How to choose the best oscillator modules
Waveform Variety
More isn't always better, but a good mix of classic waveforms (saw, square, triangle, sine) plus something a little different (pulse with adjustable width, FM capability) gives you more sonic options to start with.
Stability
A wandering oscillator is a useless oscillator. We're looking for modules that stay in tune, especially when pushed with modulation - crucial for those evolving textures and sub-octave drones.
Frequency Range
A wider range lets you explore both sub-bass frequencies for that low-end thump and higher registers for glassy, bell-like tones. Limited range means limited possibilities.
Pulse Width Modulation (PWM) Control
PWM is your friend. Even basic PWM adds a ton of character to square waves, going from a fat, warm sound to a more reedy, almost vocal tone. Lack of PWM seriously limits tonal possibilities.
Noise Generation
A decent noise source is surprisingly versatile - percussive hits, wind sounds, textural beds. It's a cheap way to add a ton of character, and a lot of oscillators include a surprisingly useful noise output.
Buying guide
Alright, so you're diving into modular synths but your bank account isn't exactly overflowing? Totally get it. Oscillators are the heart of any synth, so skimping here isn't an option, but you can find some serious bang-for-your-buck. We're rounding up the best oscillator modules you can snag for under $200 - let's get patching.
At this price point, you're making trade-offs. Don't expect pristine build quality or a million features. Most modules will have plastic knobs and simpler displays.
The biggest corner that gets cut is often in the complexity of modulation options - don't expect dedicated PWM LFOs built in. Focus on stability and waveform versatility; those are the foundations for any good patch.

Questions
Can I really get a good oscillator for under $200?
Absolutely. There are some seriously clever designs out there. Just manage your expectations - it won't be a Moog, but it can be a workhorse.
What about clones of classic oscillators?
Clones are tempting, but often cut corners on component quality. They might sound similar initially, but stability and long-term reliability can be an issue. Spend a little more on a well-regarded design, even if it's not a direct clone.
I'm new to modular - which oscillator should I buy first?
Start with something versatile. A basic dual oscillator with a good range of waveforms and PWM is a solid foundation. Something like a Mutable Instruments Plaits clone would be fantastic, if you can find it in your budget.
What does 'stability' really mean?
It means the oscillator stays in tune. When you modulate the pitch, it doesn't drift wildly. A stable oscillator is essential for everything from pads to basslines. Unstable oscillators are frustrating.
Are there any hidden gotchas I should be aware of?
Power draw can be a factor. Cheaper modules sometimes have less efficient power supplies, so check the current draw and make sure your PSU can handle it. Nothing worse than a module dying mid-gig.
