Version OS 2.07

The polarity is important because the LFO phase always restarts on a note 

trigger. That makes the LFO like an extra pitch envelope which gets 
triggered by the note.

This parameter controls the waveform:

<SuP>  Sawtooth up

<Sdo>  Sawtooth down
<Sin>   Sine wave rising

<Si->   Sine wave falling
<tri>   Triangle with rising ramp

<tr->   Triangle with falling ramp
<rCt>  Rectangular jump from minimum to maximum

<rC->  Rectangular jump from maximum to to minimum 
<PL1>  Pulse width 60% on / 40% off

<PL2>  Pulse width 70% on / 30% off
<PL3>  Pulse width 80% on / 20% off

<PL4>  Pulse width 88% on / 12% off
<PL5>  Pulse width 40% on / 60% off

<PL6>  Pulse width 30% on / 70% off
<PL7>  Pulse width 20% on / 80% off

<PL8>  Pulse width 12% on / 88% off

LFO 1 Speed

< 000-252 >

Turn Potentiometer 6 (2_1 Coupl, 

Speed

) to edit the speed of LFO 1. 

The value is shown in the display. LFO 1 always works on the pitch of the 
kick drum.

Speed controls the frequency of LFO modulation. Low value = slow, high 
value = fast. The phase of the LFO always restarts with a gate trigger.

5.1.3. 

LFO 1 Int

(ensity)

< 000-252 >

Turn Potentiometer 7 (Noise, 

Int

) to edit the intensity of LFO 1. The value is 

shown in the display. LFO 1 always works on the pitch of the kick drum.

LFO 1 Intensity controls the amount of modulation. Zero turns the 
modulation off.
