Umm... Fast or Slow? (We Guess™)

Keepin' the beat steady is literally the whole point of not soundin' like a garage band havin' a seizure. Too often y'all pick some random tempo that sends your drummer into a spiral of existential dread, searchin' for the groove while everyone else is just… lost. Pro tip? Lock in a tempo & save it with the song so nobody has an on-stage meltdown. OnSong makes this shizzle simple with a built-in metronome that remembers your BPM. But ZOMG — how do you even find the tempo when it just feels right?

Say hello to OnSong®'s tempo detection, which literally listens to your music with the built-in mic & figures out what tempo y'all are actually playin' (shocking, we know). Whether your band is blowin' through the tune or you're just clapin' like an enthusiastic seal, tempo detection learns the beat & automatically updates your song's tempo. Once it figures it out, OnSong® stops listenin' & saves the change. Now your metronome can finally keep everyone from fallin' apart.

Tempo Detection first tries to eavesdrop on any MIDI clock signals floatin' around. If nothin' comes through, it'll switch to listenin' via the built-in microphone or whatever audio input you got to catch beats from your music or general noise pollution.
