[sug1no]

On load https://g200kg.github.io/webaudio-tinysynth/jstest.html by {osx, iOS} safari the following error occurred:

Can't find variable AudioContext.

the following is a fake workaround (need panner support...) to avoid error:

Thank you for the great product. Are there any plans to support Safari?

[g200kg]

Thank you!!

Until now I did not think about mobile devices. Though it may become intense CPU consumption, I will think about that when I can have the time.

[g200kg]

Now, iOS Safari has supported.
