Low Frequency Oscillators
LFOs are special-purpose oscillators that produce frequencies below the
range of human hearing. LFOs are typically used for periodic modula-
tion or changes in sound such as vibrato (periodic pitch modulation) and
tremolo (periodic volume modulation).
The Pro 2 provides four LFOs that produce a variety of waveshapes.
Although they’re classified as low-frequency modulation devices, they
can actually function at speeds that extend into the audible range for
extreme modulation effects. The LFOs can be free-running, reset by
keystrokes, or synced to the arpeggiator, sequencer, or MIDI clock.
Press any of the four LFO buttons to choose an LFO for editing.
To edit the same parameter on all 4 LFOs simultaneously, press and briefly
hold one of the LFO selector buttons and turn one of the dedicated knobs (

OLED display to individually edit the same parameter on each LFO. To exit this mode,
press any of the LFO selector buttons.
