## What is Metron (Pro Metronome)?

Destacado pela Apple como "New and Noteworthy" em março de 2010, o Metron é um metrónomo popular e preciso, apreciado por amadores e profissionais.

Criado por um músico com formação clássica, o Metron ajuda na prática de escalas, excertos e composições completas. Com um painel frontal intuitivo, começa a praticar de imediato, como em qualquer metrónomo básico. Um painel traseiro dá acesso, com um toque, a uma vasta variedade de indicações de compasso comuns, e permite criar ou editar sequências, com acesso total às funcionalidades avançadas e exclusivas (Pro).

O Metron oferece indicações de compasso mistas com agrupamento de batidas, escalonamento de tempo e accelerando/ritardando dinâmicos através de um motor de reprodução de alta precisão. Um sequenciador baseado em notação oferece controlo detalhado sobre o tempo, mudanças de compasso, padrões rítmicos com quiálteras, sons de batida individuais, controlo de volume e mais. Pode até tocar duas vozes em simultâneo: três contra dois, cinco contra quatro, ou polirritmias mais complexas.

Um tutorial inicial ajuda a orientar-se rapidamente, com um manual do utilizador completo disponível.

Gratuito para descarregar e utilizar, com um desbloqueio único do Metron Pro para as funcionalidades avançadas; os clientes anteriores à versão 4.0 mantêm acesso total.

Funcionalidades em detalhe:

Metrónomo:
• Modo retrato e paisagem.
• Tempo nominal de 1 a 999 batidas por minuto (efetivamente entre 0,25 e 1998 bpm).
• Opção para alterar o tempo em incrementos tradicionais.
• Accelerando e ritardando ("Variance").
• Escalonamento de tempo (útil em sequências elaboradas).
• Polirritmias (duas vozes em simultâneo).
• Defina um fator entre um quarto (0,25) e o dobro (2,0) do tempo atual (útil ao praticar sequências com tempos definidos).
• Toque no ecrã para definir o tempo com o dedo.
• Precisão: amostras reproduzidas just-in-time com precisão absoluta.
• Mantém a precisão com o ecrã bloqueado.
• Controlo de setlist.
• Opção para o Metron continuar a tocar em segundo plano.
• Grave sessões do Metron em áudio e partilhe as gravações ou as sequências.
• Exporte pistas de tempo MIDI — leve o seu mapa de tempo diretamente para uma DAW.
• Navegue em sequências longas através de marcas de ensaio.

Sequenciador:
• Crie a sua biblioteca com qualquer número de sequências; um conjunto com as indicações mais comuns vem incluído por predefinição.
• Crie sequências com qualquer número de compassos (cada um com a sua indicação simples ou complexa; misture indicações e tempos livremente; acentue qualquer batida).
• Cada sequência pode ter uma contagem decrescente e definir se o metrónomo para no fim ou repete continuamente, com a opção de repetir também a contagem a cada repetição.
• Cada compasso tem uma ou mais indicações de compasso e pode ter tempos e accelerando ou ritardando em qualquer batida.
• Uma indicação de compasso pode ter entre 1 e 64 batidas sobre um denominador pontuado ou não pontuado.
• Uma indicação de compasso pode ser subdividida em grupos de batidas, para acentuar qualquer batida, pois o agrupamento afeta a reprodução. O Metron distingue a primeira batida, batidas acentuadas e não acentuadas, para saber sempre onde está no compasso.
• Introduza notas livremente para criar padrões rítmicos (tercinas, swing ou quase qualquer padrão). Atribua uma cor, som e volume personalizados a qualquer batida ou componente rítmico: tão simples ou elaborado quanto precisar.
• A edição é feita numa única pauta, com espaço para duas vozes, em notação ocidental tradicional. Arraste elementos para a partitura ou trabalhe mais depressa com o modo de inserção baseado em cursor (com suporte opcional de teclado).

Diapasão:
• O Metron inclui um diapasão que ajuda a afinar o seu instrumento. Escolha facilmente qualquer altura dentro de 9 oitavas.

### 5/5 — Issue fixed!

*2026-07-29*

Many thanks to the developer! Very responsive, and fixed the problem in an update.

### 5/5 — Update: Downgrade issue fixed

*2026-07-29*

Previously gave the app three stars because the update/redesign resulted in not being able to restore the previous purchase. They fixed this in the latest update, and all is well now—thanks!!

**Developer response:** Dear AMsonIII,

That is not supposed to happen. Seems like you’ve hit a bug. Please contact us directly at info@sintraworks.com. We will try to resolve this for you a.s.a.p.

Update: We found an issue where some long-time customers were not recognised as existing purchasers. This has been fixed in version 4.0.1, which is out now. Please update to the latest version. (And please update this review if the update fixes the issue for you.)

### 5/5 — Serious tool

*2022-07-21, version 3.3*

The polyrhythm features in this app are amazing. No other metronome comes close

### 1/5 — App was great before iOS 11 and 64-bit apps

*2019-12-13*

This app was great and easy to use for creating sequences before iOS 11. The app temporarily didn’t work when iOS 11 began running 64-bit apps. The developer eventually updated the app, but it doesn’t work the same anymore. I wish there was a website or video with directions for creating sequences with multiple meters. The developer needs to release a page with detailed instructions with the latest updates for creating more complicated sequences. You’re better off looking for another app for creating rhythms and extended metronomes with meter changes for practicing.

**Developer response:** Hi,

Thanks for your review. The website now contains tutorial videos and a downloadable pdf user manual.

### 1/5 — Doesn’t work, no support, con

*2019-07-22, version 3.0.1*

No support (developer website is dead). Makes hideous electronic squeals and awful digital drones. Clicks don’t work. No instructions. Total con. Thanks for nothing. How about my money back, Apple?

### 1/5 — Really poor documentation

*2018-11-19*

There is none that I can find. App lets one put any number of note values in a bar, so what sense is it to have meter? I see no way to make a simple thing like a triplet. Do not purchase this app.

**Developer response:** I know this reply is incredibly late, but if you still wish to have a go at Metron, you can contact us through email and will be more than happy to guide you through and explain its features.

### 1/5 — Waste of money

*2018-01-16*

“Extensive tutorials” don’t seem to exist. App crashes every few times you interact with it. Do not recommend.

### 5/5 — Great App for the Marching Arts!!

*2014-08-01*

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. Little buggy at times but, if your a music professional this is a MUST HAVE!

### 1/5 — Doesn't work

*2013-12-08, version 2.7.1*

On iPhone 4 iOS 6 or iPad 2 iOS 7.  Eg in sequencer a bar of 6/8 leaves grey quavers that stuff the bar too full.

### 4/5 — Great functionality but UI could be better

*2013-07-10, version 2.7.1*

Not the best looking and a little fiddly, but excellent fuctionality for practicing intricate stuff
