One of the most powerful features of Tone.js is the ability to
|
|
|
|
|
perform math and logic on audio-rate signal. These signals
|
|
|
|
|
can be ramped and scheduled for use as control signals over Audio
|
|
|
|
|
Parameters and other Tone.Signals making it simple to create elaborate,
|
|
|
|
|
interconnected automations.
