If all you want is your synth's view link, just copy what's in your web browser's address bar when you're viewing your synth and don't bother using the 'Share' button.
If you want to link to the image that you're currently paused on, then use the 'Share' button to get a 'Share link'.
To change to the embed link, just change the word 'view' in a synth's view URL to 'embed'.
Whenever you copy the embed code for a synth, you'll notice that there are some switches:
'delayload' can be set to either 'true' or 'false' and controls whether the synth will load with the rest of the page or wait until it is clicked.
The default value for embed links is 'true' + 'false' for view links if not specified.
'autoplay' can also be set to either 'true' or 'false' and controls whether the synth will immediately start playing as soon as the synth loads (whether it loads with the page or needs to be clicked before loading). The default value is 'true' if not specified.
