How to choose the best LFO modules
Waveform Variety
Beyond the standard sine and triangle, look for modules with random, sample-and-hold, or stepped waveforms. These unlock a lot more creative possibilities without needing extra modules.
Rate Range
A truly useful LFO needs to go from glacial slow to frantic fast. A narrow rate range will quickly become limiting, especially for subtle modulation or complex sequences.
Shape Control
Simple sine/triangle/square is fine, but having some control over the shape - pulse width, asymmetry - lets you dial in more interesting modulation textures. Think subtle phasing or a more aggressive tremolo.
Linear/Exponential Response
This dictates how the LFO's voltage translates to changes in your target parameter. Linear is often more predictable, while exponential is more sensitive and can create more dramatic effects. Ideally, having a switch for both is best.
CV Outputs
Some LFOs offer multiple outputs, which is huge for complex modulation. Being able to send different waveforms or phases to multiple destinations opens up a whole new level of sound design.
Buying guide
Alright, so you're diving into modular and need an LFO, but you're not trying to drop a grand on it. Totally get it. A decent LFO is the backbone of so much movement - tremolo, vibrato, sequenced patterns, crazy modulation - and you don't need to break the bank to get useful ones. This list is about getting the most wiggle for your dollar, modules that'll actually add something to your sound without leaving you feeling ripped off.
At this price point, you're making trade-offs. Don't expect pristine build quality or a huge number of features. Often, you'll find slightly more noise than you'd like, or a limited rate range.
Prioritize waveform variety and a decent rate range - those are the things you'll actually use. Paying a little more for a module with true bipolar output can also be worthwhile, as it gives you more flexibility in modulation depth.

Questions
What's the difference between a bipolar and unipolar LFO?
Bipolar LFOs output both positive and negative voltages, allowing you to modulate parameters in both directions (e.g., pitch down and pitch up). Unipolar only outputs positive voltages, limiting your modulation possibilities. Bipolar is generally more versatile.
Can I use these LFOs for tempo-synced modulation?
Most can, but you'll need a clock source and a way to divide it down. Some modules have built-in clock dividers, which is a major convenience. Otherwise, you'll need to patch a clock signal into the rate input and use attenuators/dividers to get the desired speed.
Are these modules true random LFOs?
Not always. Many 'random' LFOs are actually pseudo-random, meaning they generate a sequence that appears random but is ultimately predictable. For truly unpredictable modulation, you'd need a dedicated noise generator or a more complex module.
What if I only want to use it for vibrato?
Even for simple vibrato, a versatile LFO is still valuable. You can use different waveforms for subtle or dramatic vibrato effects, or use the shape controls to create a more organic, less mechanical feel.
Are these modules noisy?
It's a common trade-off. Cheaper components can introduce more noise. While it's rarely terrible, it's something to be aware of, especially if you're recording quiet signals. Experiment with filtering or noise gates if it's a problem.
