We didn't really get into how "possible" it is to produce EDM at high sample rates, given today's hardware. I've read some posts over at gearslutz.com (posted a link in one of my earlier posts) that show some producers are doing just that. Not sure if it's 192, but at least 96 kHz.
The link discusses a different topic for the most part. Just because some people work at 96k (setting their DAW's sample rate to 96k) it doesn't automatically mean that there will be any frequencies over 22kHz. Typically there won't be any, unless they directly forced their synths to do so, in which case, they would most likely run into the same kind of problems as I did. Maybe they could record some acoustic instruments at 96kHz and then use that in their music but this is again an entirely different case.
"soft synths and dsp/fx plugins often sound much better at higher sample rates - even if the benefit is just less audible aliasing
over sampling plugins help too - try guitar rig with/without the 'high' quality mode on... the difference is huge and pronounced
a final format of 16/44.1 doesn't negate the benefits"
This could be a noteworthy post, as this explains how I made my synth to make ultrasonics. First, I chose a signal which had enough frequencies above 22kHz. Normally, these frequencies would alias back below 22kHz which could alter the sound in a very noticeable way. The higher the original frequency were, the lower the aliased frequency would be. So, after applying enough oversampling, none of the strong/loud harmonics were aliased. This alone wouldn't be enough to produce ultrasonic content, because if the DAW's sampling rate was at 44.1kHz, all the high frequencies would be filtered out. So after the oversampling I also had to change that to 192kHz so the frequencies wouldn't get filtered up to ~96kHz.
As you can see, the high frequencies is just a byproduct of oversampling (which is typically being used for anti aliasing not for making high frequencies). Even the post's maker says "the final format of 16/44.1 doesn't negate the benefits."
