I have simply added 'swing' functionality to the sequencer demo provided. Also now works as a universal app instead of just iPad. The rest of the README is the same as provided in the original sequencer demo. Original available at: https://github.com/arielelkin/Sequencer/
Example use of the sequencer plugin for The Amazing Audio Engine.
##Use
Clone this repository, add pod 'TheAmazingAudioEngine' to your pod file or manually add The Amazing Audio Engine.
In this example we will play a sound every quarter note:
//Add an audio file to your Xcode project and get its `NSURL` :
NSURL *woodblockSoundURL = [[NSBundle mainBundle] URLForResource:@"woodblock" withExtension:@"caf"];
//Next, specify when the sound should play in relation to the whole sequence,
//by adding instances of AESequencerBeat to your AESequencerChannelSequence.
//The onset property of an AESequencerBeat should be between 0 and 1.
AESequencerChannelSequence *woodblockSoundSequence = [AESequencerChannelSequence new];
[woodblockSoundSequence addBeat:[AESequencerBeat beatWithOnset:0]];
[woodblockSoundSequence addBeat:[AESequencerBeat beatWithOnset:0.25]];
[woodblockSoundSequence addBeat:[AESequencerBeat beatWithOnset:0.50]];
[woodblockSoundSequence addBeat:[AESequencerBeat beatWithOnset:0.75]];
//Then, create a AESequencerChannel that will play the sequence:
woodBlockSoundChannel = [AESequencerChannel sequencerChannelWithAudioFileAt:woodblockSoundURL
audioController:audioController
withSequence:woodblockSoundSequence
numberOfFullBeatsPerMeasure:4
atBPM:120];
//Add the channel to the `AEAudioController`:
[audioController addChannels:@[woodBlockSoundChannel]];
//Tell it to start playing:
woodBlockSoundChannel.sequenceIsPlaying = true;
Happy sequencing!
