LFO, Low Frequency Oscillator
The LFO provides a sub-audio signal for modulation purposes. It is used to achieve periodic modulations
like sweeps, vibrato effects or arpeggios.
RATE determines the frequency of the LFO and is indicated by the LED
WAVEFORM SELECTOR provides seven different waveforms.
The patch-section offers some more LFO functions:
The GATE SOURCE SELECTOR switch enables the LFO to start at a zero-crossing and thus to sync
the LFO to MIDI/GATE 1, MIDI/GATE 2 or to an external signal patched to the EXT GATE socket.
Additional sockets allow the modulation of RATE and LEVEL and provide the LFO-OUTPUT.
Some interesting results can be achieved when the LFO OUTPUT is fed back to the EXT GATE input socket.
