The ST1K is a synthesizer-focused tuner that merges Korg’s legendary experience in tuner technology with a deep understanding of the characteristics of analog and modular synthesis. Designed with the unique needs of analog and modular synth players in mind, the ST1K is compact, precise, and offers high visibility, ensuring your synth is accurately tuned the way you want every time.

Analog synthesizers can be tricky to tune, with their pitch often fluctuating as the circuit adjusts to temperature changes. You may also want to microtune different oscillators within the one synth. These requirements make reliable tuning essential, whether you're recording in the studio or performing live.

The ST1K delivers this with its capability for ultra-precise tuning to ±0.1 cent, and features a large CMD LCD display that provides a clear, visually appealing readout of your tuning status, aligning with the aesthetics of modular and analog synths. It also includes a built-in high-sensitivity microphone, expanding its use to a broader range of instruments.

At only 83 grams, this incredibly compact and light tuner is perfect for musicians and performers on the move.
