FillMaster: A Drum Idea Generator / Improvisation Trainer for React

Introduction

This project has been created to inspire ideas for drummers by enforcing rules to use whilst practicing the improvisation of drum beats, particularly fills. It can help beginner improvisers practice playing fills on time and can help any level of player get out of their comfort zone by playing things outside their usual style.

The project is Open Source under GNU GENERAL PUBLIC LICENSE Version 3.

Getting started

Clone the repo and run npm i

Available Scripts

In the project directory, you can run:

`npm start`

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser. Open http://yourip:3000 on your mobile to view on mobile.

The page will reload if you make edits.

`npm test`

Runs the tests. Code must be compiled first using npm run compile.

`npm run compile`

If you need to compile the code to JavaScript. The files will be in the dist folder.

`npm run build`

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

`npm run serve`

Builds the app and runs the server so that you can then go to: http://yourip:3000 on your mobile to view the built app (i.e. not the slower, dev environment app).

About the project:

Small, single-function components (e.g. a custom button) live in the 'elements' folder. All other components including those you may class as a container live in the 'components' folder.

This project uses the react-pro-metronome (RPM) library. It has been imported into the source as the npm version is no longer maintained and has missing audio files. The audio files would have been replaced regardless, as a special tone is used for the fill start. RPM works perfectly as it uses howler.js (which implements the Web Audio API) for a stable tempo. RPM is also easy to interact with, using strings to abstract interaction with the metronome pulses. Metronome.tsx handles interaction with RPM.

RPM is written in javascript and at some point in the future we may update this to typescript and strip out any unused code, but its not a priority as it works perfectly right now. It should remain isolated at least until we have plenty of UI tests in place. This will allow us to focus on implementing new features to FillMaster. The test file in the RPM directory 'tests/index.js' should be named 'tests/index.test.js'; this was changed as there was conflicts with Jest when ts-jest was added so it was renamed so that the test skips. Before any changes to RPM happen, this test must be reinstated and compatibility issues fixed.

Music Counting Basics (and the Metronome Interface)

This will hopefully help non-musicians working on the project or musicians who don't know much theory. It's also a guide for how we communicate with the metronome part of the app.

Musicians often count music to help them keep in time. 4/4 is the most common time signature used in music. See glossary (below) for an explanation of time signatures.

If you decide to play quarter notes (beats) in 4/4. You may count 1, 2, 3, 4, 1, 2, 3, 4.

If you decide to play eighth notes (two notes per beat) in 4/4. You may count 1 and 2 and 3 and 4 and. This can be called the first subdivision.

If you decide to play sixteenth notes (four notes per beat) in 4/4. You may count 1 e & a 2 e & a 3 e & a 4 e & a. This can be called the second subdivision.

If all of these are played at 100 bpm (beats per minute). The numbers would fall in the same place and the subdivisions would fall in between.

If we were to play in 4/8. It would sound identical to 4/4 (its just a naming convention). The first subdivision will now be called 16th notes (as you now are using 8ths as your beat) and the second subdivision will be called 32nd notes.

When making music you can go between beats and subdivisions as much as you want, otherwise the song would be pretty boring. But for the purpose of a metronome we tend to stick to one division at a time.

Exercise:

This is of course completely optional, but if you really want to understand why we count in music. Do the following.

Count out loud 1, 2, 3, 4 (and repeat)
Maintain the same speed but add and in between each number. 1 and 2 and 3 and 4 and.
Now add e (pronounced ee) and a (pronounced ah) on either side of the and. 1 e & a 2 e & a 3 e & a 4 e & a
Now clap your hands on only the beats (the numbers) whilst continuing to count the subdivisions.
Now ALSO clap on the and of 3.
Now ALSO clap on the e and and and a of 4.

You should now be counting like this (with the claps highlighted) 1 e & a 2 e & a 3 e & a 4 e & a.

This is why musicians count. To learn rhythms and to communicate rhythms. Where is that note you are playing? - It's on the 'a' of 3.

How does this translate to the metronome in the app?

The metronome in the app takes a string of numbers.

0 = No sound
1 = Accented click sound to emphasise beginning of the bar.
2 = Regular click sound.
3 = Helper sound. This is what makes Fill Master unique. We can place a helper sound on any sub beat to help the user pick out a certain part of the bar.

In 4/4 timing:

Count:	1	e	&	a	2	e	&	a	3	e	&	a	4	e	&	a
Quarter Notes: the beat	1	0	0	0	2	0	0	0	2	0	0	0	2	0	0	0
Eighth Notes: first subdivision	1	0	2	0	2	0	2	0	2	0	2	0	2	0	2	0
16th Notes: second subdivision	1	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2

Eighth Notes: Helper sound on `Beat 4`	1	0	2	0	2	0	2	0	2	0	2	0	`3`	0	2	0

Note: The above diagram is based on the metronome subdivision setting of 4. i.e. There can be up to 4 notes per beat. We actually default to 8 which allows for a third subdivision. The result is essentially the same but with extra 0s between each beat. If you look at the 'pattern' folder in 'tests' this may help you break down what's happening inside our interface with the metronome.

In 5/4 timing. The above diagram would look the same but the count would go up to 5.

In 4/8 timing. The above diagram would look the same but the beat would be called Eighth Notes, the first subdivision 16ths and the second subdivision would be 32nd notes.

GLOSSARY

Time signature:

Examples: 4/4 , 7/8 , 9/16

The first number is the number of beats per bar (a section of music).
The second number is the beat value.

4/4 = 4 beats per bar. Each beat is worth a quarter note.

7/8 = 7 beats per bar. Each beat is worth an 8th note.

9/16 = 9 beats per bar. Each beat is worth a 16th note.

Note: 4/4, 4/8 and 4/16 all sound identical. Whoever transcribes the music may favour one over the other for legibility.

bpm

Beats Per Minute.

Whether you are in 4/4 or 5/8 at 100bpm, you are playing 100 beats per minute. If you are simply playing a click track, they would sound identical. Musically though they would differ as you would (for example) put an accent on (i.e. hit a bit harder) the first beat of each bar, so every 4 notes or every 5 notes respectively would have an emphasis. You would also perhaps have a guitar riff that loops every 4 notes or every 5 notes. These will sound pretty different.

Of course 50bpm would be half the speed and 200bpm twice the speed. But it is also possible to stay at 100bpm but just play twice as many notes in the same space and it will sound twice as fast.

For example. If you count the beats in 4/4 as 1, 2, 3, 4. If you then put an AND between them and count the numbers at the same bpm. 1 AND 2 AND 3 AND 4 AND, your music will now sound twice as fast but you have not changed the BPM because the beats are only where you count the numbers. This is called subdivision.

Subdivision

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

Performance: It delivers optimal performance.
Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
UI design: React Native enables you to design simple and responsive UI for your mobile app.
3rd party plugins: This framework supports 3rd party plugins.
Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
Near-native user experience: React Native provides several native components, and these are platform agnostic.
The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
React.js and React Native have similar syntax and workflows, but their implementation is quite different.
React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

United States- $120,000
Canada - $110,000
United Kingdom - $71,820
The Netherlands $49,095
Spain - $35,423.00
France - $44,284
Ukraine - $28,990
India - $9,843
Sweden - $55,173
Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

Conduct thorough candidate research, including portfolios and areas of expertise.
Before you sit down with your interviewing panel, do some homework.
Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
