The rectified sine wave setting will behave similarly to the regular sine wave but with the time 
spent on the starting point will be halved. 
 
The saw-tooth settings will slide upwards from the starting point to the stopping point effect types 
and then rapidly return to the starting point. 
 
The triangle step settings will sequentially switch up and down through the effect types between 
the selected starting point and stopping point effects. 
 
The step saw settings will all climb upwards from the starting point to the stopping point effect, 
switching between effect types and then rapidly returning to the starting point. 
 
The random step setting will randomly switch between effect types between the selected starting 
point and stopping point effects. 
 
8. LFO TO EFFECT SELECTOR AND EXPRESSION PEDAL TO LFO SPEED 
 
This setting is identical to the previous setting (LFO to Effect Selector) only in this mode the 
expression pedal takes over control of the Speed knob. 
 
9. LFO TO FREQUENCY 
 
This setting uses input from the LFO signal of the Poly-Mod Pro to control the parameters of the 
Frequency knob. The Speed knob controls the LFO rate and the ‘XD’ parameter controls the 
depth of the LFO wave shape. When the ‘XD’ parameter is set below the neutral ‘0’ position, the 
LFO wave shapes will reverse. The differences will not be audible in the symmetrical LFO 
shapes such as the sine wave, rectified sine, square, and step triangle settings. While in this 
setting, each of the Poly-Mod Pro’s primary modulation sources (Envelope, LFO, or Hot Hand) 
are available for use on the selected filter effect type. 
 
To align the full range of the Frequency knob with the LFO, set the Frequency knob to 12 o’clock 
and the ‘XD’ parameter to half of its positive maximum (+6) or half of its negative maximum (-6). 
 
If the Frequency knob or ‘XD’ parameters are set such as that the value exceeds the range of the 
Frequency knob, the output will hit and remain at the maximum positive or negative position until 
the LFO returns to within range. 
 
10. LFO TO FREQUENCY AND EXPRESSION PEDAL TO LFO SPEED 
 
This setting is identical to the previous setting (LFO to Frequency and Expression Pedal to LFO 
Speed) only in this mode the expression pedal takes over control of the Speed knob. 
 
11. LFO TO MODULATION AND EXPRESSION PEDAL TO LFO SPEED 
 
This setting is primarily intended for the combination of LFO modulation with one of the other 
primary modulation sources of the Poly-Mod Pro (Envelope or Hot Hand). The primary 
modulation sources use the top panel depth and speed controls while the LFO uses the ‘XD’ 
parameter and an expression pedal for depth and speed. 
 
12. LFO2 TO MODULATION AND EXPRESSION PEDAL TO LFO2 SPEED 
 
This setting allows for the combination of an LFO with all of the Poly-Mod Pro’s primary 
modulation sources (Envelope, LFO or Hot Hand). The wave shape of LFO2 is restricted to a 
triangular waveform while the primary LFO is adjustable through the ‘LS’ parameter. The primary 
modulation sources use the top panel depth and speed controls while the LFO2 uses the ‘XD’ 
parameter and an expression pedal for depth and speed.
