How to choose the best LFO modules
Waveform Variety
A few basic shapes (sine, triangle, square, sawtooth) are essential, but the more unusual waveforms - sample-and-hold, random, stepped - open up a whole new world of textures. That stepped waveform is gold for sequencer-like patterns, and a good S&H can add unpredictable life.
Rate Range
You need slow, creeping modulation for subtle effects, but also the ability to get into the audible range for wild, rhythmic movement. A limited rate range can feel restrictive, especially when you're trying to create evolving textures.
Linearity/Easing
This controls how the LFO's rate changes over its cycle. Linear is predictable, but easing - especially ease-in and ease-out - can create more natural-sounding movement, like a slowly swelling filter sweep. It's the difference between robotic and organic.
Sync Options
Can it sync to your clock? Absolutely critical for keeping things tidy and rhythmic. Different sync modes (1/1, 1/4, etc.) give you different levels of control over how the LFO interacts with your sequencer or drum machine.
Output Level/Polarity
A weak output signal will get lost in the mix, while a strong one can overload your mixer. Polarity (positive/negative) is vital for creating subtractive modulation - bringing something down instead of up.
Buying guide
Alright, so you're diving into the modular world and realizing you need more than just a VCO and filter. LFOs - Low Frequency Oscillators - are the secret sauce for that movement, wobble, and organic feel that makes synths sing. They're not just for vibrato either; think tremolo, panning, crazy modulation, and everything in between. Picking the right one can seriously elevate your sound, but there's a surprising amount of variation out there.
Don't chase the most features; focus on the core functionality and how it inspires you. Cheaper LFOs often skimp on waveform accuracy or rate stability, leading to a wobbly, unpredictable sound. Paying a bit more for a module with a wider rate range, better waveform shapes, and solid sync options will save you headaches down the road - especially if you're gigging.
Ultimately, it's about finding something that inspires you to experiment.

Questions
What's the difference between an LFO and a VCO?
A VCO (Voltage Controlled Oscillator) generates audio frequencies - the notes you hear. An LFO generates low frequencies, too slow to hear directly, but used to modulate other parameters.
Can I use an LFO to control filter cutoff?
Absolutely! That's one of the most common uses. Experiment with different waveforms and rates to create everything from subtle filter sweeps to aggressive, rhythmic pulsing.
What's 'sample and hold' (S&H)?
S&H takes a voltage (like from an oscillator or noise source) and 'samples' it at regular intervals, then 'holds' that value until the next sample. It creates random, stepped voltage changes - perfect for unpredictable modulation.
Do I need multiple LFOs?
It depends! One good LFO can do a lot, but having multiple allows you to layer modulation and create more complex effects. Think of one for vibrato, another for filter movement, and a third for panning.
What's the deal with 'true random' LFOs?
Some LFOs claim 'true random' output, often using external noise sources. This can sound more unpredictable, but it also introduces potential for instability if the noise source isn't clean. It's a subtle difference, but can be noticeable in sensitive patches.
