Tonejs/Tone.js r6

on GitHub

Big changes are the new event classes: Tone.Event, Tone.Loop, Tone.Part, Tone.Sequence, and Tone.Pattern. These simplify interacting with the Transport.schedule (formerly Transport.setTimeline). They allow you to more easily schedule loopable, schedulable, and modifiable events along the Transport's timeline.

All Changes:

• Added PitchShift and Vibrato Effect.
• Added Timeline/TimelineState/TimelineSignal which keeps track of all scheduled state changes.
• Clock uses requestAnimationFrame instead of ScriptProcessorNode
• Removed onended event from Tone.Source
• Refactored tests into individual files.
• Renamed some Signal methods: exponentialRampToValueNow->exponentialRampToValue, setCurrentValueNow->setRampPoint
• LFO no longer starts at bottom of cycle. Starts at whatever phase it's set at.
• Transport is an event emitter. triggers events on "start", "stop", "pause", and "loop".
• Oscillator accepts a "partials" array.
• Microphone inherits from ExternalInput which is generalized for different inputs.
• New scheduling methods on Transport - schedule, scheduleOnce, and scheduleRepeat.
• Tone.Gain and Tone.Delay classes wrap the native Web Audio nodes.
• Moved MidiToScore and TypeScript definitions to separate repos.
• Tone.Param wraps the native AudioParam and allows for unit conversion.
• Quantization with Transport.quantize and using "@" in any Time. Read more.
• 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.
• 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.
• Tone.Buffer.onload/onprogress/onerror is deprecated. Use Tone.Buffer.on("load", callback) instead.
