An LFO tool is a very easy and powerful tool to add sidechain compression and tremolo-style effects to your track.

Artists like Flume and Floating Points are great examples of this production technique. LFO tool is one of the best filtering tools money can buy to achieve this effect.

However, if you’re looking for a cheaper or free alternative, read on to find some of our top picks that give Xfer a run for its money.

Below we’ve listed 5 of the best LFO Tool alternatives you can add to your VST library. We’ve highlighted some pros, some cons, and our experience with the tools to help you decide which will be best for your production.

1. Midishaper by Cableguys


Powered by Curve's unique modulations engine, MidiShaper brings Curve's flexible yet powerful LFOs and envelopes to all your favorite synthesizers and effects.

Why We Love It:
  • Great control over LFO curve design
  • Endless design possibilities
  • Powerful

Midishaper is THE alternative option to the Xfer LFO Tool. Using the modulation matrix, you can control any parameter or effect.

Which can control up to 6 selected external parameters at one time.

Midishaper also allows you to create ten custom waveforms that you can use to customize your modulation.

In addition, you have a combination of 4 waveforms affecting the audio. A great tool for producers and sound designers alike.


  • 4 LFOs generators
  • 4 envelope generators
  • 10 user-custom waveshapes
  • Modulation matrix
  • External MIDI control


Midishaper is a close second to LFO Tool and is certainly the best alternate option.

Midishaper may seem intimidating at first for beginner and intermediate producers. Especially when it comes to the in-depth modulation matrix and routing.

However, given the chance, this is an incredibly versatile tool that adds a lot more depth to your music production.

Additionally, the UI is designed to help you learn the software providing helpful information as you hover over each section of the UI.

With the ability to add simple sidechain effects to complex sound design modulation, this is a great option for $29 (USD).

One downside of the VST is the routing, as it may be problematic within some DAWs like Apple’s Logix Pro X.

Luckily, Cableguys offers a free demo allowing you to try and see if this plugin is for you.



STFU is a super quick-to-use sidechainer that can be automatically synced to host BPM or triggered by MIDI notes and it's always sample-accurate.

Why We Love It:
  • MIDI or audio-triggered
  • Quick and easy
  • Free
View Price On ZEEK

STFU is a very simple but effective volume shaper tool. You can have as few or as many points on the graph as you want to design your wave shape.

The VST can use either audio or MIDI as a trigger, you are not limited as to what you can use this plugin on.


  • 2 envelopes to blend between 


I often use this plugin as it’s very fast and extremely intuitive. When I’m in the early stages of a track, this is an excellent tool to produce a good idea of what I want it to sound like.

It’s also very friendly UI, although it is basic and lacks some key features that I would want, like a wet/dry mix.

You can achieve this by using the second envelope with no filter, but this removes the point of being able to blend them both.

As a free volume shaper VST, it’s great, but that’s all it is, as you can’t control any other parameters.

Compared to LFO Tool and Midishaper, it lacks the features to make it a top contender.

3. Flux Mini 2 by Caelum Audio

Flux Mini 2

Flux Mini 2 is an audio effect that adds life, character, and dynamism to your tracks.

Why We Love It:
  • User-friendly UI
  • Very accurate waveshaper
  • Easy to use
View Price On PluginBoutique

The little brother to Flux Pro, Flux Mini 2 has all of the main features you would expect from this tool.

The graph and waveshaper are very accurate and allow for pinpoint sidechaining. Included are 20 presets, providing ample opportunity to experiment with the plugin.

With a very polished UI, this VST is suitable for professional and amateur producers.


  • Low-pass, high-pass, and band-pass filter options
  • Can control resonance, cutoff amp, and mix with envelope


Flux Mini 2 has all the additional control and features I was looking for in ZEEKS STFU.

More features like its filter cutoff, resonance, and a wet/dry mix make this a far better sound design tool.

With this VST, you also have far more control over designing the shape of the envelope.

Which, in addition, can control resonance, cutoff, amp, and mix. This is certainly the best LFO tool free alternative on our list.

One thing I would say is missing from this plugin is an additional few envelopes to provide more design possibilities.

4. TAL-FILTER 2 by TAL Software

TAL-Filter 2

TAL-Filter-2 is a host-synced filter module with different filter types, panorama, and volume modulation possibilities.

Why We Love It:
  • Plenty of modulation options
  • Depths and stereo control are a great addition
  • Easy to use graphical editor
View Price On Amazon

This filter has a plethora of modulations for the user to design their waveform.

Accompanied by the imaging, stereo and depth effects allow for creating both tremolo and gated style effects. 


  • Low-pass, high-pass, band-pass, pan, and volume modulation modes
  • Depth, resonance, and stereo control


This is a great little VST and is fun to use on tracks, especially with the different modulation modes and effects.

I’ve found the best results using the panning modulation, this can create some cool movement in a track and sounds great on drums.

However, the TAL-FILTER seems to lack clarity and accuracy when compared to Midishaper and Flux mini 2.

5. MTremolo by MeldaProductions


MTremolo provides a definitive tremolo sound with an adjustable shape, including editable waveforms and harmonics. 

Why We Love It:
  • Great for experimentation with random feature
  • Brilliant tremolo effect
View Price On Melda Production

MTremolo is slightly different from the rest on our list as it has been designed as a volume shaper with a sequencer.

You are also able to split the effect into 2 bands, and it includes a visual UI to help pinpoint the frequencies you want to isolate.


  • Sequencer-style waveshaper
  • Smart randomization tool


I like this VST, especially the control and UI used for controlling each frequency band.

The step sequencer is also a great addition to this plugin and is VERY similar to the step sequencer in Native Instruments Massive, which isn’t a bad thing.

However, unlike our other picks, drawing the shape you’re looking for in the graph is far harder.

So if you’re looking for a more accurate tool, one of our other picks will be best for you.
