AudioKit

Also in this release are some small bug fixes.

We addressed an issue with Xcode 11 and AudioKit.start(withPeriodicFunctions:) that was releasing memory quickly.

• AKSequencer is now Audiokit's open source sequencer
• AKAppleSequencer is introduced (its what used to be AKSequencer)
• MIDI Listener protocol now has sample offset times, make sure to update your listeners

Numerous bugs that were raised as issues were fixed.

Thanks to heroic efforts of Stephane Peter and Jeff Cooper, we have cocoapods working again.

Also includes ability to be sandboxed in macOS.

• AKMIDIFile updates by Jeff
• Microphone initialization updates by Maximilian
• Input Device Selection improvement and more by Dean

Lots of bug fixes and issues closed.

Public-izing and exposure of several properties to Objective-C

Bugfix: MIDI input not working with AKAudioUnitInstrument
https://github.com/AudioKit/AudioKit/pull/1681

And other smaller things

Lots of changes, long list of unrelated changes, some of which are API Breaking:

• AKMIDIStatus is now AKMIDIStatusType and AKMIDIStatus has a type and other MIDI fixes all by Jeff Cooper
• MIDI Clock implementation by Kurt Arnlund
• Microphone fixes for iPhone 6 (by VAndrJ)
• Code refactoring by Adam Nemecek
• Many other bug fixes and enhancements

The main reason for this version is to get out a version with the flurry of fixes by @ryanfrancesconi to AKPlayer issues.

There has also been considerable clean up of AudioKit internals, but that shouldn't affect anything.

• AKSampler key tracking and filter envelope scaling
• Added AudioEngineUnit stuff, groundwork for further development
• Added tests

This is a minor upgrade, but if you are using AKCallbackInstrument, take care for some of the updates.

• Exposed AKNode's auAudioUnit
• Filters in the Core sampler
• Improved Common ADSR Envelope

This release is preferable to 4.5.1 with a more robust microphone fix.

This is a very minor upgrade, but affecting a lot of people's use of AKMicrophone.

AudioKitUI is a static library again and working well. AudioKit playgrounds have also been checked out and are working well with Xcode 10.

This release requires iOS10.0+.

This version was created when Xcode 10 came out and marked our change from AudioKitUI being a static framework to a dynamic framework. Unfortunately this caused macOS apps to break and created a lot of startup warnings even on iOS. AudioKit 4.4 should only be considered if your app does not use AudioKitUI and you can't upgrade to AudioKIt4.5 with Swift 4.2 for some reason.
