Each timbre has two LFOs (low-frequency oscillator). The cyclic change produced by an LFO can modulate various aspects of the sound such as the pitch, tone, or volume.
1. Wave [Triangle, Saw Down, Saw Up, Square, Sample & Hold] (CC#89)
Selects the LFO waveform.
2. Mode [Tempo, Free, One Shot]
Specifies whether the LFO cycle is synchronized to the tempo or MIDI clock.
Tempo: The LFO cycle is synchronized to the tempo or MIDI clock. When Clock Source on the MIDI page in Global (MIDI clock settings) is set to “Internal”, the LFO synchronizes to the tempo that’s set by the Tempo parameter. When the value is set to “External MIDI/USB”, the LFO synchronizes to MIDI clocks received from an external MIDI device. When the parameter is set to “Auto”, the LFO synchronizes to MIDI clocks from an external MIDI device only if they are available.
Free: The LFO cycle is not synchronized to the tempo, and instead repeats at the rate set by Frequency.
One Shot: The LFO cycle is not synchronized to the tempo, and is instead output for one cycle only at the rate set by Frequency.
3. Frequency (Freq) [“Mode” Tempo: 1/1, 1/2, 1/3, 1/4, 1/6, 1/8, 1/12, 1/16, 1/24, 1/32 / “Mode” Free, OneShot: 0...127] (CC#90)
Sets the frequency of the LFO.
When Mode is set to “Tempo”: This sets the LFO cycle to a ratio of the tempo. The set value (note length) in relation to the tempo equals one LFO cycle. For instance, a setting of 1/4 makes one beat equal to one cycle.
When Mode is set to “Free” or “One Shot”: This sets the LFO frequency. Increasing this value results in a faster frequency.
4. Key Sync/Key Trigger [“Mode” Tempo, Free: Off, Timbre, Voice/“Mode” OneShot: Timbre, Voice]
Specifies whether the LFO phase is reset when a note-on occurs for that voice (meaning when you play a key).
“Key Sync” (when Mode is set to “Tempo” or “Free”)
Off: The LFO phase is not reset when a note-on occurs.
Timbre: The LFO phase is reset at the first note-on that occurs while no keys are pressed. The same phase is used for modulating all voices that are triggered by a note-on afterwards.
Voice: The LFO phase is reset at each note-on, and each voice that plays uses its own LFO phase.
“KeyTrigger” (when Mode is set to “OneShot”) [Timbre, Voice]
Timbre: see “Timbre” in Key Sync.
Voice: see “Voice” in Key Sync.
5. Smooth [0...127] (CC#91)
Smooths out the motion of the LFO.
1. Wave [Triangle, Saw Down, Saw Up, Square, Sample & Hold] (CC#102)
2. Mode [Tempo, Free, One Shot]
3. Frequency (Freq) [“Mode” Tempo: 1/1, 1/2, 1/3, 1/4, 1/6, 1/8, 1/12, 1/16, 1/24, 1/32 / Mode “Free”, “OneShot”: 0...127] (CC#76)
4. Key Sync/Key Trigger [“Mode” Tempo, Free: Off, Timbre, Voice/“Mode” OneShot: Timbre, Voice]
The Wave though Key Sync/Key Trigger parameters are the same as for LFO 1.
5. Delay [0...127] (CC#92)
Delays the time that it takes for the LFO to take effect once its phase has been reset. No delay is used with a setting of 0.
