How to choose the best synchronizers and clock generators
Clock Stability (Jitter)
This is the big one. Low jitter means tight, consistent timing. High jitter sounds like a subtle warble - you might not hear it consciously, but it kills the vibe and makes things feel sloppy, especially with complex polyrhythms or layered synth pads. Test with a spectrum analyzer if you're obsessive, but your ears are the best judge.
Output Options & Levels
Pro setups rarely involve just one clock signal. You need multiple outputs (BNC, S/PDIF, ADAT, Word Clock) and adjustable output levels to match your gear's impedance. Running a clock signal too hot can introduce noise and distortion - subtle, but it's there.
Tempo Range & Resolution
You're probably not tapping out tempos below 20 BPM or above 240, but the resolution (e.g., 960 PPQ) matters for incredibly tight quantization and nuanced timing adjustments. Think about complex odd-time signatures and precise MIDI sync.
External Tap Tempo & MIDI Clock Control
Essential for live performance. You need to be able to adjust the tempo on the fly - a dedicated tap tempo button is a must, and MIDI clock control gives you even more flexibility. Being able to sync to a live drummer via MIDI is a game-changer.
Feature Set & Complexity
Some units are stripped-down clock generators; others are full-blown sync hubs with routing capabilities and advanced features like phase alignment and signal locking. Consider your workflow - do you need a simple tool or a complex routing matrix?
Buying guide
Alright, let's talk clocking. You're past the days of daisy-chaining a drum machine to your interface and hoping for the best. As pros, we need rock-solid synchronization across multiple devices - digital pianos, synths, effects chains, DAWs - and that means a dedicated synchronizer or clock generator. It's not just about timing; it's about the feel, the groove, and keeping everything locked tight on stage and in the studio, especially when layering complex parts.
Don't cheap out on this. A wobbly clock signal will ruin an otherwise great recording or performance. Entry-level units often cut corners on jitter reduction, resulting in audible timing inconsistencies.
Spending a bit more on a unit with a reputation for rock-solid stability - like a Mutec Systems or a Jenning - is an investment in the overall quality of your work. Consider the future too - a unit with more outputs and flexible routing will age better than a basic model.

Questions
What's the difference between a clock generator and a synchronizer?
A clock generator just outputs a timing signal. A synchronizer does that and can receive external clock signals, allowing it to lock to other devices.
How important is BNC connectivity?
BNC is the gold standard for Word Clock - it's a balanced connection that minimizes noise and interference. S/PDIF and ADAT are fine for simpler setups, but BNC is preferred for critical applications.
Can I use a DAW as my clock source?
Sure, but it's rarely the most stable option. DAWs can be affected by CPU load and plugin processing, introducing jitter. A dedicated clock generator provides a cleaner, more consistent reference.
What is phase alignment and why do I need it?
Phase alignment compensates for slight timing differences between clock signals, preventing build-up of comb filtering and improving the overall clarity and punch of your audio. It's particularly important when syncing multiple digital devices.
I only need to sync a few pieces of gear. Is a simple clock generator enough?
Probably. But consider future-proofing. A slightly more feature-rich unit now might save you headaches later when your setup expands. You'll thank yourself.
