Xaoc Devices Batumi
The Xaoc Devices Batumi (link to check the price at Perfect Circuit) is a voltage-controlled quadruple digital LFO. It features four voltage-controlled LFOs giving you the possibility of using each oscillator independently or in one of the three available synchronized modes (quadrature, phase, and divide).
But what you can do with the oscillators doesn't end there; you can also choose from the sine, square, saw, triangle, ramp, and trapezoid waveform output available. Moreover, voltage control is available for each oscillator's frequency and can also be synced to an external source (via tap tempo).
Finally, taking up only 10HP, with a total frequency range spanning for 28 hours (in divide mode), and the possibility of performing easy firmware updates via USB, you have enough power to transform any production for the time to come.

Intellijel Dixie II+
The Intellijel Dixie II+ (link to check the price at Sweetwater) was designed by Intellijel to be the heart of your Eurorack modular system. Indeed, as an upgrade from the famous Dixie, this new iteration of the classic utilizes the same triangle core oscillator but adds versatility to its performance.
Among these upgrades are the PWM dedicated control, an octave switch to tune the module on the fly with musical results, and the exponential FM. In this vein, the multiple waveform outputs combined with the PWM, FM, and Sync inputs can help you cover as much sonic ground as you can possibly need to.
Speaking of possibilities, the fine-tuning knob available transforms into a coarse knob when you set the module to LFO mode. Moreover, you also have the possibility of selecting between exponential and linear mode when plugging into the FM1 attenuator (one of the dual FM inputs).
Alone or combined with the Rubicon 2, this unit takes up only 8HP of space and is powerful enough to propel your music talent forward. If you have a small space and need big sounds, you have to check the Dixie II+ out before buying. You can see it in action in this video and this video.

DivKid created the øchd because he needed something to break the monotony in his own performances. He found his setup took him to a repetitive sequence of sounds and wanted to add some organic drift and movement to it. Therefore, you can expect an injection of organic, analog sound to your productions from the bombastic DivKid øchd (link to check the price at Perfect Circuit).
To begin with, this module only takes up 4HP of space but delivers with 8 analog triangle LFOs organized according to their speed. The outputs go from the fastest on top to the slowest on the bottom. Furthermore, the LFOs are free-running, tuned by ear to be musical, but are deliberate, not synced. Thus, you can easily expect some drifting, musical phasing, and organic animation as part of the sound.
The øchd also offers CV control with a built-in CV input and attenuverter. This allows you to go even slower than the slowest audio rate (25 minutes). Finally, this module, designed in collaboration between Instruo and Ben “DivKid” Wilson, is one of the most powerful in the market for its size. If you need to solve your LFO needs in the smallest possible space, this is the perfect option for you.
Vermona Modular fourMulator
This is another company offering a digital quad-LFO module for the demanding Eurorack enthusiast (like the Xaoc Devices Batumi). That being said, the Vermona Modular fourMulator (link to check the price at Perfect Circuit) takes up 34HP and offers a wide array of controls to go deep and fine-tune your sound to the last bit.
To begin with, this unit offers more than just the typical modulations you could expect from any other Eurorack module. This is because each individual modulator can be synced to a master internal clock; therefore, you can create complex, rhythmical, layered modulation structures as well as individual movements.
To make this happen and offer a wide tonal palette, every LFO in the module offers six waveforms: triangle, square, sawtooth (ascending & descending), random curve (sample & hold), and sine. Furthermore, oscillating between 0.005 Hz and 100 Hz and being fast enough to alienate oscillators sonically as well as VCAs and filters, you can achieve all sorts of otherworldly sounds easily.
If you have the room and the budget to bring one of these super-capable, easy-to-use, great-sounding modules to your Eurorack system, you can broaden the sonic palette of your productions drastically.
The Doepfer A-145-4 (link to check the price at Sweetwater) takes the opposite approach than the Vermona fourMulator; it is a no-frills, simple quad LFO in a very convenient 4HP size to fit any Eurorack system. The company named it the bread-and-butter device to get the job done.
Speaking of which, this module features four simple LFOs (triangle and rectangle waveforms) with a dual-color LED indicating whether the output voltage is negative (yellow) or positive (red). Also, each LFO allows an individual frequency range choice.
This is an ideal module to pair with other LFOs and create a complex sonic landscape. In the same vein, its simplicity, rubber knobs, and minimalist layout (added to the super-small size) make it great for your live setup and for adding options in a studio rig.
If you are looking for a small module that is powerful enough to get the job done with a minimalist, no bells and whistles approach, checking this one out before buying is a must. You can see it in action in this video and this video together with the A110 VCO.

The Audiophile Circuit League QLFO (link to check the price at Sweetwater) is a superbly powerful module that can work as a rudimentary VCO but was designed to work as a diverse, rare modulator. Indeed, the unit's ability to simultaneously generate a sine wave and 3 phase-shifted copies makes it a unique-sounding addition to your Eurorack system. Moreover, each copy features an output of its own.
You can regulate the frequency of these three copies (90º cosine, 180º inverted sine, and 270º inverted cosine) with a single knob. This knob covers a wide territory going from ultra-slow modulation to absolutely high-pitched fast motion. Furthermore, to give you even more control over the modulation effect, the frequency can be controlled by voltage with an attenuverter-equipped input. But that's not all; another CV input also allows you to pitch the LFO by volt/octave, covering a range of 2 to 3 octaves.
Finally, this module is great for working in a series of modulators to create a complex, multi-layered sonic landscape of modulators modulating each other. Taking up only 8HP of space, it is a no-brainer to overlook this unit when searching for your next LFO. You can see it in action in this video and this video.
Malekko Heavy Industry Quad LFO
Putting so many sonic choices at your fingertips in only 12HP is quite something. Adding the 16 steps of automation makes the Malekko Heavy Industry Quad LFO (link to check the price at Perfect Circuit) a unique module.
To begin with, this unit features a shape slider that can move through saw, ramp, triangle, and sine waveforms. Each of these LFOs can be sent directly to the output, or you can use them to drive other modules and create complex sounds.
Once you've come up with some amazing sounds, you can use the unit's powerful 16-step automation sequencer on each channel. Moreover, you can also use the auto-save and expand preset features when you use this module alongside the Varigate units (4+ and 8+).
This way, you can record your performance in real-time and let the unit play it back whenever you need it. In other words, press the REC button, adjust the shape, phase, distort, level, and frequency sliders, and let the QLFO repeat your movements automatically as the unit plays the sequence back.
Erica Synths Black Dual EG/LFO
What Erica Synths did with this module is nothing short of an exploit. With the Erica Synths Black Dual EG/LFO (link to check the price at Perfect Circuit), they managed to put together two full-blown ADSR envelope generators and a unique-performing LFO in a single 10HP Eurorack module.
To begin with, you can adjust the ADSR generators individually or utilize them as two simultaneous AD/ASR envelope generators. Moreover, you can also double them and utilize them as LFOs. On top of that, you can draw your custom LFO shape that sounds like nobody else's.
Also, you get trigger and gate inputs, direct and inverter outputs, a long/short EG switch, full ADSR looping, and LFO key follow function. In other words, this is not only a unique-sounding module, but also a super-powerful unit with a broad tonal palette at hand.
Finally, the diode protection for reverse polarity and the protection in all inputs and outputs against undesired overvoltage round up an amazing combo put together by Erica Synths, and that can change the way you make music.

Behringer 140 Dual Envelope/LFO
Taking up a modest 16HP of space, the affordable Behringer 140 Dual Envelope/LFO (link to check the price at Sweetwater) module is a great solution for the Eurorack enthusiast on a budget. Indeed, the brand is worldwide famous for being the best affordable solution for musicians everywhere, and this module is no exception.
For starters, this module features two independent analog ADSR envelopes. Each features a gate input, a manual trigger button, and faders controlling decay, attack, release, and sustain. Moreover, you also get distinct outputs for regular or inverted signals.
The analog LFO offers 5 waveforms and gets a dedicated fader to adjust frequency and delay time. Speaking of frequencies, you can select what you need from three available ranges going from 0.05Hz to 30Hz. Finally, you can plug in the dedicated input and use CV triggers to control the module via voltage.

NANO Modules Quart
The NANO Modules Quart (link to check the price at Perfect Circuit) is a Eurorack module designed to deliver the sounds you need with none of the hassles of bigger, more complex modules. It is a 10HP quad AD envelope (Attack-Decay) and LFO. Using one mode or the other depends on whether the trigger inputs are connected or not.
The Quart features four independent functions. It works as a very capable AD envelope when the trigger input is connected. On the other hand, if the trigger is not connected, the function oscillates freely. Moreover, you can control the rise and fall time with a dedicated control per channel to have ultimate fine-tuning capabilities on the overall sound.
Also, the unit comes with three selectable time ranges per channel: slow, medium, and fast. These ranges go from 0.1ms to 80s. Finally, you also get a trigger and signal output per channel to route your audio to other modules or the output.
The NANO Modules Quart is a powerful solution in a reduced module that is easy to maneuver, especially in a live situation. If you want to check out what it can do, watch this video for a full review.
4ms Quad Pingable LFO
The QPLFO as a built module is now discontinued, but you can still purchase it as a DIY kit (link to check the price of a DIY kit at 4ms).
This highly-playable, clock-syncable 4-channel LFO with variable reset, skew, and tap tempo is one of the most powerful yet small (12HP) one-stop solutions for all modulation needs in Eurorack size.
To begin with, it can create an astonishing number of modulation sources, allowing you, as a creator and player, a level of freedom unheard of before. Moreover, each of the four channels available in this QPLFO is an independent LFO with the ability to create a plethora of wave shapes. This includes triangle, ramp-up, ramp-down, pluck, and all the conceivable in-between shapes as well.
In the same vein, each of the channels can also interact with the rest by modulating, triggering, and resetting. Thus, you can create high-complexity layered sonic scapes with morphing outputs.
Versatility is the name of the game for this new creation by 4ms. If it fits in your budget and you've been after a super-powerful LFO, you should check this unit out. To see it in action, you can watch this video and this video.
