Plugins that support multicore on Apple Silicon?

[aMUSEd]

Are any plugins actually designed to utilise multiple cores in Apple ARM architectures or was multicore only really designed with Intel in mind?

So far out of all plugins I have tested the only plugins that I can find where performance does actually improve with the multicore option enabled are u-he CLAP plugins inside Bitwig. Using multicore with these in the VST3 or in hosts that don't support CLAP results in much worse performance. But this isn't so much because they were designed for ARM but because CLAP plugins are better designed to make use of multiple threads generally (in supporting hosts obviously).

The only non CLAP plugin I've tested that comes anywhere close is Pianoteq 7 where the multicore setting doesn't actually degrade performance (although to be fair it doesn't seem to improve it noticeably either)

Of course my M1 Max is plenty fast anyway so I'm not too bothered by CPU being over used but any performance benefits are still welcome.
