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

|
|
This example applies a series of mappings to a
|
|
signal value and applies the results of those mappings
|
|
to the frequency attribute of 2

|
|
and a <a href="http://tonejs.org/docs/#LFO">Tone.LFO</a>.
