 
completely stall, similar to a track and hold circuit.

• 

Bipolar CV Input.

Rate Attenuverter:

 The

 Rate Attenuverter

 scales and/or inverts the 

signal present at the 

Rate CV Input

.

LFO Outputs:

 Eight bipolar triangle waveform LFOs are configured from 

fastest to slowest, arranged from top to bottom.
Output range: 10Vpp.
