Toggle Metronome Click    K

Turns the metronome on and off. I should try doing this while working on a track sometime, just to hear how far things may slip.

Use the metronome in Logic Pro — Apple Support

Logic Pro includes a metronome, which plays a steady beat (like a “click track”) to help you play and record in time. You can turn the metronome on or off when you’re recording, or any time your project is playing. The metronome always plays at the project tempo. This means that if a tempo map has been created by Smart Tempo, the metronome automatically follows it. It also means that if Smart Tempo is automatically adapting the project tempo to the performance being recorded, the timing of the metronome adapts along with it. For more information about Smart Tempo, see Logic Pro Smart Tempo overview.

“K” is for Klopfgeist | Logic Pro

Klopfgeist is the software instrument that powers Logic’s Metronome function. For many of us, there’s not much more to think about with the Klopfgeist other than enabling the Metronome and hitting “record.” But there’s plenty to dig into with our trusty and unwavering click. Whether it be for utility or creativity.
