A Rhythm Box System for your iOS app 🎵. The easiest way to create Music Rhythm Patterns in Swift.

What can I do with RhythmBox?

• Generate a BPM or RPM Tempo
• Select the Time Signature
• Create a Rhythm pattern

Demo Project

To run the example project, clone the repo, and run pod install from the Example directory first.

Getting Started

Requirements

• iOS 8.0+ / tvOS 9.0+
• Xcode 8.0+
• Swift 3.0+

Installation with CocoaPods

CocoaPods is a 3rd-party dependency manager for Swift and Objective-C projects. For more information, refer to the CocoaPods Getting Started Guide. Otherwise, you can install CocoaPods with the following command:

$ gem install cocoapods

Podfile

source 'https://github.com/CocoaPods/Specs.git'
pod 'RhythmBox'

Then, run the following command:

$ pod install

Installation Manually

To integrate RhythmBox into your Xcode project manually, just include the filest from /Pod/Classes/ folder in your App’s Xcode project.

Quick Guide

Usage

To Generate a constant BPM signal is as simple as this.

1. Import class

import RhythmBox

2. Create a RhythmBox class

let rhythmBox = RhythmBox(bpm: 120, timeSignature: (4,4))

3. Start the Rhythm

rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    print("CurrentSubBeat", CurrentSubBeat)
    print("CurrentNote", CurrentNote)

    return .resume
}

4. Stop the Rhythm

rhythmBox.stop()

Examples

Example 1

Create a 120 BPM signal with a block.

let rhythmBox = RhythmBox(bpm: 120)
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}

Example 2

Create a 150 BPM signal with a time signature of 6/8 with default subdivision of

let rhythmBox = RhythmBox(bpm: 150, timeSignature: (6,8))
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}

Example 3

Create a 90 BPM signal with a time signature of 3/4 and subdivision of

let rhythmBox = RhythmBox(bpm: 90, timeSignature: (3,4), subdivision: "11")
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}

Example 4

Create a 90 BPM signal with a time signature of 3/4 and subdivision of

let rhythmBox = RhythmBox(bpm: 90, timeSignature: (3,4), subdivision: "111")
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}

Example 5

Create a 90 BPM signal with a time signature of 3/4 and subdivision of

let rhythmBox = RhythmBox(bpm: 90, timeSignature: (3,4), subdivision: "011")
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}

Example 6

Create a 90 BPM signal with a time signature of 3/4 and subdivision of

let rhythmBox = RhythmBox(bpm: 90, timeSignature: (3,4), subdivision: "10111")
rhythmBox.perform {CurrentBeat, CurrentSubBeat, CurrentNote in

    print("CurrentBeat", CurrentBeat)
    return .resume
}
