Provide a fallback for sampled sounds: play with oscillator

[bwl21]

Request

could we have a fallback to oscillator sounds (not using samples), because

• we sometimes have problems running the sampled sounds (Player does not work on Safari #71).
• When using on slow network connection, downloading the samples might take long.
• For trivial applications, an oscillator sound might be enough

proposal

control by soundfont type "osc"
provide the timbre as another property in the configuration object

I already removed this feature which does not work fine in FireFox.
If you need it, you may code it yourself replacing toaudio5.js.

Firefox Quantum is a vast improvement. It now plays the oscillator sounds very well. And some of my users complained about the sampled sounds ...

I would not replace toaudio5.js but implement an additional class which I could select in AbcPlay to implement the fallback.

Do you still have the code which you removed before?

[bwl21]

Not sure If I still need this as the player is getting better with 1.16 ...

But If, wouldn't it be sufficient to replace load_res() and note_run() accordingly?

[moinejf]

I don't see what you mean.
toaudio5 is a way the play the notes using the web audio API. You may replace it with anything else, as using the html5 MIDI interface and connect a MIDI synthesizer (I have it in vivaldi), or convert the notes to csound commands and pipe them via a HTTP server. There are a lot of ways to produce sound.

My intention was, to use as much as possible from toaudio5 (in particular the timing) but use an osscilaator instead of a soundfont. But as I said, the player is getting better with 1.16, so i close this ticket for the time being.
