Version 2 LFOs


LFOs (Low Frequency Oscillators) are very important as sources of modulation in Modular patches. For more information on LFO's see the 'What Is it?' page, LFO section.


One difference between the version 2 LFOs and the version 1 LFOs is that there are Monophonic and Polyphonic versions of the LFOs. Or rather, each LFO can be loaded as Monophonic or Polyphonic, by right-clicking on the module and selecting the 'Switch to Single/Polyphonic mode'. When in Polyphonic mode the module will be blue, and green when it is in Single mode. In Polyphonic mode, the LFO will be implemented once per voice in the patch, which means that each voice will have it's own independent LFO, whereas in Single mode, the LFO is only implemented once and will modulate each voice identically.


Sine LFO (1.1%)

Simple Sine Wave LFO with rate (frequency) control.

Square LFO (0.9%)

Simple Square Wave LFO with adjustable rate.

Triangle LFO (0.9%)

Simple Triangle Wave LFO with adjustable rate.

Saw UP LFO (0.5%)

Ascending Saw Wave LFO with adjustable rate. 

Saw Down LFO (0.5%)

Descending Saw Wave LFO with adjustable rate.

Pulse LFO (6.5%)

A Pulse Wave is similar to a Square Wave except that the width of the Pulse is non-symmetrical. See the more detailed explanation on the Version 1 Oscillators page. The Rate can be set using the Rate control, or set externally (using Midi Clock, for example) and can be modulated by either of the Rmod inputs controls.

The Pulse Width can be set using the PWidth control and modulated using the PwmA input. 

The LFO can be set to be free-running or to retrigger on each new gate signal. The Keyfollow control allows you to determine the amount by which the rate of the LFO will vary according to the keyboard position.

Multi LFO A (4.9%)

Multi LFO with options of Sine, Square, Saw UP, Saw Down, Triangle and Random waveforms. The Delay, Fade In & Fade Out controls determine how long it takes for the LFO to start after triggering, and whether, once started, it will come in at full strength immediately or fade in and out. The Init Phase control determines where in the cycle the LFO will start. The rate of the LFO can be set internally or externally, and can be modified by the RMod inputs, and also be keyboard position using the KeyFollow input.

Multi LFO B (2.5%)

Same as above, but without the modulation options.

Mod Wheel Triangle LFO (%)1.4

A Triangle LFO with hard-coded intensity modulation, defaulting to ContinuousController#1. Use this to emulate the ModWheel functionality of your keyboard (which will also probably use cc#1).

Can be free-running or retriggered, and the Initial Phase of the LFO can be set. Controls for Delay and Fade In times as well.

Random Signal Generator (4.3%)

A well specified random signal generator. It can output three types of Random signal - Sine, Triangle or Step ('Sample & Hold'). The Rate and Level can be set by the user, but if an external signal is used the Rate control will no longer have any effect.

Sample & Hold (1.4%)

Sample & Hold modules are often used to generate random signals. They take a peridoic 'snapshot' of the Source signal's amplitude and output this value until the next triggering event occurs. The trigger for the next sample to be taken can be a Gate event, an LFO, etc. If using an Audio trigger (the Trig input) then the Threshold can be set for the Sample to be taken. If the Input signal is Noise then the output will be random.
