How to choose the best oscillator modules
Waveform Variety
Beyond the standard sine, triangle, and square, consider the unique waveforms offered. A good oscillator will give you something beyond the basics - pulse waves with adjustable width for that classic Moog vibe, complex waveforms for evolving textures, or even noise sources for percussion and effects. It's about having sonic options.
Frequency Stability
This is critical. A wandering oscillator will throw off your tuning and make everything sound sloppy. Cheap oscillators often use less precise voltage-controlled oscillators (VCOs) that drift, especially when the temperature changes in your studio. Check reviews and look for oscillators that boast excellent frequency stability.
FM Capabilities
Frequency Modulation (FM) is where things get really interesting. Some oscillators allow you to modulate their frequency with another oscillator, creating complex, metallic, and often harsh sounds. The depth and range of FM control dramatically impacts the sonic possibilities - a little FM goes a long way, but too little is a missed opportunity.
Pulse Width Modulation (PWM)
PWM is a staple for creating thicker, more complex tones. A good oscillator will allow for smooth, controllable PWM, either through a dedicated CV input or a built-in LFO. Watch out for PWM that's stepped or jerky - it'll sound artificial and less musical.
Calibration & Tuning Range
Being able to calibrate your oscillator is vital, especially with VCOs. A wider tuning range gives you more flexibility for experimentation and creating those gnarly detuned sounds, but also requires more careful calibration. Some oscillators are tuned per octave; others let you tweak the entire range.
Buying guide
Alright, so you're diving into modular synths? Awesome. The heart of any modular patch is the oscillator - it's where your sound starts. Picking the right oscillator isn't just about waveforms; it's about the character, the grit, the sustain - the vibe you're trying to create. Let's break down what to look for so you don't end up with a pile of blinking lights and no usable sound.
Don't chase the 'cheapest' oscillator - you'll end up frustrated. The low-end modules often cut corners on component quality, leading to instability and a muddy sound. Look for oscillators from reputable manufacturers with a track record of good build quality and stable tuning.
Spend a little more for a module that'll inspire you and actually hold a note reliably when you need it to - especially if you're gigging.

Questions
What's the difference between a VCO and a DCO?
VCOs (Voltage Controlled Oscillators) are analog oscillators that rely on analog components, leading to potential instability and drift, but also a unique, 'organic' feel. DCOs (Digitally Controlled Oscillators) are digitally controlled, offering much greater tuning stability and often a wider range of waveforms, but can sometimes feel sterile.
Do I need FM?
Not necessarily, but it opens up a huge world of sound design possibilities. If you're primarily after classic subtractive synth sounds, it's less essential. If you want to create clangorous textures and metallic drones, definitely explore FM.
How important is calibration?
Calibration is crucial, especially for VCOs. Even a small amount of drift can make your patches sound out of tune. Get into the habit of calibrating your oscillators regularly, especially after moving them or experiencing temperature changes.
Can I use multiple oscillators together?
Absolutely! That's the whole point of modular synthesis. Combining oscillators - layering, FMing, phase-shifting - is where you can really create unique and complex sounds. Just be mindful of headroom in your mixer.
What's 'wavetable' and does it matter?
Wavetable oscillators cycle through a series of waveforms, creating evolving and complex sounds. They're a digital approach, offering a lot of flexibility, but can sometimes lack the character of a good analog VCO. It's a matter of preference.
