* Tone.Param wraps the native AudioParam and allows for unit conversion.
* Quantization with Transport.quantize and using "@" in any Time. [Read more](https://github.com/Tonejs/Tone.js/wiki/Time).
* Control-rate generators for value interpolation, patterns, random numbers, and markov chains.
* Scheduable musical events: Tone.Event, Tone.Loop, Tone.Part, Tone.Pattern, Tone.Sequence.
* Player's playbackRate is now a signal and Noise includes a playbackRate signal.
* All filterEnvelopes use new Tone.FrequencyEnvelope with frequency units and `baseFrequency` and `octaves` instead of `min` and `max`.

* Renamed Tone.EQ -> Tone.EQ3.
* Tone.DrumSynth makes kick and tom sounds.
* Tone.MidSideCompressor and Tone.MidSideSplit/Tone.MidSideMerge

* Renamed DryWet to CrossFade
* Functions return `this` to allow for chaining. i.e. `player.toMaster().start(2)`.
* Added `units` to Signal class which allows signals to be set in terms of Tone.Time, Tone.Frequency, Numbers, or Decibels.
* 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)`.
