How to choose the best oscillator modules
Stability
A wandering oscillator is a frustrating oscillator. Beginners need something that locks in reliably, especially if you're planning on using it for basslines or drones - those frequencies need to be solid.
Waveform Variety
A simple sine, sawtooth, and triangle wave will get you a long way. Having a pulse wave with adjustable width adds a ton of versatility for everything from fat basses to glassy leads. Don't get bogged down in complex waveforms initially.
Playability/Calibration
Can you easily tune it? Does it drift out of tune quickly? A beginner-friendly oscillator will have a straightforward tuning knob and minimal drift, so you can focus on making sounds, not fighting the module.
Noise/Cleanliness
Cheap oscillators can have a lot of unwanted noise or aliasing. Listen for hiss, clicks, or a harsh, brittle sound, especially in the higher registers. A clean oscillator gives you a solid foundation to build on.
Modulation Input
While you don't need a PhD in modulation, having a simple FM (Frequency Modulation) input is a huge bonus. It opens up a world of evolving, complex tones without needing a ton of extra modules.
Buying guide
So, you're diving into the modular world? Awesome. One of the first, and most crucial, modules you'll need is an oscillator. It's the heart of your sound, generating that fundamental tone that everything else builds on. Picking your first oscillator can feel overwhelming, but let's cut through the noise and find something that'll get you making music, not tangled in menus.
Don't chase the fancy features right away. A basic, stable oscillator is far more valuable than a feature-packed one that's noisy or drifts out of tune. You'll often find that cheaper oscillators cut corners on component quality, leading to more noise and instability.
Paying a little more for a reputable brand and a well-designed circuit will save you headaches down the line. It's better to have a clean sine wave than a complex waveform that sounds like digital garbage.

Questions
What's the difference between sawtooth and square waves?
Sawtooth waves have a ramp-like shape, giving you a bright, almost reedy tone. Square waves have a sharp, abrupt transition, creating a more buzzy, aggressive sound. Both are essential building blocks.
My oscillator sounds 'fuzzy' - what's going on?
That's likely aliasing, a byproduct of how oscillators generate waveforms. It's more common in cheaper modules. Try filtering out the higher frequencies with a low-pass filter or using a waveshaper to tame it.
What does 'FM' mean?
Frequency Modulation. It's when one oscillator (the modulator) changes the frequency of another (the carrier). It's a powerful way to create complex and evolving sounds, but can also get wild quickly.
I'm on a tight budget - what's the absolute cheapest option?
Mutable Instruments Plaits is a great starting point, offering multiple oscillators in one module, though the complexity can be a bit much initially. Otherwise, look for used Erica Synths Black Wavetable or Intellijel Dixie II - solid performers at reasonable prices.
Do I need multiple oscillators?
Not initially. One solid oscillator will get you far. As you progress, adding more oscillators for layering, detuning, and FM will expand your sonic palette, but start with a good foundation.
