LFO contour
By LFO Contour you can now bend 
or ”morph” (almost) all the LFO 
waveforms. A brief survey of the 
LFO Contour options for the differ-
ent LFO modes follows:

Sine Contour morphs from sine to 
a triangle wave (Contour to the 
left) or to a square wave (Contour 
to the right).
Triangle Contour morphs from a 
triangle to a declining (Contour to 
the left)  or ascending sawtooth 
(Contour to the right).
Sawtooth Contour morphs from a 
linear declining sawtooth or decay 
to any exponentially declining 
decay(Contour to the left) or to a 
square (Contour to the right).
Square Contour modulates the 
pulse width of the square wave.
Waves Contour ”zooms” into the 
wave, thereby shortening the 
wave’s loop length (Contour to the 
right).
Clock
When you set it to OFF, the LFO 
oscillates in the normal manner, 
independently of the global Mas-
ter Clock (CLOCK TEMPO). When 
you enter a note value here, the 
LFO rate is synced up to the global 
master clock. The length of the 
waveshape’s cycle will then corre-
spond to the note value that you 
have entered. You can also set the 
rate via CLOCK TEMPO (refer to the 
appropriate section) or synchro-
nize it to external MIDI clock.
