What musicians say

Genuine reviews from the App Store.

★★★★★

Great App for the Marching Arts!!

This app is great for programming tempo changes, accelerandos, ritardandos, and other tempi modifications. I made a sequence for every rehearsal section. Wonderful for consistent practice.

Great product!

I'm a music student and I use this app everyday. I really like the different sounds that are available and the fact they can go loud enough to be heard even in chamber ensemble rehearsals.

★★★★★

Amazing

Using the custom function I was able to put in a score for a ridiculously complex work, add accelerandos and ritards. As a professional musician I highly recommend it.

Frequently asked questions

Can I get Metron 4.0 now?

Metron 4.0 will be available soon on the App Store. Version 3.3.3 is downloadable today as a pre-purchase, and 4.0 will be automatically be unlocked if you purchase Metron now.

What time signatures does Metron support?

Metron supports a huge range of time signatures. Even composite time signatures are possible. (The free version has limitations.)

Can I create my own sequences?

Yes — build sequences with any number of bars, each with its own time signature and tempo if you wish, and customize the rhythm patterns within. (The free version is limited to a single bar and limited time signatures.)

How does Metron handle multiple voices?

Metron can play two voices simultaneously, so you can hear intricate polyrhythms and complex musical compositions. (Two voices is only avaiable in the Pro version.)

What is the pitch pipe used for?

The pitch pipe helps you tune your instrument by selecting any pitch within 9 octaves and adjusting the base frequency.

How accurate is Metron?

Metron lays out its audio samples just-in-time with absolute accuracy — there is no drift inherent to Metron itself (SamplePerfect Pulse™ technology). Export a recording of the 1/4 sequence played at 60 bpm and inspect it in an audio editor: you'll find each pulse starts bang on the second for the whole recording. Any timing deviation you might measure is inherent to the minute differences between the device Metron runs on and the device doing the measuring. Every device generates its audio clock from a quartz crystal oscillator, and no two crystals run at exactly their nominal frequency — manufacturing tolerances of a few dozen parts per million are normal, with a further small shift possible as a device's temperature changes. So two devices' "48kHz" clocks are each running at very slightly different real rates, and it's that gap between them that shows up as drift when you compare a recording against an external reference.
