LFO Tool

One section that you’ll always find on any virtual synthesizer and even on a few effect plugins is the LFO. Short for low-frequency oscillator, the LFO is a tool that many producers employ to modulate their sounds. Just like an oscillator, the device emits a sound frequency, which usually isn’t higher than 20 Hz (hence the name). While we can’t normally hear its frequency, the LFO’s waveform is often used to modulate other parameters from a synth.

If you want an easier way to modulate your soundand more control over this aspect, then you can always try a plugin called LFO Tool.

The plugin comes with an in-built filter which can be adjusted by the highly customizable LFO. The most exciting feature of the application is that you can edit the curve of the LFO by dragging nods with your mouse. You can also add and remove nods by double-clicking and create steep fluctuations. This will result in a powerful vibrato, an effect that is used throughout most genres of music.

But this where LFO Tool’s versatility begins. You can create up to 12 different curves and switch between them in order to add some variety to the track. There are also plenty of presets that you explore; some of them have been specifically designed to imitate sidechain compression, which makes LFO Tool an ideal plugin for shaping basslines.

I’ve already mentioned that LFOs are often used to modulate other parameters of a synth. LFO Tool is capable of emitting MIDI signals that can be used to control other virtual instruments. There’s no doubt that you need to gain a bit of experience as a music producer to unlock the plugin’s full potential, but once you do, you may understand how LFO Tool can make your life easier.
