Tone.js/CHANGELOG.md

### 14.2.0

* **Converted to typescript!!! (WIP)**
* Input/Outputs are no longer arrays. 
	* simplifies connect/disconnect logic greatly. Simplifies API to just have clearly named inputs/outputs instead of overloading input/output connect numbers
* Using "Destination" instead of "Master" for output
	* More consistent with Web Audio API
* FrequencyShifter - thanks @Foaly 

### 13.8.19

* Moving to common.js-style code

**Breaking Changes**

* AudioNode.prototype.connect is no longer overwritten. This means that you can no longer connect native nodes to Tone.js Nodes.
* Tone.connect(srcNode, destNode, [ouputNum], [inputNum]) is the way to connect native Web Audio nodes with Tone.js nodes. 

### 13.4.9

* Updating semantic versioning to be more in line with other [semvers](https://semver.org/). Now version is 13.x.x
* logging full version
* Added Object notation for Tone.TimeBase and classes that extend it. 
	- i.e. Tone.Time({'4n' : 1, '8t' : 2})
	- Replacement for deprecated expression strings. 
* Tone.Meter uses RMS instead of peak (thanks [@Idicious](https://github.com/Idicious))
* Tone.Sampler supports polyphonic syntax (thanks [@zfan40](https://github.com/zfan40))
* Building files with [webpack](https://webpack.js.org/)
* Follower/Gate uses a single "smoothing" value instead of separate attacks and releases
* Changing references to `window` allowing it to not throw error in node context
* Testing examples
* Tone.Channel combines Tone.PanVol with Tone.Solo.
* Removing require.html example. 
* adding `partialCount` and `baseType` to Oscillator classes, helps with getting/setting complex types.


### r12

* Consolidating all shims into [shim folder](https://github.com/Tonejs/Tone.js/tree/dev/Tone/shim)
* Using ConstantSourceNode in Signal when available
* switching to eslint from jshint
* Running [CI tests](https://travis-ci.org/Tonejs/Tone.js/) on Firefox, Chrome (latest and canary) and Safari (latest and version 9).
* [Tone.Reverb](https://tonejs.github.io/docs/Reverb) is a convolution-based stereo reverb. [Example](https://tonejs.github.io/examples/#reverb).
* Optimizing basic Oscillator types and many Signal use-case
* Optimizing basic connection use-case of Tone.Signal where one signal is controlling another signal
* Testing rendered output against an existing audio file for continuity and consistency
* Optimizing triggerAttack/Release by starting/stopping oscillators when not playing
* [TickSource](https://tonejs.github.io/docs/TickSource) (used in Clock and Player) tracks the elapsed ticks
	* Improved precision of tracking ticks in Transport and Clock
* `Player.position` returns the playback position of the AudioBuffer accounting for any playbackRate changes
* Removing `retrigger` option with Tone.Player. Tone.BufferSource should be used if retriggering is desired. 

**BREAKING CHANGES:**

* Tone.TimeBase and all classes that extend it not longer support string expressions.
	RATIONALE :
		* Since all classes implement `valueOf`, expressions can be composed in JS instead of as strings
			* e.g. `Time('4n') * 2 + Time('3t')` instead of `Time('4n * 2 + 3t')`
		* this change greatly simplifies the code and is more performant

* Replaced set/get method with ES5 dot notation. i.e. `player.setVolume(-10)` is now `player.volume.value = -10`.
	To ramp the volume use either `player.volume.linearRampToValueNow(-10, "4n")`, or the new `rampTo` method which automaically selects the ramp (linear|exponential) based on the type of data.
* set/get methods for all components
* syncSignal and unsyncSignal moved from Signal to Transport
* Add/Multiply/Subtract/Min/Max/GreaterThan/LessThan all extend Tone.Signal which allows them to be scheduled and automated just like Tone.Signal.
* Deprecated Tone.Divide and Tone.Inverse. They were more complicated than they were useful.

BREAKING CHANGES:

The API has been changed consistently to use `.attribute` for getting and setting instead of `getAttribute` and `setAttribute` methods. The reasoning for this is twofold: firstly, Tone.Signal attributes were previously limited in their scheduling capabilities when set through a setter function. For exactly, it was not possible to do a setValueAtTime on the `bpm` of the Transport. Secondly, the new EcmaScript 5 getter/setter approach resembles the Web Audio API much more closely, which will make intermixing the two APIs even easier.

If you're using Sublime Text, one way to transition from the old API to the new one is with a regex find/replace:
	find `Tone.Transport.setBpm\((\d+)\)` and replace it with `Tone.Transport.bpm.value = $1`.

Or if setBpm was being invoked with a rampTime:
	find `Tone.Transport.setBpm\((\d+)\, (\d+)\)` and replace it with `Tone.Transport.bpm.rampTo($1, $2)`.
