This module provides 4 LFOs in a small package, with an array of unique features. It is inspired by the popular Eurorack digital LFO Batumi.

There are 4 sliders to control the frequency of each LFO in free mode. Slider 1 will always control the frequency of the first oscillator, but when the mode is changed via the toggles at the bottom right, sliders 2 to 4 will change function accordingly. In phase mode they will control the phase displacement from oscillator 1, and all the oscillators will have the same frequency. In quadrature mode, they will become inactive and the frequency of all oscillators will also be controlled by slider 1. In divide mode, sliders 2 to 4 control the amount by which the frequency of the respective oscillator will be divided compared to oscillator 1. All these information is automatically updated in the tooltips for the respective sliders.

The mode switches are global, but all the other controllers on the right strip are specific to each oscillator. To affect the desired oscillator you can select the respective toggle below the sliders (which will turn red for the selected one), or simply move one of the 4 sliders, as these are in a sense touch-sensitive. Selecting an oscillator will result in the respective controls on the right updating to display the status of that oscillator, as well as the label at the top displaying the corresponding number, and changes to the controls on the right strip will also affect just that oscillator. These controls are the output level, the CV attenuverter value, the range, the polarity, and the waveform for the triangle output. There is also a switch to reset the phase of the individual oscillators, but keep in mind that this will affect the phase and quadrature relationships when used in those modes.

The reset inputs can be used to sync the signals of the respective oscillators (in the next update it will be possible to use these inputs and the reset buttons to set the frequency of the oscillators by tapping the desired rate).

The sine output will always output sinusoidal waves.

The Triangle output will output either triangle, ramp or sawtooth waveforms, depending on the settings of the toggles on the right.

The output at the bottom of each channel can be toggled to output either a square waveform or triggered S&H random values, using the toggles just below them.

This module is great for adding very flexible modulation sources to your patches while taking up little space.
