LFO waveshapes

The OB-6 has a sixth “hidden” LFO waveshape that you can use as a modula-

tion source — noise. To access this, choose random then turn frequency all the way

clockwise. This generates a white noise waveform.

The LFO can be free-running or synced to the arpeggiator, sequencer, or

MIDI clock for tempo-synced effects such as lter sweeps, tremolo, and so on.

Frequency: Sets the frequency of the LFO waveshape routed to the

destination from a slow .022Hz to a fast 500Hz. See also “LFO Sync”

below.

LFO Sync: When on, the LFO synchronizes with the arpeggiator,

sequencer, or MIDI clock. By default, the LFO wave cycle is reset when

you press a key (but is not reset if you press a key while other notes are

held).

Shape: Sine, Sawtooth, Reverse Sawtooth, Square, Random—The

wave shape of the LFO. A sixth waveshape, noise, can be generated by

selecting random and turning the frequency knob all the way to the right.

Initial Amount: Sets the amount of LFO modulation routed to the

selected destinations. Setting an amount here applies the selected modu-

lation continuously. If you set this parameter to zero but still select a

modulation destination, modulation is only applied when you use the

Mod Wheel.

VCO 1: Selects the frequency of Oscillator 1 as a modulation destina-

tion. Use a sine wave as a source to create vibrato. Use a square wave to

create trills.

VCO 2: Selects the frequency of Oscillator 2 as a modulation destina-

tion. Use a sine wave as a source to create vibrato. Use a square wave to

create trills.
