& Reset In
LFO synchronisation is possible, by sending a trigger
signal (eg. a gate) to the reset input. Every time a
trigger voltage is sensed (for instance when a key is
pressed), the LFO’s waveform resets, and starts from
its zero point (see Fig. 2).
Without synchronisation, the LFO is free running, so
that wherever the waveform is when the trigger arri-
ves, that’s where it starts from (see Fig. 1).
P Particularly with lower frequency modulati-
ons, you can use the reset / synchronisation
option to make sure that the LFO starts from
zero whenever a key is pressed (Keyboard
Gate Ö Reset LFO).
If you don’t want this effect, then leave the
reset input unconnected, for a random LFO
waveform response.
