Metric Modulator

Metric Modulator is a polyrhythm metronome, beat designer, and drum practice tool. • Design a groove on up to 8 tracks, no limit on duration. • Set a time signature, divide beats up to 12x, repeat measures, set loop points, and modulate the tempo from one measure to the next. • Mark notes as LH or RH, add accents, flams, rolls, open hi-hats and cross sticks. • View beats in a grid layout or as traditional notation, with a bouncing-dot cursor to follow along. Tap any measure to play from there. • Practice playing with touch, mic or MIDI input. The mic learns the sound of your own drums. • Shows where you are rushing or dragging, tracks your progress and best score. • Ramp tempo gradually to master a groove, mute bars and random hits to add challenge, or let the beat wait for you at each note. • Play a beat a set number of times, then stop. • Share your beats as links and QR code images on social media, or turn a photo of a drum chart into a beat with your favorite AI assistant. • Customize samples and instruments, and balance tracks in the mixer. • Smooth 120 Hz display (on supported devices), sample-accurate audio engine, advanced on-device hit analysis, latency compensation. Developed by a jazz drummer and game programmer duo, this app has everything you need to design, practice, and master complex rhythms. Free, with no ads. A one-time Pro upgrade unlocks all eight tracks, unlimited saved beats, tempo ramps, dropout, wait mode, practice history, MIDI input, notation printouts, and custom samples.
