Tone.js/CHANGELOG.md

r4 - Cool is cool

• toFrequency accepts notes by name (i.e. "C4")
• Envelope no longer accepts exponential scaling, only Tone.ScaledEnvelope
• Buffer static progress and load events which tracks the progress of all downloads
• Buffer only accepts a single url
• Sampler accepts multiple samples as an object and can set using setSample
• deprecated MultiSampler - use Sampler with PolySynth instead
• added cdn - please don't use for production code

r3 - Expressive Signal

Core Change:

• Swing parameter on Transport
• Player loop positions stay in tempo-relative terms even with tempo changes
• Envelope ASDR stay in tempo-relative terms even with tempo changes
• Modified build script to accommodate using requirejs with build and minified version

Signal Processing:

• Tone.Expr: signal processing expression parser for Tone.Signal math
• All signal binary operators accept two signals as inputs
• Deprecated Tone.Threshold - new class Tone.GreaterThanZero
• NOT, OR, AND, and IfThenElse signal logic operators
• Additional signal classes: Inverse, Divide, Pow, AudioToGain, Subtract
• Scale no longer accepts input min/max. Assumes [0,1] range.
• Normalize class if scaling needs to happen from other input ranges
• WaveShaper function wraps the WaveShaperNode

Effects:

• Distortion and Chebyshev distortion effects
• Compressor and MultibandCompressor
• MidSide effect type and StereoWidener
• Convolver effect and example

Synths:

• Setters on PluckSynth and PulseOscillator
• new PWMOscillator
• OmniOscillator which combines PWMOscillator, Oscillator, and PulseOscillator into one
• NoiseSynth

r2 - Getting Physical

• PluckSynth - Karplus-Strong Plucked String modeling synth
• Freeverb
• John Chowning Reverb (JCReverb)
• LowpassCombFilter and FeedbackCombFilter
• Sampler with pitch control
• Clock tick callback is out of the audio thread using setTimeout
• Optimized Tone.Modulo
• Tests run using OfflineRenderingContext
• Fixed Transport bug where timeouts/intervals and timelines were on a different tick counter
• AmplitudeEnvelope + triggerAttackDecay on Envelope
• Instruments inherit from Tone.Instrument base-class
• midi<-->note conversions

r1 - First!
