13.8.24

  • 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. 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)
  • Tone.Sampler supports polyphonic syntax (thanks @zfan40)
  • Building files with webpack
  • 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
  • Using ConstantSourceNode in Signal when available
  • switching to eslint from jshint
  • Running CI tests on Firefox, Chrome (latest and canary) and Safari (latest and version 9).
  • Tone.Reverb is a convolution-based stereo reverb. Example.
  • 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 (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

r11

r10

  • Transport.on("start" / "stop") callbacks are invoked just before the event.
  • Param can accept an LFO description in the constructor or .value
    • e.g. param.value = {min : 10, max : 20, frequency : 0.4}
  • Time.TimeBase has clone/copy methods.
  • Tone.Buffer.prototype.load returns Promise

  • All filterEnvelopes use new Tone.FrequencyEnvelope with frequency units and baseFrequency and octaves instead of min and max.
  • Phaser uses "octaves" instead of "depth" to be more consistent across the whole Tone.js API.
  • Presets now have their own repo

DEPRECATED:

  • setTimeout, setInterval, setTimeline in favor of new schedule, scheduleOnce, and scheduleRepeat.
  • Tone.Signal no longer takes an AudioParam in the first argument. Use Tone.Param instead.

  • 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).
