I'm very curious to see this transition to ARM play out. There is a lot of software that will now be compiled for ARM that can potentially be used in open-source projects on much more cost-effective boards. Music (VST) plugins come to mind.

VSTs are already really easy to compile for ARM and iPads have been ubiquitously supported for a long time now.

VST? Is that like an AU?

Kidding, but since you mentioned iPad...

Well the caveat is that the code for a VST could be easily compiled for an ARM target and the result would be an AU.

It would just be a VST built for ARM, no? They’re different plugin interfaces.

Depends really. Something like iPlug2 (https://github.com/iPlug2/iPlug2) would allow you to write code once and compile to all these targets.
