Hey hexdump! I have known about your project since quite long, and advertised it as appropriate whenever I could, though in a parallel to your effort and unaware of it I ported VCV 1.x to ARM myself quite some time ago, but never was very public about it. I use sse2neon because it is so much simpler and I’d rather add the missing intrinsics there than using the much more complex SIMDe project. I do have the patched sources, but they are still messy, meant for internal use only so far. I will clean them a little and put them on my github soon. You can still find them on a telegram group called “The Patch Bay” - hosted by Vega Deftwing - one of the VCV plugin developers. What you may be interested most likely are the optimization flags I used. I compiled almost everything with LTO, and I am pretty satisfied with the performance so far.
