What's New in Metric Modulator

1.0.3

November 8, 2026

New in 1.0.3: • Overdub: swipe Play sideways and play a beat in by tapping, on a drum near the mic, or over MIDI. It's quantized and layered onto your beat, with an undo per bar. • Brushes (Pro): Jan's brush kit, with sweeps you hold on the snare. • Ruffs: a new two-grace stroke, above flam. • Library: Paste link, for beat links that open in your mail app instead of here, and a search box once you have lots of beats. • Wait mode forgives a late kick. • Lower audio latency on Android.

Breakthrough for Drum Practice

This is a breakthrough for any drum teacher and student. The teacher can create lesson plans and input them into this app. The lesson plans then are put in the "Library" icon, ready for practice. It has a built-in metronome that can be adjusted to desired tempos, and the lessons are available in two different styled formats that are well designed, easy, easy to use. There is also a PDF option. Brilliant new App! Enjoy!

This makes practicing so much easier.

As a beginner, I often find myself forgetting how to count an exercise. Having the ability to play with the sound of the drum and score my practice has been just what I needed to and make me a better drummer than I thought in a short amount of time.
