How to choose the best oscillator modules
Stability & Drift
A wandering oscillator is useless. We're looking for rock-solid tuning, especially when pushing into FM territory. Even a few cents of drift can ruin a perfectly good patch, especially in lower registers.
Waveform Character
It's not just about sine, saw, and square. The subtle harmonic content of each waveform - that fat midrange honk on a saw, the clarity of a triangle - is what separates a sterile oscillator from a truly inspiring one.
FM Response
How does the oscillator react when modulated with FM? Does it become brittle and harsh, or does it retain a musicality even at extreme ratios? This is critical for creating complex textures.
Modulation Capabilities
Beyond simple frequency modulation, consider features like pulse width modulation (PWM), wave shaping, and sync. These add a layer of complexity and control crucial for professional sound design.
Phase Control/Randomization
Precise phase control allows for predictable and repeatable results. Random phase capabilities inject unpredictability and organic movement, perfect for evolving soundscapes and textures.
Buying guide
Alright, let's talk oscillators. If you're building a serious modular rig - the kind that's seeing studio time and holding its own in a band rehearsal - stock VCOs just won't cut it. You're not chasing presets; you're sculpting sound. The heart of any synth is the oscillator, and the choices you make here directly impact everything from subtle FM textures to screaming leads that cut through the mix. This isn't about the cheapest option; it's about finding the right tool for the job.
Don't chase the 'most features' - focus on the core sound and stability. Cheaper oscillators often compromise on component quality, leading to tuning instability and a thin, anemic sound. Paying a little more for a well-designed oscillator with accurate wave shaping and solid tuning will pay dividends in the long run.
Consider your patching style; if you're heavily into FM, a wider frequency range and robust FM response are essential.

Questions
What's the difference between a VCO and a DCO?
VCOs (Voltage Controlled Oscillators) use analog circuits, which can introduce a bit of warmth and character but also drift. DCOs (Direct Digital Control Oscillators) are digitally controlled, offering rock-solid tuning and often more waveforms, but can sometimes sound sterile. It's a trade-off between character and precision.
How important is pulse width modulation (PWM)?
PWM is a game-changer for adding movement and complexity to square waves. It's a simple feature, but it can transform a basic oscillator into a versatile sound source.
I'm new to modular. Should I start with a cheap oscillator?
Starting with a budget option isn't terrible for learning, but be prepared to upgrade quickly. A frustrating oscillator will stifle your creativity. Spend a bit more upfront for something reliable.
What's 'sync' and why would I need it?
Sync forces the oscillator to reset to a multiple of the modulating signal's frequency, creating complex, clangorous sounds - think bell-like tones or harsh, industrial textures. It's a powerful tool for creating rhythmic complexity.
My oscillator is drifting out of tune. What can I do?
Temperature fluctuations are the biggest culprit. Ensure your modular case is well-ventilated. Some oscillators have trimpots for fine-tuning; consult the manual. If it's constantly drifting, it's likely a component issue and may need repair.
